dedicated-server

[final current]

Can you give us some more detail. What do you mean when you say upload? Is the server hosted by a 3rd party? Is it on the same PC as your gaming client? Are you running Linux, macOS, or Windows for the server, and how about for the gaming client that holds the world you want?

Jaga had a message here earlier about the -world <world name> argument, which is definitely an important part as well. You can paste us your server's launch arguments if you want us to double-check them.

[rugged sorrel]

How can I add grief prevention to a server without any player downloaded mods?

[knotty oracle]

How would that even work?

[rugged sorrel]

Host/client side mods?

I assume they exist

[plain trellis]

The only way I'm aware of are a server forcing set of mods that clients need to have, to be able to log in. And one of those mod could be a "anti-grief" prevention. Out of the 5.000+ mods for Valheim, only a handful of mods are purely server side, and therefor able to be used by none-modded clients (like Xbox). But there is no servers out there that can prevent grief, when client can load what ever mods they like.

[crude cove]

Okay here it is, I removed the IP in all the places I found

[final current]

Thanks. The relevant line is deep in there but it looks like you're missing the MSVC C++ runtime libraries, required for Crossplay in the Windows versions of Valheim. Just means you haven't installed any other software that's needed them yet.

You can grab a standalone installer at https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

Hey all! I'm a AWS Cloud Engineer and I've been running a Valheim server on an EC2 instance for my family. I'm running the mbround18 container on an Amazon Linux 2023, which has worked wonders so far! I have monitoring making sure the Valheim container has more than enough RAM, CPU, and storage (running on a 16GB t3.xlarge instance at the moment).

The only issue I'm having is that we have a large base that seems to cause a lot of lag on the game clients. I.e. actions taking some time to take affect if they ever do. Sometimes I'll put ore in a smelter and it will leave my inventory but never show up in the smelter.

I'm a Python dev working with data, so this is not my expertise at all. Is this the right place to ask? And is there a way I can improve performance or is this a limitation of the Valheim client?

[knotty oracle]

Large bases with large numbers of instances will cause lag. I don't think there's much you can do about that.

[spiral bluff]

Understood 👍 It seems like the game loads instances at a certain rate and doesn't exceed it. Sounds like we should move certain components out of our main base

[final current]

Derek probably has the right of it. Also, if you're using Crossplay, that will amplify the network side of lag significantly.

I'm guessing you've already checked your credits for bursting in CloudWatch, but if you haven't it's worth a gander just in case. You might see correlating plateaus in the CPU graph when those are exhausted

[spiral bluff]

Great to know about Crossplay!

And yes, I'm watching the bursting creds, though I have a pretty beefy server running and I export resource stats to Cloudwatch and to a dashboard

[final current]

I don't remember which kernel Amazon Linux 2023 has, but if it's pretty new, you can sometimes get better latency using ipvlan networking instead of docker or podman's default of a bridge. We're talking tiny improvement though, nothing that will cure base instance count woes

[final current]

https://docs.docker.com/engine/network/drivers/ipvlan/ for a good overview and example @spiral bluff
it's pretty similar on the podman side if you're using that. You would drop host port-forwarding if you go with an ipvlan interface as you'll get the singular IP address isolation.

If you're using Kubernetes instead, definitely consider the aws-vpc-cni if you aren't already.

[plain trellis]

The client that enters a cell ingame first, is responsible for calculations for every player in that cell. So a Valheim server can almost run on a RasPi, because of this.

[spiral bluff]

Very interesting, thank you for that!

[spiral bluff]

Oh that's good to know. One of our group has an older PC. The rest of us have pretty solid machines

[quaint quarry]

I cant join my dedi because of a version missmatch even though both the client and the server are on 0.220.5

Something isnt right there xd

[quaint quarry]

after reinstalling both the server and the client it works again

[calm phoenix]

I started on someones dedicated server and they cant activate the fire hazard feature, any help?

[quaint quarry]

Nevermind, it came back right after playing on it once

no restarts in between though

[plain trellis]

You need to look at the logs for the server and the client, to see what could be the reason. Using any mods?

[quaint quarry]

for some reason it worked again after verifying game files and removing a key

[final current]

How did they try to activate it? Welcome to send them here. There are a couple of ways to do it. One of the easier ones is to add the -setkey Fire argument to the server's launch.

Another approach is if they are good/careful at world management, they can open the world in a local game client, change the key using the World Modifier dialog, and copy the world back to the dedicated server.

If they don't mind a character getting marked as a cheater, they can also log in as an adminlist-ed admin player and use setkey Fire while in the devcommands context.

[jade bone]

is there a way to setup a dedicated server in this game without doxxing your ip address?

the join code system seems to put out your ip even on a private world and that is a little concerning that there is no way to change that fact

also i have a 2nd question, can anybody just admin themselves on a server at anytime?? how does that work im so confused i feel like

[spiral bluff]

I built mine in AWS on an EC2 instance. So the IP is an AWS Public IP instead of my home IP address. A cloud hosted solution would use something other than your own Public IP.

[final current]

Not without a 3rd-party host, a VPN with port forwarding, a remote reverse proxy, or other form of tunelling. While players don't directly connect with you in Crossplay, the server's external IP address still gets used as an identifier for the server's relay.

[proven niche]

So, just a quick question floating around in the back of my mind... If you set up your Window's Firewall properly, how likely is it that you could still get hacked by someone getting your IP address from the Valheim server that you're running? On a scale of 1-10, what would that be?

Oh, and also, if someone set up a public Valheim server and invites players to join, does his server's -logfile capture and record the IP addresses of the players joining, or even attempting to join?

[final current]

Your average home server host is going to be behind a router with NAT, which prevents anything outside your forwarded ports being exposed. If some outside party who's not your friend wants to do more, you could expect a port scan and some fingerprint attempts or vulnerability exploit attempts on other ports that are open. That port scan is hitting your router instead of your server, so it's really a matter of what you've exposed on that router.

All that goes out the window if you use the router's DMZ feature to expose a server… at that point, you better hope your're not running some old or otherwise vulnerable services or have a good OS firewall configuration.

[proven niche]

Ok, so the short version of that sound's like, if you haven't turned on your router's DMZ feature, and are forwarding your ports and letting your router act as a sort of 'pre-firewall' device, then running a server and/or joining one isn't really any more risky then basically just turning on the PC.

Oh, and would using one of the free internet tunneling apps make a huge difference in how exposed you were?

[final current]

Yeah, pretty much. At that point, if your router itself is secure, you are only as vulnerable as Valheim Dedicated Server and the Steamworks networking is, because that would be their way in if any.

Free tunneling… I'm sure there's some risk from the provider themselves, but in theory, should give you the kind of privacy you'd expect from your own NAT with the added bonus of being another IP address. If you were hosting a direct/Steam Valheim Server, you'd need to make sure the tunnel includes UDP port forwarding. With Crossplay, it's all outbound+return traffic.

[proven niche]

Thanks. That's good info. 🍻

[final current]

They'll see join attempts. In a Steam server, they'll see the attempting joiner's Steam64ID. In a Crossplay server they'll see the attempting joiner's PlayFab player ID, but they won't see player IP addresses in the logs whether using Steam or Crossplay backend.

At some point, I think the server may have logged IP addresses in Steam/direct backend mode, but if so, it doesn't do that in the latest versions. Both Steam and Crossplay backends try to make most administrative actions you'd want to take not need to rely on IP addressing and just use player IDs for privilege escalation or banning.

Finding a remote peer's IP might be handy if you suspect they're using Valheim Dedicated Server or the Steam query port to DOS you or otherwise attack you at a non-gaming level. If they really want to, a Steam server operator can determine player IP addresses based on the UDP traffic coming in. With a typical home setup, all of those IPs will actually be the server operator's router (that's NAT doing its thing), and the router's own administration tools would need to be used to determine the real external IP address of the players.

[proven niche]

That's encouraging. Thanks, again. 🙂

[civic bolt]

hello can the dedicated server can be play online with friends?

[final current]

Definitely. It's the best use for it. Both the in-game server and dedicated server are hosted by you though, and not by the developer or publisher.

When you install the dedicated server, there will be a PDF manual included in the base directory. This will have some hints on operation

[civic bolt]

okay thanks

because i cant seems to invite them is it because the port should not be a localshost:****?

[civic bolt]

i tried following the PDF but seems my friends cant join

[proven niche]

Localhost means only you can join and only when you're on the same PC as the server.

If you have -crossplay in the start .bat to support Xbox players then you and others can join with the Join Code in the server log file.

If you don't have -crossplay there then you need to forward the server's ports in your router and others join with your internet IP address and you join with the server's internal IP address.

[civic bolt]

got it thanks. able to search about it earlier but sadly i just learn my IP was under CGNAT

[proven niche]

Then, contact your internet provider and ask to re removed from CGNAT or consider renting a game server from a hosting Co.

[civic bolt]

that be my option just rent a game server

thanks for the advice

[final current]

3rd-party host may be your best option if your ISP refuses to give you an Internet IP address in the end, but I want to make sure you know some alternatives…

Is it one friend or multiple that you want to have join you? If just one friend and you both have the Steam version of the game, you can have your friend start the game and wait in the character selection screen, then use the Steam overlay or Steam's friends tab to invite them to play with you (using the in-game server instead of Dedicated Server). Sometimes Steam invites can facilitate communication over CGNAT in this way. Not always, but it's nice when it works.

You might also have luck with Crossplay on the dedicated server. It is a little slower, but if you choose a port that no one else in your CGNAT ISP is using for a game (e.g. -port 32456), you would give your friend(s) the join code that shows up in the logs and have them connect to the game using that.

[civic bolt]

we are group of 6-7 friends. dathost is good choice?

[proven niche]

We can't recommend specific server hosts in here. But, you could search and see if anything in here does come up for Dathost. Just in case...

[civic bolt]

okay thanks and my bad sorry

[final current]

Not a problem at all. It's a common question 🙂

[civic bolt]

our in game server became a bit slower and we are now around ashland. and we decided to switch on a dedicated server.

btw thanks for the suggestions

[proven niche]

You're very welcome. Good luck with the new server! Have fun with it! 😄

[tall citrus]

I'm trying to host a private dedicated server using my pc, the command prompt window displays that the game server is connected and when I look in the server browser in the join game tab in valheim it recognizes the server too. When I connect it doesn't prompt me for a password and just returns me to the login screen saying failed to connect

I have portforwarded and added inbound and outbound rules for 2456-2458

Server is also password protected too. Any suggestions on how to trouble shoot?\

[plain trellis]

Have you done anything about the permittedlist.txt or bannedlist.txt?

[proven niche]

Make sure that your port forwarding is working as you expect. Double check the server's internal IP address and the port assigned in it's start .bat file.

The port forwarding in your router needs to use the UDP protocol to forward the server's ports. Some routers are a bit fussy and work better when you forward the ports individually rather than a range. For default settings, forward the assigned port and one port higher seperately. The server only needs the two ports rather than the three noted in the inst. manual.

[plain trellis]

If they are blank, that is ok.

[tall citrus]

they're both empty actually, was wondering if that was somewhat the reason.

[plain trellis]

Empty are good

[tall citrus]

ill give individual port forwarding a go, thanks for that

[final current]

Are you using Crossplay or not?

And how did you add the server to the Join Game tab? Loopback IP, LAN IP, external IP, domain name, Community tab, or Crossplay join/invite code?

[proven niche]

You may only be able to use the server's internal IP address from the same LAN as the server is on. Because some home routers prevent 'loopback' connections and so you wouldn't be able to connect with the WAN IP address.

[tall citrus]

Crossplay was enabled as part of the default batch command and didn't remove it just so I can get the server up and connectable before changing anything else

[tall citrus]

I wouldn't have thought so as I assumed it would have been the same for minecraft, but I'll give localhost a go too

[tall citrus]

currently trying to connect directly through the IP and port displayed on the command prompt window

[final current]

Try the join code from the display instead. It's a little easier to use with Crossplay.

[proven niche]

With -crossplay, port forwarding isn't used at all. Everyone including the server and all players no matter the location go directly to an MS playfab network relay station in order to get back and forth to the server. In that case, the Join Code is used.

[tall citrus]

i see, the join game tab does recognize my IP without the port being in the add textbox, still not getting a password prompt though...

the join game tab even detects that a password should be entered.

I don't really see this join game code in my comand prompt, only the IP weirdly. Is there a specific section of text I can look for for the code?

[proven niche]

IIRC, it appears in the server's start up command window, and it's log file, if it's creating one with the -logfile option, as well as in your game menu once you get in the game with it.

[tall citrus]

what's even weirder is that when I try use the steam server browser it prompts me to enter the password, and I still get failed to connect after trying to connect.

No change in the command prompt window at all in both ways of connecting, unsure whether text would be outputted when a user tries to connect

[proven niche]

I'd use the start up option -logfile \path\ServerLog.txt to have the server create a log. It'll come in handy later as well as show the Join Code at start up. The server will rewrite the log at every start up.

[proven niche]

Again, I'm not sure, but I believe that the server isn't aware of any connection attempt that doesn't give you a password prompt. The attempt just hasn't reached the server at all.

[tall citrus]

the log file only has New session server that has join code, now 0 players and no code, its taunting me haha

[tall citrus]

this feels like the issue to me too, not too sure how to change that annoyingly

[proven niche]

Restarting the server should produce a new log file with the current Join Code at the bottom of the file.

[tall citrus]

it might be worth mentioning that I am running the server on a pc and playing the game to connect on another pc

[proven niche]

That's fine. I assumed that. 🙂

Have you considered running the server without crossplay? You'd be unable to have Xbox players join in that case. But you could join with the IP addresses and without any Join Code.

[tall citrus]

ill give that a go now, don't see why not

[proven niche]

Without crossplay, you'd want to use the server's internal IP address, since you're on the same LAN.

[tall citrus]

that... worked.

so crossplay enabled caused the prompt to not display...

glad to know that all the setup but that was configured properly haha. Still confused why the join code never displayed with crossplay enabled

[proven niche]

Awesome! Looks like you're in business! Crossplay tends to be problematic in a number of ways. You're better off without it.

[tall citrus]

fair enough, works for me so thats amazing. thank you all for suggesting fixes

[final current]

Feel free to attach logs from one of your Crossplay runs to a post here if you want to troubleshoot further. If you're running Linux, Crossplay requires libpulse (including glib-mainloop support) and libatomic. If the server is running on Windows or Windows Server, the server will need the MSVC C++ runtime libraries installed.

Also note that Crossplay will have issues if you had an old instance running on a different PC in your house, but using the same port. It effectively only allows one server instance per port, per instance ID, per household (or per ISP subnet if your ISP uses CGNAT)

[tall citrus]

im not surprised if the problem is because the runtime libraries aren't installed. the build and installment of windows is as bare as possible

[proven niche]

Did you see in the news where MS is laying off people in it's Xbox division? I wonder if that console is a dying platform now.

[final current]

Sounds likely then. Deep in the logs on a Crossplay run you might find a hint about it when it tries to load the PlayFab Party libs. You can grab the X64 (x86_64) version from this table https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-microsoft-visual-c-redistributable-version . It's not currently distributed with the game or dedicated server.

[woeful pagoda]

Ayoo, i just download valheim today with friend and we want play. but i don't know why the game say imossible to connect tnext try in 20secondes...

and i search how can i make dedicated server to play, can someone help me/teach me ??

[final current]

We will need to know a bit more information. When it says "impossible to connect", how are you trying to connect? And is the server the in-game server or the dedicated server?

As for getting started with Dedicated Server, when you install it, there will be a PDF manual in the root of the installation folder that gives some idea on how to use it. If you want some more help with it, just let us know:

• Whether your dedicated server would be on Linux, macOS, or Windows
• Whether your dedicated server is on the same PC as your Valheim game/client
• How knowledgable you are on computers and networking.

[woeful pagoda]

i can't juste create online game, so i think's i need to create dedicated server but i don't know how

[final current]

Can you attach your Player.log in here right after you see that message?
It looks like you are running Microsoft Windows. If so, you can find it at %USERPROFILE%\AppData\LocalLow\IronGate\Valheim\Player.log
You can remove private information if you'd like.

[proven niche]

Your message is saying:

Connecting to backend services. Connection failed. Please check that you are connected to the internet. Try again in 23 seconds.

You need to be connected to the internet to start your game.

[woeful pagoda]

im connected to internet

[proven niche]

But your game can't fnd the internet. Is your Firewall blocking it? Try logging into your Steam acct. and then reverify your game files and then start the game.

And you can turn off your Firewall for a minute, try starting the game, and see if that's the problem. (Don't forget to turn your Firewall back on after letting the game communicate through it.)

Your game is a legal copy purchased through Steam, yes?

[final current]

It's the PlayFab auth that's failing in that message. That's why I'm looking for a Player.log, @woeful pagoda

[spare hazel]

Sorry to butt in, but may I ask you if it is acceptable to use the escape construct ^ to break line between server startup parameters in start_headless_server.bat,
or is it only acceptable to strictly write hyphenated flags on a single line with valheim_server?

[final current]

If cmd.exe or Microsoft Command is your batch interpreter, then breaking up the line like that is fine.

Valheim Dedicated server will never see those if their syntax is correct; Dedicated Server just gets a list of passed in arguments, regardless of how your batch file was constructed.

https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-xp/bb490954(v=technet.10) is the closest thing to documentation on the command interpreter that still exists unfortunately.

[spare hazel]

I followed your link - unpleasantly remembered what color my passport is, eh. But thank you very much for your answer! And to the guys from IronGate, for the opportunity to buy their wonderful game even in Mordor. From me and my wife - with big respect.

Sorry to butt in, but I didn't know Frodo had a computer. Let alone a passport. I've gotta get on line more...

[rose galleon]

hello i added my self to adminlist.txt and i have admin but when i execute a command like fly and i get ’fly’ is ont valid in the current context how do i fix this

[final current]

You would need to activate the devcommands context if you haven't already. That said, I don't believe vanilla Valheim will let you use that one while connected to a dedicated server. If this is the case, https://thunderstore.io/c/valheim/p/JereKuusela/Server_devcommands/ is a popular mod that can be installed client-side to enable it.

[rose galleon]

that means i dont need to install it on the server ?

[final current]

Not for flying, no, you don't need to install it on the server

[rose galleon]

ok thanks

[spare hazel]

Strangely, I can't find a modifier to enable Fire Hazards in the PDF manual. Is this even possible for dedicated servers?
Just in case, I'm attaching my .bat (only functional part of it), I'd be very grateful if you'd take a look and kick me for my mistakes

[knotty oracle]

Probably because it's a global key, not a modifier.

[spare hazel]

So something like -setkey fire won't work?

[knotty oracle]

That would do it, I believe.

[spare hazel]

Yeap Its works)

[gilded sparrow]

hi

Can i create a dedicated server where all my buddies are admins, meaning they can use 'devcommands' followed by 'debugmode' console commands?

[plain trellis]

They have to use the mod ServerCommands to be able to do that. And you need to update your Adminlist.txt for the server.

[gilded sparrow]

Cheers! i had a feeling it could only be done with a mod, but figured i’d double check on Discord just to be sure 🙂

[final current]

If you're not using any other modifiers/keys and your primary use case is to enable building, vanilla unmodded Valheim Dedicated Server allows admins to setworldpreset Hammer
It effectively sets these keys globally for all players:

• NoBuildCost
• PassiveMobs
• EventRate 0

Then it can be reverted with setworldpreset Default.

[gilded sparrow]

Thanks a lot mate - this is BIG!

[final current]

My only complaint is that NoBuildCost disables resource drops from enemies and hammer reclamation

[gilded sparrow]

As long there is no build cost, i think we will survive 😄

Honestly, the devs should really put more effort into this and let us build and move freely

[lofty edge]

Hey all, I've been trying to put together a dedicated valheim server for a bit now and I have been running into several issues. I have followed several guides but I have not been able to connect to a server instance other than one that is on my local machine

[snow topaz]

#1024264966712340510

[lofty edge]

thanks

[final current]

As in you've had trouble connecting to your own instance using its external IP or join code or that you've had issues connecting to another player's server?

If it's either of those problems, you're in the right place 😀

[lofty edge]

The first one but its both internal and external. Just a little more background. I am trying to run the valheim server off a Ubuntu VM on my gaming server. I first tried a docker container, than I tried steamcmd. I also tried a Windows VM.

I was only able to make it work by using the dedicated server inside steam on the host machine.

Are there any recommended guides for installing a valheim server on a ubuntu?

I always get to the part where the server is running but I can never connect to it. Ports on the firewall are open and on the router

[final current]

Cool, well, we can start with the Linux VM. Are you starting these server attempts with Crossplay support or no?

[lofty edge]

I am starting it with Crossplay support but I have no need for it. I just never disabled it

[final current]

Well, keeping Crossplay enabled will make connectivity testing difficult. It disables inbound access to the service. You would only be able to access it using the join code or your true external IP address. It works by making outbound communication to a relay first and all game clients communicate with that same relay on the Internet.

On the bright side, it means that any form of networking that gives you outbound Internet access with stateful return traffic allowed will "just work". So, easy setup with out of the box docker bridge network or your VMs, and they will work behind a NAT without any port forwarding rules whatsoever.

It's a bit slow and unreliable though, as every leg must communicate via the relay and then it hits a relay again to get to another leg, including the server's leg.

[lofty edge]

Gotcha. I will try disabling that.
Currently I am in the middle of a thunderstorm storm so I am unable to troubleshoot.

[final current]

Understood. Maybe the same one that's about to roll over me.

[pseudo surge]

Hey, Im trying to host a dedicated server. Ive ran into an issue where removing -crosplay allows me and my PC friends to connect, but obviously this limits our Xbox gamers. Keeping crossplay enabled makes it so none of us can connect. Any help?

[pseudo surge]

Any help?

[viscid thistle]

sorry, but idk how to help u

if it's a modded server, take out the mods, otherwise i cant help. sorry :(

[pseudo surge]

Nah, its just simply not letting anyone connect with the -crossplay tag enabled

[final current]

Sure, how is everyone connecting to it? LAN IP address? Internet IP address? Domain name? Join code?
If they just used their existing favorites/recents entry, they would likely need to add a new entry for the server after changing network backends.

[pseudo surge]

No this is a fresh dedicated server

I am hosting it on my home server and I've sent them the external IP and password to the server

Ive double and triple checked that my ports are open

[final current]

Just making sure, does your "external IP" start with 100 or 192? Re ports open, that won't matter with Crossplay as players don't connect to you directly in Crossplay mode.

Regardless of the IP, using the join code from your server logs will be the most reliable way of addressing the server from other clients in Crossplay mode, especially the Xbox. In my experience it also results in a more stable recents entry. And if you don't see a join code in your server log, that's more indicative of why Crossplay isn't working for you.

[pseudo surge]

External IP starts with 75 :D

[final current]

Good deal

[pseudo surge]

So, does the join code allow them to join even if the crossplay tag is not set?

Because when I have -crossplay in my batch file, it doesn't allow anyone to connect at all

[final current]

You would only see a join code when -crossplay is supplied. It exists explicitly for Crossplay networking.

[pseudo surge]

Gotcha

Then that brings me to the original issue. I couldnt get anyone to connect when -crossplay was enabled

[final current]

But you were giving them your external IP address. Have you tried with join code instead?

[pseudo surge]

No- I couldn't join either

Nobody on PC or Xbox could get a connection

For instance, I would try and I'd just be met with "Failed to connect"

[final current]

So try with the join code instead. Is a join code present in your log when -crossplay is supplied?

[pseudo surge]

Would that show somewhere in the server logs?

Let me save and shut down the server and then restart it with -crossplay enabled

[final current]

It will appear near the end of the startup sequence, typically

[pseudo surge]

Understood

[final current]

And if it doesn't, that gives us a good clue

[pseudo surge]

What am I looking for? Just "Join code" or is it some other moniker

[final current]

Yeah, "join code", usually on a line about PlayFab stuff. Sometimes "invite code".

[pseudo surge]

New session server 'Server Name Redacted because its inappropriately funny' that has join code, now 0 player(s)

[final current]

Cool, is it a number like "join code ______, now 0 players"?

[pseudo surge]

It'sjust blank

[final current]

Cool, that explains further why it might not be working. It's not establishing a PlayFab Party relay. Is your server on Linux, macOS, or Windows?

[pseudo surge]

So happy that youre helping me narrow down the issue!

My server is hosted on a Windows VM using Proxmox

Cool, if it's a pretty fresh install, you likely haven't had a program force installation of the MSVC C++ runtime libraries yet. You can grab a copy of the X64 (x86_64) version here:

After installation, start the server again and see if you get a join code this time around

[pseudo surge]

It is a barebones install just straight from the windows media creation

Ill go ahead and download these now! Thank you

Alright- Server's coming back up now

Still no join code, though

Should I restart the VM?

ooh wait wait wait

Wait we got a join code. I just didnt look hard enough

It works! im able to join

Ill send the code to my Xbox friends and see what they can do

Thank you so much. Can I buy you a coffee or anything?

[final current]

Rockin. Join Code is how I'd recommend connecting to the Crossplay server, though you can still give people the external IP address if you really want.

Note the join code will change if you restart the server or if it takes too long to communicate with Microsoft's relay server and you can get the new one from your server logs or a player can see it after pressing Esc. A recent or favorites entry in the server list created using a join code should continue to work despite any restarts/code changes.

[pseudo surge]

Awesome!

[final current]

No need, but I appreciate the coffee offer 🙂

[pseudo surge]

I did send them the external IP just in case but Ive made sure to send the join code

Valheim is not compatible with PS5 yet, right?

[final current]

Right, not yet. Theoretically possible with the game engine, so never-say-never there.

[pseudo surge]

It'd be a great addition for sure

[hollow dirge]

Hi all.
I've been playing valheim for a while on xbox. I have a niece who plays steam (she just got the game). We tried playing together tonight. When I sent her a game invite, it took her to a Microsoft page to buy that version of valheim, it wouldnt let her join me using a join code either. When I tried to join her gane with a code, it worked fine.

How can I get it so she can join my game?

[plain trellis]

Xbox players I play together with, can join my server. They have GamePass (to be able to play online), that could be the reason. And my server has crossplay enabled.

[final current]

#valheim-help message

[plain trellis]

I'm using ServerDevCommands 1.97 on client side, and testing it on my dedicated server, but the command
find pickable_stonerock 10
doesn't work. It does on the same seed in solo.
Does others here experience the same?

[gilded lintel]

can you make a dedicated server with a world i already have?

[plain trellis]

Yes. Your make sure your server config refer to the same world name, and take your solo world and past it into the server World folder. And boot up the server.

[final current]

find command in particular requires server-side modding if you haven't already. You should be able to use client-side findtp on objects your client has encountered during the session in the meantime if you only care about the nearest

[final current]

If you run into trouble, let us know whether your client is on Linux, macOS, or Windows, and then same for your server and whether you're using a cloud-synced world or a locally-managed one.

[plain trellis]

I totally forgot about findtp command. I'll try that out.
Thank you.

[gilded lintel]

Okay

[hushed relic]

my power cut today, and not only did the world roll back, it rolled back hours even after i had manually saved, and i checked and there have been no autosaves in 3 days, nothing has changed? ubuntu server

any help is appreciated

[final current]

Sorry that's happening to you 😦 Are you using an all-in-one container with its own backup infrastructure like lloesche's or mbround's?

Regardless, I would go ahead and back up worlds_local manually somewhere before you proceed further just in case things get worse before they get better.

If not running in a container, any changes to the system user you're running the game as or to the -savedir argument since it was running prior to the power outage. Checked the modified dates of everything in worlds_local in just in case there's something newer that's not as obvious (including the .old.(fwl|db) pair)

[hushed relic]

i am running it as is through steam with the ./run_server.sh or whatever, i didnt set any save dir, worlds_local had all the out of date files. I ended up moving it to my root directory and running it sudo and it is backing up again so well see if it continues

[final current]

Alright. Assuming you've done something like ls -lt in both the normal user's ~/.config/unity3d/IronGate/Valheim/worlds_local, and /root/.config/… to look for it, if you had been running directly with Steam, you would also want to check ~/.var/app/com.valvesoftware.Steam/.config/unity3d/IronGate/Valheim/worlds_local

And following the power outage, it may not hurt to run your file system's checking or repair tools. e.g. if this is XFS, you could do xfs_repair -n to see if it would do anything, then perform a real run if applicable. Recovered files would be put in the lost+found directory.

If ext4, e2fsck -n would be the equivalent.

[hushed relic]

No such file or directory

ive had issues with valheim failing to save many times and the lack of logs is irritating

its 50/50 weather it autosaves at all and it only conistsntly saves properly when shutdown

idk why this game / linux has so much trouble saving its slightly irritating

[knotty oracle]

I doubt weather has anything to do with it, though it is rather warm right now.

[hushed relic]

bro looks like a grammar nazi

[plain trellis]

So findtp didn't work either for me. My server does run BepInEx, but ServerDevCommands are only run on my client. Shouldn't that work? Other admin commands I've tested, are working.
Are other admins using ServerDevCommands on dedicated servers, able to run
find pickable_stonerock 10?
If so, something is off in my end, and I need to investigate what other mod could cause this issue for me.

[knotty oracle]

Probably best to ask about mod issues in #mods-discussion or #mods-issues

[plain trellis]

Maybe. I see devcommands on dedicated servers as a gray area. So I ask first here, where the core of dedicated server-knowledge are.

[knotty oracle]

Devcommands on servers are not possible in vanilla which pretty much makes it a mod issue.

[plain trellis]

Again, true. Doesn't change how I see this. Or I could run around posting the same stuff in every channel that might be relevant. Choose your poison.

[knotty oracle]

No, I think most would prefer you to just prefer you to post in the one correct channel.

[final current]

findtp will only work for what your client session knows about/has encountered and yes, find requires server-side Server Devcommands or similar mod (usually in conjunction with client mod). https://github.com/JereKuusela/valheim-dev/blob/main/README.md#server-devcommands for the doc

[snow topaz]

i have a quiz for all of you dedicated players, what shows I'm using devcommands??

[final current]

Do you already know the answer? I'm not seeing it

[final current]

But if you're asking how other players on the server know, they can see it if they type /stats into chat if I recall

[knotty oracle]

No, I'm fairly sure she knows, but I'm really not seeing anything obvious. Health is OK for zero food, stamina looks good, damage from the axe is fine.

[snow topaz]

i do know

[snow topaz]

okay, the thing proving i used dev commands is the stone pickaxe in my 8th inventory slot being only accessible by spawning it in, why it looks familiar is actually because it's the sprite that appears when leveling up your pickaxe skill. that one was pretty tricky I'll admit [giving the answer because it's been about 2 hours ago, there will be more, don't worry]

[knotty oracle]

Aaah, I didn't even twig. Nice one.

[snow topaz]

Thx

[final current]

You had nice items as clues to show it wasn't axe nor hoe. I should have picked up on that

[snow topaz]

yup

[plain trellis]

Played over 1500h of Valheim since release in EA, and STILL learning new stuff!
I love it! 🙂
Thank you for the insight on findtp
I'll look deeper into the documentation on Github.
Thank you.

[candid spire]

Ok. Question here, on the start_headless_server.bat file, where it says -world "dedicated", can i change the dedicated to a seed?

[knotty oracle]

No, you change it to the name of your world that you want to load.

[final current]

If you're looking to use a specific seed, I think you would need to use the game/client to create the world with the specific seed then migrate it to your server.

[candid spire]

I've tried that, but it never works as in. It's not the same map

[final current]

Well, if you want to go that route again, just let us know the steps you've taken and what OS your game client and the OS your server are running under.

[candid spire]

Current released game client. Windows 11. I go onto my pc, create a game using the seed i want, play, save, copy the save file to usb, transfer save file to save folder on server pc. I set up the headless file and start server. Ive done it the way i was told the steps are about 10 times and it has never used the map i created and saved.

[final current]

Alrighty. And your server is on Windows 11 as well? And are you specifying a -savedir <savedir> in the server arguments?

[candid spire]

Yes and yes

[candid spire]

So i was actually looking to see if there was another way

[final current]

There is not, but we can get this working I'm sure. So you saved the world, closed the game, and you copied the <world name>.fwl and <world name>.db files onto the USB?

[candid spire]

Yes. Im not currently home. Ill reply again when i do get home

[final current]

Sure, sounds good. When you do get home, take a look at that -savedir <savedir> argument. You'll want to put those files inside of <savedir>\worlds_local and if your savedir path ends with …\worlds_local, that would mean you would have a redundant path element …\worlds_local\worlds_local\<world name>.fwl effectively.

The -world <world name> world name argument value will need to match the world name in <world name>.fwl and <world name>.db file names and it's case sensitive. It's also sensitive to your file system's Unicode normalization rules if you're using any diacritical marks in the world name.

Of note, the -name <server name> argument doesn't matter for locating/using a world.

[candid spire]

Okay so I understand, so basically, my entire problem may just be me, not putting putting it cool in the correct place that i'm supposed to

[final current]

Hopefully it's something simple like that

[fiery summit]

@final current you are the smart guy around here for dedicated servers?

[final current]

hehe, there are a few subject matter experts around, I've just been noisy lately. If you've got a query, best to just ask away and someone who knows will chime in.

[fiery summit]

well, going to start with the simplest: i have the dedicated server downloaded, and running when i play, have others join so we can work together, but on a windows update, or restarting the server, things go missing, the join code changes, etc

getting very frustrated that we get so far and then have to reset to start again. THe latest time, i copied all the dedicated server files, put them in a different spot, so that when teh game corrupted (my house was missing but bed icon still there) it would not retrieve the data

[final current]

Alright. The join code changing is pretty normal. It will change whenever the server restarts or detects bad connectivity to Microsoft's servers. Even through code changes, players' existing recent/favorites entries for the server should continue to work.

When you say Windows update is one of the causes of the world reset, is the server running Windows as well? Is it the same PC you are running a game client on? And are you running any mods?

[fiery summit]

that is correct. vanilla dedicated server ont eh same pc i play on. in attempts in the past, i have tried restoring the character, the world, etc inside valheim as well. and I am not getting anything. However, I would like to mod it a bit to say turn off raids and turn down aggression. Is there a place to add those to a server doc? or in game switch somewhere?

[final current]

Running the server on the same PC as the game client can be pretty dangerous from a world management perspective, especially if there has ever been a cloud-synced world with the same name as the one you play with on the server (which doesn't use cloud syncing).
If you're not already using the -savedir <savedir path> argument to the server, I would recommend creating a new directory for the server's state files so there is no conflict with the game client. You would place the <world name>.fwl and <world name>.db pair in the <savedir path>\worlds_local subdir. If you're using adminlist, whitelist, or bans, you'll want to copy those into <savedir path> as well.

[candid spire]

The same headless-server file you modify to be able to run the dedicated server.. just like the -crossplay, you will put i think its -modify raids none. Ill see if i can find the page that has these commands

[final current]

There will be some basic variants of the modifiers mentioned in the PDF manual that comes with the Dedicated Server.

[candid spire]

https://www.valheimgame.com/support/a-guide-to-dedicated-servers/ at the bottom of the page here.. has the commands to modify the server

[final current]

It's also worth asking how you are restarting your server when you do it manually (and how you launch it in the first place).

[fiery summit]

ok, gonna to be the dumb kid in the class a moment. where do i write that command line "-savedir"?

[final current]

In your copy of the .bat file that you launch the server with.

There will be a line in there that launches the server itself. The same line where your -world <world name> argument lives.

[fiery summit]

ok, so just adding another "-command" like i do for server name, world name, etc

I launch the server typically through steam, or clicking the Dedicated Server icont on my desktop

[fiery summit]

awesome! TY! just to clarify, raids none is simple, but to move all materials through a portal is casual? death penalty casual is basically no penalty?

[candid spire]

Yes.. but if you set a preset like setting it to hard, or harder or something like that, that will take precedent

[final current]

Thanks, and how are you closing it when it comes time for a Windows Update or other restart required?

BTW, if you take a look at the manual, it recommends making a copy of your .bat file and launching it manually (e.g. by double-clicking in Windows Explorer) instead of going through Steam. That way you can be sure that a game update isn't overwriting your .bat file. There have also been issues with license-tracking in the past where it can sometimes not let you use either the server or the game if they are both launched through Steam.

[candid spire]

This is what i do.. i updated my .bat file and sent it to my desktop.. when i need to launch it .. just double click

[fiery summit]

i will do this. thanks!

[final current]

Cool, and how are you closing it in your current way of things? The safest way to close it is Ctrl+C in the console it's running in; in just about every OS, that will trigger Dedicated Server's final save to disk activity. You will see OnApplicationQuit mentioned in the output or log before a final save and a noisy memory stats dump. If Dedicated Server is killed instead with immediate termination, you can end up losing up to 30 minutes of your changes to terrain, buildings, dropped items, and chest inventory.

[fiery summit]

ok, i may have done something wrong. i updated the server_head, moved it to the desktop and wont launch... am i missing something?

Or did you mean make a shortcut link?

[candid spire]

right click on the file, send to desktop

[fiery summit]

Like a shortcut, correct?

[final current]

I don't remember the contents of the Windows .bat file, but you need to add a line before the server start line to cd to the server installation directory if you've copied the .bat file elsewhere.

[fallen lily]

Can someone pls tell me how do I use the mods from r2modman to my valheim dedicated server?

[final current]

Give #mods-discussion a try. We try to focus on the vanilla dedicated server operation in this channel and you'll find more knowledgable hands in there.

[fallen lily]

Alright, thanks!

Actually I have other question, if I am hosting the dedicated server is there a way to save the world's progress along with our characters?

Without using the code:
-saveinterval

on this file: start_headless_server.bat

[final current]

If you don't set that argument, it uses a default save interval, which I think is every 30 mins. An admin-listed player should be able to trigger a save from the Esc menu, a console save command or possibly a /save chat command (I might remember that wrong). The server will also save when given an INT or TERM signal in Linux and likely in the next macOS dedicated server releases. In Windows and Windows Server, Ctrl+C in the Command console will do something similar before exiting.

Those apply to the world save though. Unless you're using a mod for it, it's up to players' game clients to save their character state (including map state) to the .fch file and I don't remember how often that happens or how to trigger it manually if there's a way.

[fallen lily]

I seee, okay thanks!

[chrome cypress]

i have a question

about a server i used to have.

[final current]

Go for it

[chrome cypress]

Soi made a dedicated server on my PC for me and coworkers. we played on it etc. i moved states new ip etc. my computer had to be everything but hard reset pretty much. i can no longer find the game files or anything to get that world back or the server. to the best of my knowledge. is there any other ways to get it back. i believe i still have the ip address and or world name.

[final current]

Linux or Windows PC?

[chrome cypress]

Windows 11

[final current]

Then the first place to check is %USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds_local

Look for a <world name>.fwl and <world name>.db file pair whose .db file has some size to it and a modified date matching your expectations when it was last played. Note that if your file manager is Windows Explorer, it won't display the .db extension in its default configuration.

[chrome cypress]

thats unfortunate. it has 1kb. thanks for your time though @final current

[final current]

How about the timestamped backups in there?

[chrome cypress]

both from today. i think it got wiped when my pc kinda crashed

[final current]

And any chance you had run it as a different Windows system user or had run it using a Microsoft Account then but not now or vice versa?

Or is there a chance you had been serving it using the in-game server instead of Valheim Dedicated Server?

[chrome cypress]

no chance on the account. i used the steam VDS

[spiral bluff]

I'm seeing an issue on a Linux hosted Valheim server where sometimes when we load into our main base and go to drop items into a cart, smelter, or other holder, the items don't end up in the destination and disappear from the inventory. Is anyone else seeing this type of an issue later on in their playthrough?

It seems lag related where it queues up the deposit item step, takes the item out of the inventory, and when the deposit item times out, the item doesn't return to the inventory or destination

[final current]

Yes, unfortunately it's not uncommon when there's lag. Typically restarting the game/clients is enough to get passed it. I hope you didn't lose something too valuable 😦

[spiral bluff]

Much appreciated Justin, thank you. Any idea if this is an issue that may get solved in the full release or already in a mod?

[final current]

Alright, then the next thing to check would be your old batch file, PowerShell script, or however you used to launch the server and see if you'd used the -savedir <savedir path> argument to the server launch, if so, you would want to look in <savedir path>\worlds_local instead.

If you had used the same PC for both the game client and the dedicated server, this is a dangerous setup for world management, and it's possible that cloud-syncing overwrote the world. You can check for a staged copy of the world in these folders if that were the case:

• %USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds (not worlds_local)
• %ProgramFiles(x86)%\Steam\userdata\<steam user ID>\892970\remote\worlds

[chrome cypress]

hmm ok

ok i found it. how do i recover it and add it to a none server set up? just my local

[final current]

Great. Back up the .fwl and .db pair for safe-keeping first. It's easy to mess things up in the next steps.

Then check for blank/empty/fresh world with the same conflicting name already being used by the game. I would recommend using the in-game Start Game flow for this. Looking at the worlds list, if you see one with the same world name that you might have accidentally created recently. If you're sure this is the bad/blank/empty/fresh one, then consider deleting it here with the UI.

Then close the game and copy the good/old/filled <world name>.fwl and <world name>.db file pair from your backup to %USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds_local if you're restoring from one of the autobackups, you can rename them to remove .old or any of the timestamping that might be included.

Start the game. Take a look at the worlds list and make sure the world you copied is there and has the floppy disk icon indicating it is locally-managed and not cloud-synced. At this point, you can optionally switch the world to being cloud-synced and Valheim will remove it from worlds_local and put it somewhere else for syncing with Steam cloud. Whether you keep it locally-managed or cloud-synced, it should be safe to play in this world with the game client now.

If you decide to go with Dedicated Server again in the future on the same PC, consider creating a separate -savedir <…> to put the world in to avoid conflicting with the game/client.

[chrome cypress]

so i had 9000 kb. on the .db but notihing on fwl. is that a problem for windows?

[final current]

The .fwl corresponding to the .db file should be very small, but it shouldn't be 0 bytes

[chrome cypress]

its at 1kb

[final current]

Cool. If it has the same base file name as the .db from the same dir then that sounds good.

[chrome cypress]

Is the size of the file related to how much of the map is discovered/unlocked?

[plain trellis]

You might also take a look at your Steam Cloud storage for Valheim:
https://store.steampowered.com/account/remotestorageapp?appid=892970&index=0

[final current]

In the .db file, yes, terrain changes, buildings, chests, dropped items, etc.

The .fwl only stores fundamental metadata like world name, seed, world modifiers and keys, so stays small

[chrome cypress]

mmk. ill try again

[chrome cypress]

guess its gone. thats unfortunate. if those are the only places. that file wasn't it.

[final current]

Was there nothing in the 9MB .db world, or was it just an earlier version? Did you get a chance to check https://store.steampowered.com/account/remotestorageapp?appid=892970&index=0 per Gyro's suggestion?

[chrome cypress]

it was a map. but it had nothing done to it. not the save i was looking for. and yeah its not on there.

[candid spire]

what is the -preset for turning the fire system?

[final current]

If you're wanting Fire Hazards, it's -setkey Fire. If you're setting any presets via the command line, you'll want to make sure the -setkey arguments come after the presets lest they be overridden.

[candid spire]

gotcha.. thank you

[candid spire]

-crossplay -preset hard -modifier Resources more -setkey fire so this is good

[final current]

Looks good to me

[candid spire]

cool

thank you

[final current]

Sorry :/ Is it only your one user subdirectory in the C:\Users directory?

[fiery summit]

Is the command line in s the server bat for mods -modifiers? -modify? or something else?

[knotty oracle]

As per the manual -modifier

[fiery summit]

ok, and if i change the command line in the current server i have going, it resets everything? @knotty oracle

[final current]

If you change the world name in your -world … argument to a world that doesn't exist yet, you will "reset" in that it will generate a new world with that new name.

If you set a -preset … it will reset any modifiers or server keys you had set in prior starts or had previously saved to the world or had set in earlier arguments to the same launch. Your gameplay progression keys should persist though.

[fiery summit]

i think you missed the point. I attempted to add modifiers, but there was a typo, so if i fix the typo top get the modifier, will i lose the progress i made in the world. Only thing that changes is the command -modifier

[final current]

Unless that typo affected your world name, there should not be a reset from adding a -modifier that hadn't been successfully applied before. If worried, though, certainly make a backup of your .fwl/.db world files pair.

I explicitly mentioned preset on the off-chance you were including one in your modifiers. Sorry if it seemed like I missed your point, I just wanted to cover all bases I could think of 😦

[main flume]

Does anyone here use Gportal and know how to white list ... If you fr don't know then please don't respond.

Ex- "in the text of white listing it says add players from steam like this STEAM_STEAM64" <-- that doesn't work I've tried... And the YouTube video also doesn't work. Because they don't say which Id to use either the steam name or the steam friend id I honestly can't tell

[knotty oracle]

Use the Steam number.

[main flume]

You have used Gportal and know that is what is used?

[knotty oracle]

No, but that's how the Whitelist works. Nothing to do with host.

[main flume]

Thank you

[maiden pendant]

i havent bought the game yet, was just wondering if theres public servers like ark? that i could join

[proven niche]

Yes, there are. You can see them in the #1024264966712340510 channel here.

[maiden pendant]

ah ty

[frank elk]

I have a friend who cant specifically connect to a server we rented out. Everyone else can join but its only him. He already verified and reinstalled valheim and everything but still no dice

any recommendations?

[plain trellis]

Check the client and server logs, to dial down what could be the reason. Server using Crossplay? How does you friend try to connect?
Edit: Yeah. Posting in multiple channels. Fun...

[mild gust]

any active valheim server with chill and coold people to play along ?

[final current]

Take a gander at #1024264966712340510

[mild gust]

i did but servers have no info

hi!

i dont see any active information of new server with chill players to play

do you know any server @final current ?

[knotty oracle]

#1024264966712340510 remains the best place to find servers.

chat gpt sums it up pretty well https://chatgpt.com/share/68785585-ba6c-8005-96d7-c3862ebf49b0

if you can connect on lan but not from outside, I would check port forwarding of 2456-2458 from server to router

also make sure those ports are not firewalled off

I'm going to have to disagree. I'm not seeing anything in ChatGPT's answer that is relevant to Evard's situation. They already mentioned that other players are playing successfully. With the network version check finishing in that log, connectivity appears to be established, so the answers about port forwarding and NAT aren't applicable. You can try for yourself against their query port and see it responds. Based on IP range, I'm guessing professional host. There is just about nothing useful in the ChatGPT response outside of "share the logs".

[final current]

Thanks for sharing the log, I'm assuming coming from the Player.log of the person having the issue? It seems early communication is working, then later failing, which is common when a security intermediate steps in, so my first checklist would be:

• Make sure they aren't using an Internet security suite while playing. If they are, see if they can whitelist outbound traffic to UDP ports 20543 and 20544
• If they're using a VPN, have them turn it off while playing.
• If their router has UDP flood protection or similar security features, encourage them to disable it.
• If their router has QoS or traffic shaping, have them try a round with it off.
• It's a long shot, but lowering their Steam ping frequency can sometimes help if they have a low-CPU router or one with overzealous security. Steam Settings (Preferences… on macOS) / In Game / MORE / Server browser pings/minute
  and reduce it from the default.
• If they're in a country with high-surveillance or high-filtration of International traffic, they could try a VPN if they aren't already using one, alternatively one of the IP-layer accelerators like CloudFlare Warp.

Hello guys idk if i'm in the good chanel but i have a issues with my world , me and my brother played on it last night and ngl , the map load , everything load but not the constructions made , before i solves that by loading a backup made before we leave , and it always come back to normal , but this time , all saves from 3am today (when we leave and saved ) to 3 days ago all are gone , map have logo of what we did , base , boss , where we goes and else , loot fine , but base construction is all gone , tamed lox gone , and i have no idea if this can be fix or not , i really don't want to go back 3 days ago and i'm trash in informatics for solve that by myself i'm too dumb for that

[final current]

Strange. Is your Dedicated Server running on the same PC that hosts the game/client maybe? Or have you possibly been running out of hard drive space?

If you're having to do this every time (did I get that right?), I also have to ask how you're exiting the Dedicated Server when you're done? And is this on Linux, macOS, or Windows?

[midnight trench]

space is good , the dedicated ig it's on my pc so same , we are all on windows , and i just let the server save + /save 2 time for be SURE and after that disconnected and don't close the game instantly

but before i was able to get back the construction by getting back the backup_restore by the /save , but this time all base gone , but everything is good just constructions and tamed animal are gone

but i'm still located in my base

in the good biome , good place , just there is Nothing when i spawn

(i used gpt for maybe know what happend i mean it's an informatic programs so he should know Better than me ) and it globaly say it could be or a problem with steamcloud or a corrupted backup that wipes one or more saves , but i have no idea if this is right or not i'm not into this work for know if it's actually the case or not and how to solve it

[plain trellis]

First; Your character remembers pr seed what coordinates it was log out on. So that is stored in the Character files.
From what you're sharing here, I guess that you share your world from your Valheim client, started by your normal Steam client.
You talked about checking backups. Was that world_local or in steam cloud? You need to check what storage solution, you're using, by checking the World list in Valheim.
My guess is that, for some reason, you start up your world now 3 days later, and your .db are reset to at some earlier versions.
Have a look at the your Steam Cloud for Valheim, and see if one of the backups there can help you.
https://store.steampowered.com/account/remotestorageapp?appid=892970&index=0

[midnight trench]

so basicly in the steam cloud the only save i have just before we left is the one at 2Am we left at like 3:4am , and all other's backup are the one when i connected trying to figure out what happend with my world so prob whitout construction

[plain trellis]

When you're manually saving in Esc menu, you overwrite the last save. So saving multiple times, will not create more saves, just overwrite the last autosave.

[midnight trench]

mhh can you accept the private message and ig it's easier to show than explainning bc for my part i'm lost asf ngl

[plain trellis]

Thanks, but no. If I'm correct, that this is a Steam solo world you're sharing, then this is the wrong channel. This is for players with question about their personally private dedicated servers, running on dedicated hardware.

[midnight trench]

I Said it at the start that I might be in the wrong Chanel but it was the only that seem good for this, and I have a server but I didn't checked at all on how they work

[plain trellis]

If you have a dedicated server running on the same hardware you play regular Steam game on, and didn't pay attention to create a dedicate-folder-structure, to make sure your dedicated server worlds are separate from your Steam solo world, you will have issues where Steam and your dedicate server will conflict on how to store and maintain proper world backup-structure. Especially if you're using the same world names in both "systems".
So are you on dedicated server (a .bat file to start it, and list data like world name, ports, password, etc), or did you start up Valheim, as if you would play solo, and chose to "Start Server" on an existing solo world in the Valheim "Select World" window?

[midnight trench]

Ig I use the normal thing, like just start the game get on the dedicated I created then just start the server, but I have steam valheim dedicated server too but no idea how they work and if I can put my map on it or else or how to use it anyways

[plain trellis]

How did you create your dedicated server? And how do you access it?

[midnight trench]

How it was create I don't really remember or I created a solo world or it was already there I forgot, but for the accès I just start the server, and put a password, cross-platform active, but ig that's the normal one, but the server is named dedicated and has a world map logo since I never called a world dedicated

[plain trellis]

And that is not a dedicated server. That is a solo-world you offer to share with others, and you must be online for others to join.

In this channel we discuss dedicated servers, running on dedicated hardware /PC, on Linux, Windows, on VM or in Docker. A world that is always online (as long as the server are turned on), and you as owner, don't have to be logged in, for others to access the world.
You're having issues with regular Steam, and for some reason, are having a conflict with your world files, that Valheim are loading for you.
I don't know why your world wasn't saved when you log out last time, but maybe people in #valheim-help might have some suggestions?

[midnight trench]

Valheim help isn't for gameplay question? 🤔

[tall creek]

I'm unsure whether to ask this question in this channel or in Steam Bugs or Valheim Help.

Yesterday I managed to connect to a dedicated server, but today I can't connect to any servers. The game tries to connect, but before I can enter my password, it says the connection failed. I did a clean install of the game, logged out of Steam and back in, restarted my PC, turned my modem off and on again... basically, I've tried everything, but nothing.

[final current]

Given it sounds client-side, I would:

1. Take a look at the Player.log just after one of the failed attempts to see if there's anything obvious. Feel free to remove private information then attach a Player.log to #valheim-help if you want a second opinion.
2. Check network permissions. You mention PC, so I'm assuming running Windows, but if macOS or Linux, let us know. In Windows, Control Panel, enter Windows Defender Firewall, on the left: "Allow an app or feature through Windows Defender Firewall", locate Steam and Valheim and make sure they have permissions to use networking as needed.
3. If it's specific servers that you had added before to favorites, but the server operator switched the networking backend (e.g. Steam/direct vs Crossplay), then consider deleting the favorites entry and re-adding it. Even if not using favorites, you can try Add Server for the previously-working server.
4. If you're running any kind of Internet security suite, forward proxy, or VPN, consider disabling it and trying to connect again as a test. Same goes for DNS proxies like Pi-hole.
5. If you're in a country with government intervening with access to certain sites, note that there might be a national block preventing you from moving further. Crossplay servers require the game client to query Microsoft's servers in the United States before connecting you to the server's more localized relay, for example.

[tall creek]

I'll take immediate action and update you. Thanks.

[tall creek]

Sorry, where I can find the Player log?

[final current]

Are you on Linux, macOS, or Windows?

[tall creek]

Windows.

[final current]

%USERPROFILE%\AppData\LocalLow\IronGate\Valheim\Player.log
It will be overwritten every time you restart the game client.
You can also find a shortcut to it in the game itself in the background of the main menu when you start the game.

[tall creek]

Can be this?

I added the game to the firewall list since it wasn't there, but yesterday it still connected. I don't know what changed today.

[final current]

Did it help anything?

[tall creek]

Nope.

[final current]

Yes, though it doesn't tell you the underlying cause. The timeout can be an issue connecting to Valve's servers or an issue connecting to the server itself. I assume you still have Steam running while trying to connect?
And you have no one else playing Valheim using your Steam account at the same time?
You've tried disabling any VPN software, Internet security suites, etc?

Yes of course, Steam is active in the background when I launch the game and no one else uses my account.

Alright. If you want someone else here to attempt connect to make sure the server is actually up, you're welcome to DM me the IP or domain name.

[final current]

I was able to connect, @tall creek. Which unfortunately doesn't help figure this out.

[tall creek]

Bad news... for me. Thank you so much for replying anyway.

[pale horizon]

Hi everyone, when I delete -crossplay 0 from my headless server file and boot the server it seems like the server gets stuck. Is there a way to remove it as I dont want the server to go through Playfab if possible

[final current]

-crossplay argument doesn't take a supplementary value so the 0 was probably being ignored or confusing things.

Either way, what are you seeing in the logs where it's stuck? And what makes you think it's stuck? Ideally, you can attach your log from start-to-stuck here. You can omit or obfuscate anything you deem private like usernames and IP addresses.

Note that when you remove Crossplay, players will directly connect to you, so all aspects of IT networking for routing Internet traffic to/from the server will be up to you.

[pale horizon]

Nevermind, I am just an idiot!

[final current]

All good, glad you got it working

[snow topaz]

True

[fiery summit]

mornin. I turned on passive mobs on my dedicated server and want to reverse it. I thought eh command was -removekey passivemobs but hasnt done anything. am I missing something?

[final current]

Heh, this one is a little bit of a pain as there isn't a removal argument. Two ways you could go about it that don't involve moving the world around:

• If you don't have any other specific modifiers or server keys you need:
  • You can pass -resetmodifiers or -preset Default on one launch to set things back as they were
  • An admin player can use setworldpreset Default in the console.
• If you don't mind your character getting a cheater stat, an admin player can run devcommands in the console to enable that context then removekey PassiveMobs. This way gives you a bit more precision.

Both are doable without mods.

[fiery summit]

Thanks, i went tried devcommands and it didnt seem to work, so i had to do the preset.

[final current]

devcommands is a little weird with vanilla client on Dedicated Server. You won't get any feedback from the server in the console to know that setkey or removekey worked.

[tall creek]

@final current Hi, I think I've figured out the problem and I'm posting it here so it might help someone else. It seems my ISP enabled CGNAT without my knowledge. I'll contact them tomorrow to have it disabled.

[final current]

Alrighty, cool deal. That usually doesn't matter for outbound connections to other servers, but if getting a real public IP address helps the problem, definitely let us know. That would be good/interesting info.

[tall creek]

I thought I'd found a solution, but it was only partial. After testing the line, I discovered I had this major limitation that blocked many ports.

In fact, CGNET strongly blocks incoming connections.

[final current]

Yes, it definitely prevents inbound port-forwarding.

[tall creek]

I will keep you updated after I speak to them.

[elfin coral]

@urban olive sorry for the out of the blue ping, but I'm having some issues trying to get valheim dedicated server to run via fex. I have fex installed, and successfully installed steam and the valheim dedicated server apps, but when trying to actually run the dedicated server, it fails to preload libparty.so. It can preload the other plugins that are in the same folder, but fails to preload libparty.so. Perhaps you can point me in the right direction? I'm running ubuntu server 24.04.2 lts

[final current]

Make sure you have your system's libpulse, libpulse-mainloop-glib and libatomic either available/installed or under emulation for libparty to use

That's assuming you want to host a Crossplay server. You can avoid all of that if you only want Steam/direct connections.

[elfin coral]

Can you be more specific about what exactly I need to have installed? Trying to Google libpulse I get half a dozen different ones

[final current]

I don't know fex well, but libparty needs those libraries.

The Debian (and I'm assuming Ubuntu) packages are libatomic1, libpulse0, libpulse-mainloop-glib0. I don't know if fex will wrap or make them available if you install them in your base system or if you'd have to install x86_64 versions and emulate them.

If you don't start the server with -crossplay, it should let you proceed without libparty working, but only Steam players will be able to connect to you and the IT networking will be up to you instead of Microsoft

[elfin coral]

Here's what I have installed

[final current]

Alrighty, you'll want to check for libatomic as well. I see x86_64 libpulse in the emulator's dirs but not the glib mainloop supplement

But maybe those are wrappers created on startup and you just didn't have the mainloop lib installed last time you started it?

[elfin coral]

I checked with sudo apt install, all 3 of those libraries are already latest version, according to apt

[final current]

On host system or with your emulator? It looks like the emulator has a way to chroot in to install the x86_64 versions: https://wiki.fex-emu.com/index.php/Development:Setting_up_RootFS#Chrooting_in_to_rootfs_with_FEX-Emu_Rootfs

Someone who actually knows FEX welcome to chime in if they know an easier way.

[elfin coral]

What would be the libparty package name, if I want to install it with apt?

[elfin coral]

On host system

[final current]

x86_64 libparty.so actually ships with Valheim and it should be picked up automatically by the game whether emulated or not, though I think you can download it from the PlayFab Party GitHub releases page if you prefer to bring your own. If it fails to load it usually means one of those dependency libs is missing.

Re host system answer, then I would take a look at that doc page I linked. Once chrooted via the emulator, you may be able to sudo apt install the missing x86_64 packages.

See how your emulator RootFS in your screenshot is missing the x86_64 version of the glib mainloop lib, and you can check for libatomic as well

[elfin coral]

The chroot thing makes no sense to me, but I'm not really a Linux person. I daily drive windows and am never going to switch, because Linux is one headache after another. I'm only bothering with it right now because it's a Raspberry pi, and I don't windows will run on it.

[final current]

Sure, though you would have the same problem on Windows on the Pi, needing to use an x86_64 emulator.

The chroot steps are basically to give you a command prompt that is acting like your emulated system is your host system so that when you install something with apt, it is installing the x86_64 version instead of the arm64/aarch64 version, and installing it in your emulator's root (/) instead of your real host's root.

Once you're done installing things in the chroot, you would break out of it to be back acting on your real system.

There are probably some scripts that do most of the work for you for running Valheim Dedicated Server in box64 instead of FEX if you aren't set on FEX. Though if Dragon was helping you with FEX maybe they can help get you past the finish line.

[elfin coral]

I must be stupid, I'm trying to read the site you linked and I still don't understand how to chroot in and out

It's a really poorly written article

[final current]

Agreed, it is pretty sparse on steps, yeah. And you're not stupid. I would look for that unbreak_chroot.sh script and run it from your shell/terminal

If you get that far and install missing libs, you can then exit from the chroot, followed by running that break script

Gotta head to bed. Good luck!

[elfin coral]

Seems I don't have the unbreak_chroot.sh file anywhere

[elfin coral]

When you wake up, I managed to get the libparty.so figured out. I don't have an unbreak_chroot.sh, but I do have a chroot.py file, which only has three commands: unbreak, break, and chroot. Seems I needed to install another package to use the chroot.py, patchelf. After I installed that, I was able to apt install libpulse-mainloop-glib0, and it seems I also needed to update libatomic1 to the latest version. After that was done, it now preloads libparty.so no problem.

[young smelt]

Any chance I could rope someone into creating a Valheim headless server page for tldr? https://github.com/tldr-pages/tldr/issues/17125

[final current]

Nice, glad you got it working!

[elfin coral]

well, "working", lol

now i have to get the thing actually running persistently

ok! world is running properly! and i can still use ssh to do stuff. i should probably make it a service...but using "nohup ./script.sh &" works well enough for me and it's not too much of a bother to run

[dense goblet]

How does using the dedicated server through Steam work? Is it only active as long as I am logged into the world? Or will it run when I am offline? Does my computer just have to be on? Will it shut off when I shut my computer down?

[final current]

Steam or SteamCMD are great for installing it but aren't needed to launch it. In fact, the PDF manual that comes with it suggests making your own copy of the startup script template and running that however you want to. Internet access is required when you first launch it though the server will happilly survive Internet connectivity drops (your non-loopback and non-LAN players would experience disconnects though).

It is "running" as long as the dedicated server process itself is running, though gameplay time progression pauses if there are no players connected.

As for computer shutdown behavior, that depends on how you're running it. If you're managing it with your system's process/daemon manager, like systemd or OpenRC then it will definitely shut down when your computer does, but you will want to give it a nice long termination grace period to give it time to save the latest version of your world. If you're on a Mac, note the current macOS version of the server doesn't perform graceful shutdown with save (will be fixed in a future update).

[elfin coral]

having to keep the device running the dedicated server process on is why i'm going to the trouble of getting it running on a raspberry pi 5. a raspberry pi 5 consumes far less power than my desktop pc.

[dense goblet]

Yeah, I have an old laptop with TrueNAS on it set up but TrueNAS does not have an internal app for Valheim like it does for other games so there are a lot more steps to getting a Valheim server set up on it. I've wated so many videos on setting up a Valheim server on it but they look so complicated and make me feel like I will have to like write/modify code and I'm fairly afraid of messing it up lol

[elfin coral]

getting it running on truenas is definitely worth it in your case

and i doubt it's as complicated as getting it running on a raspberry pi

[dense goblet]

Yeah, I agree it would be worth it, I just dunno what I am doing lol I barely got the TrueNAS server up and running. Had a friend help me with the finishing parts since I didn't even know what port forwarding was until I asked for their help lol

[elfin coral]

you will have to do some port forwarding to get vds running properly

yeah, i'm making it into an acronym, because i don't want to type valheim dedicated server 50 times, lol

[dense goblet]

fair enough lol

[elfin coral]

but yeah, running vds does require some port forwarding and/or firewall editing no matter how you go about it

you can run it on your gaming pc, but you will have to port forward. or on a nas/other dedicated device. but you still need to port forward. or you can put it on a web hosting service, like a vps, but you will still need to screw around with firewalls and port forwarding

there's no escaping port forwarding for this

[final current]

Less of that needed if you use the Crossplay mode. In that mode, players don't directly connect to you, and both server and players communicate through a relay.

(but it's a bit slower/less reliable because of the relay)

[dense goblet]

Oh, im not worried about having to do port forwarding, I was just saying like, I was so green when I started that I didn't even know about port forwarding but most computer savvy ppl make it seem like it's as basic as findig your Start Menu lol

I defs wanna get it set up on my TrueNAS server eventually but it just seems so intimidating. I am also thinking I might just wait until Deep North is out so that I really only have to set it up once lol

[elfin coral]

as long as you don't sail anywhere near the deep north, you probably won't need to create a new world when the update comes out

[dense goblet]

Devs say it is always best to start a new world when new content is released for the best/most full experience

[elfin coral]

true...but they do make an effort to not make older worlds fully unplayable. the way it works is, new content isn't available on already explored chunks, but unexplored chunks get access to the new stuff

[dense goblet]

100% agree but I want that best experience and I am not worried about starting over. I love playing Valheim!

[final current]

For someone wanting to contribute, is there a target "environment" those tldrs are aiming for? Linux? Linux container runner? And should the author assume a particular process manager like systemd or try to stick to documenting the raw game server process?

[young smelt]

There are directories in the pages directory for different OS's. No need to assume anything past that, as long as there is a functioning command. And the purpose here is to document oneliners, not getting an autostarting environment

[minor moat]

any 1 have a server i can join

[wind mantle]

HI folks, I have a dedicated Valheim server I'm running in an unraid Docker. I had to restart my unRAID server the other night to do an update, and after restarting Valheim, the server seems to have wiped itself back to square 1

I had backups running... but it looks like it takes them every 30 or 60 minutes, and only seems to store the last 10 backups. So it seems like they may have over written itself. although I can't say for sure

I don't really play much anymore, but trying to run the server for friends.. So I dind't catch the problem until about 12 hours after it happenes. Any idea on how I may be able to restore the previous world? or am I totally boned at this point?

[final current]

Take a look through #1024264966712340510

[final current]

Whose image are you running? ich777's?

[wind mantle]

yeah ich777

installed via community apps in unraid. I've had this running for maybe a month or so without issues. I've done a few restarts before and didn't have this problem. But I'm not sure if Valheim docker updated when I did those restarts, I think thats what happened here (valheim docker updated when it restarted)

[final current]

OK, well, make sure your world name hasn't changed. If so, that's an easy answer and solution.

That image should give you two types of backups: dedicated server's built-in ones and the image's ones. I would take inventory and make your own backup copies of both just in case:

• Image-assisted should be in whatever dir is mounted at the container's /serverdata/serverfiles/Backups. I'm guessing these were the 30-minute ones you were talking about.
• Buillt-in ones should exist alongside the current/active .fwl/.db pair in whatever dir is mounted at the container's /serverdata/serverfiles/.config/unity3d/IronGate/Valheim and may have ones beyond the 10x 30m windows. It would also have the previous active pair if you had accidentally chosen a new world name.

If you supplied a SERVER_DIR env var, use that for the base path in the container to consider instead of /serverdata/serverfiles. I don't know Unraid's containers setup, but you'd have a either volume or bind mount of a host system's file system to the dir specified in SERVER_DIR, I'm guesssing in a config screen if not a manual docker/podman/lxc command.

[wind mantle]

Thanks! I didn't change any of the server config settings, so I don't think the name got accidently changed.
I just checked the .config/unity3d/irongate/valheim folder, but it looks like those may have been wiped somehow

so I see the .old files there, and the backups. but the incident happened around 1am on 7/20, these files seem to be modified after that

and with the really small file sizes...it doesn't look good

[elfin coral]

@final currentso...my first time running and playing, it seems my server ran into an issue. and it hasn't properly saved either, as when i restarted it loaded the same files it had initially. so that's a whole bunch of materials and stuff lost. anyway, here's the log of what happened

[final current]

No it doesn't look good sadly. I notice this volume is called cache_nvme though. Is it your Unraid cache disk? Reading the docs, it sounds like there is a daily mover script that moves files off there regularly.

[wind mantle]

Yeah, thats my unraid Cache array. but I don't have mover turned on (I know thats a semi common issue some have when using the mover)

I just keep all my docker info on the cache as I have plenty of space

I may have found a backup! As I have a utility that backs up my whole app data folder to my array every week. Looks like I just gotta restore that, which I haven't done before lol

[final current]

Looks like a permission issue at first glance. I would make sure you're running your start script as the ednakali Linux user. I would also check the permissions of what you copied, e.g.:

ls -la /home/ednakali/valheim_server/malasseziaworld

That dir itself (.) should have drwx… permissions and be owned by ednakali. The world files inside should at least be -rw… and owned by ednakali. If they aren't, you can:

sudo chown -R ednakali:ednakali /home/ednakali/valheim_server/malasseziaworld
chmod u+x /home/ednakali/valheim_server/malasseziaworld /home/ednakali/valheim_server/malasseziaworld/worlds_local
chmod -R u+rw /home/ednakali/valheim_server/malasseziaworld/worlds_local

The segmentation fault at the end of the log is worrying, hopefully it's related to the permissions issue and not a random occurrence due to emulator bug.

[wind mantle]

but I'm guessing if I can extract the .db and .fwl files from my backup, I can hopefully just put them back in that folder

[final current]

Good deal. Hopefully does the trick. Would be nice to know what happened to cause the total wipe in the first place.

[elfin coral]

so the permission issue can be solved by sudo or making my user admin or screwing around with permissions/ownership...

but the crash is more worrying for me. i'd want to avoid that in the future

[final current]

Definitely. You're the first person I've seen in here get vds working on FEX. If it occurs regularly even after fixing permissions, you might have to report it to the FEX devs. I wouldn't know where to start debugging a segfault within emulation.

If so, you might have better luck with box64/box32, which has a few more Valheim users, from what I can tell.

[elfin coral]

You're the first person I've seen in here get vds working on FEX
i find that surprising, given i'm all thumbs when it comes to working with linux in general, let alone figuring out emulation issues, lol

perhaps other people are just not so public about trying to get it running and have more success than me

@urban olive would definitely like your input on this whole thing, please

[final current]

I'm guessing you did this already, but If the cache is a cache pool for your array, you may want to double-check the array's equivalent location just in case the files ended up getting moved anyway by the upgrade or the minimum free space switchover.

[elfin coral]

ok...dir is owned by my user, but files are owned by root. and running as root throws the libparty.so error again. because i don't feel like fixing it for root...guess time to do some chowns

[final current]

Yep, some examples here: #dedicated-server message

[elfin coral]

-rw-r--r-- is correct for the .db and .fwl files, right?

[final current]

Yep, looks good for those assuming you're the owner.

[elfin coral]

yeah, i just took ownership of everything in malasseziaworld

btw...that name...is the name of a fungal infection, lol

[elfin coral]

@final currentwanna make sure, this is the id i need to put in admins.txt, right?

[final current]

With a Crossplay server, I think you'll want to check the log lines that say:

PlayFab socket with remote ID playfab/… received local Platform ID <player id>

where <player_id> is what you want to add, including the platform part like Steam_ if applicable.

[elfin coral]

i mean, i connected via ip:port from the steam version of the game

[final current]

That's fine, same thing I posted still applies. Even when using the IP/port, Valheim won't directly connect to a Crossplay server, and it'll use the PlayFab Party networking to make it happen through a relay. Any port forwarding won't even be used.

Re that log line, If you're in-game, it's also what you'd see for the connecting players when you press F2.

[elfin coral]

ok, i see, it appears a bit earlier

[final current]

yep, that's the one

[tall creek]

Hi @final current , I have an update on my issue. This afternoon I called my ISP and asked them to disable CGNAT, and although they denied it was there, they'll check it out within the next 48 hours. Meanwhile, with the help of a user, we discovered that by disabling crossplay and using ||Cloudflare WARP||, I can connect to the servers, so I'll have to look for servers without crossplay.

[steel pumice]

is it possible to get an FTP downloaded world from a third party site, uploaded into my normal game

i dont want to lose the world we all built

[final current]

Thanks for the update. I'll be curious on underlying cause. Many Russian ISPs already block Crossplay access now. Even outside of that, could be an ISP's anti-piracy shield gone wrong.

[final current]

Yes, assuming you got both the .fwl and corresponding .db file. Are you running the in-game server or Valheim Dedicated Server? And are you on Linux, macOS, or Windows?

[tall creek]

This is the policy of my current ISP, but I honestly don't care since I've been with them for years and they've only just implemented these restrictions. I think I'll switch since there are other ISPs that don't enforce these things at all.

[elfin coral]

@final currentso...the segfault happened again...

[final current]

That's a real bummer. What version of FEX are you on?

[elfin coral]

should be latest...iirc, i made sure to update it when trying to get libparty working

[final current]

I doubt you've done anything wrong at this point. I do see some fixes to clock_nanosleep where it crashed in FEX 2105 and a later fix in FEX 2305, but I'm guessing you're on a newer version than those. :/

[elfin coral]

at least now saves are working properly, so it should be minimal loss of stuff for players. i have it saving every 15 minutes, so it should minimize disruption

perhaps i'll see about writing a script to check if there's a process /bin/bash ./start_FunGal.sh running and automatically start it if it isn't there

[final current]

You could take it to the next level and do it the Ubuntu Server way. Ubuntu uses systemd for managing the boot up sequence and manage long-running processes. It's very similar to Windows Service Control Manager (SCM) if you're coming from Windows Server.

As root or via sudo, you would create a file at /etc/systemd/system/valheim.service that looks like:

[Unit]
Description=Valheim Dedicated Server
Wants=network.target
After=syslog.target network-online.target

[Service]
Type=simple
Restart=on-failure
RestartSec=10
User=ednakali
WorkingDirectory=/home/ednakali/valheim_server
ExecStart=/home/ednakali/valheim_server/start_FunGal.sh
TimeoutStopSec=40

[Install]
WantedBy=multi-user.target

replacing the WorkingDirectory and ExecStart values with the real ones
Then sudo systemctl daemon-reload to register the new file or after changing it.
sudo systemctl start valheim to start it any time
sudo systemctl stop valheim to stop it any time.
sudo systemctl enable valheim.service to make it auto-matically start on system boot without you having to start it.

[elfin coral]

but doesn't this only run at startup?

i want to restart it without restarting the whole pi

in any case, getting segfaults more frequently now...

[final current]

This would do that. It's part of systemd's process management, unrelated to boot sequence. The Restart=on-failure configuration above instructs it to auto-restart the underlying executable if it exited due to an error.

RestartSec=10 tells it to wait 10 seconds before starting anew, but you can make that whatever you want.

It's basically the ultimate nohup.

[elfin coral]

last two segfaults are both clock_nanosleep...

[elfin coral]

yeah, i'm on 2507...but it seems that's still an issue

[elfin coral]

@final current so... I went to the fex discord server... And one of the maintainers has an idea of what might be wrong and how to fix it, but implementing it will probably take a while. So a service seems to be my best bet

[final current]

Gotcha. Nice you were able to get in touch

[elfin coral]

And short save interval, so at least people don't lose too much progress. Even if that means more chances for crashes

Something like 10 minutes is probably best. 6 chances of crash per hour, but only 10 minutes of lost progress in the event of a crash

[elfin coral]

@final current btw, seems the chroot page is outdated. Yes, they've changed it from unbreak_chroot.sh and break_chroot.sh to chroot.py and just haven't updated the documentation yet.

[final current]

Good to know!

[elfin coral]

Just to put it out there, in case someone else needs to screw around with chroot on FEX-Emu:

1. cd to /.fex-emu/RootFS/Ubuntu_24_04/, which will probably be installed in /home/youruser/
2. Type ./chroot.py chroot
3. Proceed to use apt as you normally would, going through the whole rigamarole of apt update, apt install package, etc. Don't bother with adding sudo here, it's a. not needed and b. likely to cause errors you don't want to deal with
4. Type exit to properly exit from the chroot
5. That's it! You should be done.

Couple of notes:

1. chroot.py has a couple of other options besides just chroot. It also has unbreak and break. I haven't figured out how to properly use those, so for now I recommend sticking with just the chroot option.
2. I included Ubuntu_24_04 path because that's the version I have installed, but you will probably have a different distro installed. Therefore, replace Ubuntu_24_04 with the name and version of the os that you have installed

[pale horizon]

Hi all, just checking what the experienced ping of some people is when using a local server? On a local Server I get between 16 - 50 ms which seems way too high / inconsistent for local but maybe I am missing something

[final current]

Are you using the Crossplay backend or Steam/direct? How are you connecting to your local server? loopback IP, LAN IP, external IP, join code?

[pale horizon]

I am using Steam direct and joining with my local IP:2456

[elfin coral]

Are you connecting over wifi or ethernet?

Wifi typically has much higher ping

[pale horizon]

I am using Ethernet

[elfin coral]

Also, is the local server hosted on the same physical machine as the client or a different machine? If the latter, if either machine connects over Wi-Fi, it would explain why the ping is so high. If it's on the same machine, there's something waerd.

[pale horizon]

Its hosted on another Machine. I did an Iperf test and it is 0.024ms jitter and 0.39% packet loss. Maybe the packet loss is the issue?

[elfin coral]

Though, honestly, 50ms isn't that high in the grand scheme of things

[elfin coral]

And both machines connect via ethernet?

[pale horizon]

Yep both are and consistently hit 2.37Gbps between each other

[elfin coral]

Are there any additional devices between the two machines? Like server > switch > router > switch > client or something else like that?

[pale horizon]

It goes Server -> Router -> Switch -> PC

[elfin coral]

I suppose something between the router and the switch could be slowing down the ping...

@pale horizon try doing a tracert from the pc to the server

[pale horizon]

I just ran it and it is only one entry (no router for some reason) and all <1ms

[elfin coral]

What about ping? What does that show?

Might want to try actually connecting to the server while you have a packet sniffer like Wireshark or Fiddler4 running to see what valheim is doing when connecting to the server. Is valheim first connecting to steam over the internet for some reason, then back to your network and on to the local server?

[pale horizon]

Thats a good idea actually It definitely doesnt feel like it running local. I might try Unplugging from the internet on the router too and see what happens

[final current]

Local IP as in 192.168…?

[pale horizon]

Yep that is correct

[final current]

Is the client on the same subnet as the server or are there VLANs involved? Ideally the packets shouldn't even be touching the router, at least not the CPU part of it.

[elfin coral]

I imagine vlans would be involved since it's server > router > switch > pc

[pale horizon]

It is on the same subnet I believe. I havent set up any VLANs yet

This is the ping test with -n 100:

Valhiem was still varying from 16ms to 53ms

Actually a better question to ask, what is more reliable? Using the F2 console or the /ping command?

The F2 console has 0ms

[final current]

Might be normal for /ping. I'll check a Valheim to Dedicated Server over the same switch.

[pale horizon]

Thank you

[final current]

Yep, not just you. This is workstation ->10gbe->switch->2.5gbe->server ipvlan, short Cat 8 cables. Just slow app-level turnaround time for the RPC system.

[elfin coral]

Bit unrelated... But I hope the devs come out with a native aarch64 version of the vds, lol

[pale horizon]

Thanks Justin, I really appreciate that. At least I know its not myself being an idiot haha

Any ideas if I can reduce it further or just wait and see if its addressed?

[final current]

I agree, though it's pretty much in Unity's hands. They have a mysterious "call us for details" policy on their elusive arm64 engine for Linux. I've always speculated they had signed an arm64 exclusivity agreement with Qualcomm like Microsoft did at some point… but that's just speculation. If you have a Unity account, make sure to give your vote.

They have native arm64 dedicated server for macOS

[final current]

No good ideas beyond getting CPU with faster per-core base clock speed on either side. I am curious where the bottleneck is. Could be the Steamworks networking lib or its .Net wrapper or something in Valheim flooding some other RPC calls.

[elfin coral]

If I do it this way, I'll have to set a logfile flag rather than use nohup.out, right?

[elfin coral]

Far as I can tell, apple silicon isn't Qualcomm, it's tsmc

[final current]

You would skip nohup altogether. systemd will be the parent process or will defer it to the root/init instead of your shell interpreter being the parent. I would also recommend skipping the logfile argument. systemd's built in log management will use the stdout from vds.

journalctl -f -u valheim at any point to stream the logs as they come in. See journalctl --help for more.

[elfin coral]

I wouldn't want to stream them, though. I'd want to copy the file instead

[final current]

Yea, if they have or had exclusivity, it would be for Linux for the potential embedded and kiosk business.

[elfin coral]

Streaming is more cumbersome to me than simply copying a file

Idk if it's come through yet, but I don't enjoy running 50 commands in the cli to do something simple. Yes, I know I've chosen to deal with it to run the dedicated server on very little power draw, but I still want to minimize the amount of <redacted>ing around in the cli I have to do

I consider Linux borderline unusable for the average user because of all the <redacted>ing around in the cli you typically have to do, even when you have a full fledged desktop environment

[final current]

Sure, then drop the -f

journalctl -u valheim > ~/valheim_so_far.log
or
journalctl -u valheim --since yesterday > valheim-1day.log

With systemd, you shouldn't have a need to run a commands. It's there to manage processes for you, e.g. for less command typing. You can enable vds for system boot and leave it be.

[elfin coral]

I assume -u valheim is checking for user valheim?

[final current]

It's referring to the valheim service unit (i.e. when you named the file valheim.service)

[elfin coral]

Ah. So -u is for unit, not user

[final current]

Right. The user it runs as is configured in your .service file

[elfin coral]

I thought user because so far it's been user in commands I've used that have a -u flag(like pgrep, kill, etc)

[final current]

Understandable assumption

Basically when you apt get something that runs in the background in Ubuntu, systemd is what it's using for that in most cases. To see what's already running:

sudo systemctl list-units --type=service --state=active

Similar to running Services.msc in Windows

[final current]

I should mention specifically for copying files with no command writing (e.g. just using SFTP or rsync), systemd journald on Ubuntu uses /var/log/journal as the storage area for these, rotated according to disk space and the journald config.

Off to bed. Night!

[elfin coral]

doesn't automatically restart on segfault

[final current]

Did you get rid of any nohup or & in the script's launch of Valheim? In this case, you want systemd to own the process tree and be responsible for backgrounding it, otherwise it won't know when it crashed.

[elfin coral]

there never was either of those

all the nohup and & was done at the calling the script level

[final current]

Cool. If the .sh script is launching vds directly, maybe set -e somewhere before the vds launch to ensure the script exits with an error code (instead of continuing to a non-error close).

Alternatively you can do something like ./valheim-x86_64 -arguments … || exit 1
I personally prefer set -e as there's usually no point in continuing a script after an unexpected error.

[elfin coral]

i'm going to need more specific instructions on how to do the -e thing, lol

[final current]

Cool, sorry for the bad timing on my messages. Working atm. set -e is just a command you'd have on a line in your .sh script. Any statement after that line that ends in an error will cause the script itself to exit with an error at that point. From there, systemd will see the failure exit and do the restart thing.

Without set -e, if Dedicated Server closes with an error like the segfault, the script will just continue executing statements like everything is fine and exit with code 0 (success) and systemd will assume you meant to shut it down and won't bother to restart.

[final current]

https://www.gnu.org/software/bash/manual/bash.html#The-Set-Builtin-1 for the doc if you're curious to dive deeper

[young smelt]

@final current any info you need to create the tldr page?

[humble cloak]

I am using this egg configuration and running on docker.

https://github.com/pelican-eggs/games-steamcmd/blob/main/valheim/valheim_vanilla/egg-valheim.json

But when I set crossplay to 0, the server doesn't work at all. What am I missing?

[final current]

When you say doesn't work at all, what do you mean? It crashes? There is an error in the logs? It works but can't connect to it?

[humble cloak]

It works, console says it's running. There's no error and I can see it in the valheim server list. It's just that it won't connect.

[final current]

OK, to be clear, you're setting the ENABLE_CROSSPLAY Pelican env var to "0"? And when you say you can see it in the Valheim server list, are you talking about Favorites, Recent, or Community?

Note that when you disable Crossplay, it can take some time before your server's registration with Microsoft's servers expires, and during that time, game clients might still be attempting to connect via Microsoft's relays instead of directly connecting to your server over the Internet. You can check your game client's Player.log after a connection attempt to check if this is happening. In there, if you see a line for your IP like:

PlayFab lobby matching search filter 'string_key10 eq '<external ip>:<external port>' and string_key2 eq 'True'': …

that ends in something other than zero lobbies, it means it's still trying to connect to a Crossplay relay instead of direct connection and for external IP connectivity, you'll have to wait until the registration with Microsoft expires or you could use a different port.

A second note is that when Crossplay is disabled, all (successful) connections are directly made to your server. This means you'd be able to connect to your server via its LAN IP or even the loopback IP if your game client is on the same machine. It also means to successfully connect via your external IP address, all IT networking aspects of Internet routing are now up to you instead of Microsoft. You'll need to make sure your UDP port forwarding rules are working if using a typical NAT router for home use and you'll need to make sure your ISP isn't using CGNAT for your connection.

[final current]

I don't think it will be me, sorry, certainly not this week 😦

[humble cloak]

OK, to be clear, you're setting the ENABLE_CROSSPLAY Pelican env var to "0"?
Yes.

And when you say you can see it in the Valheim server list, are you talking about Favorites, Recent, or Community?
In join game, under recent, with the direct IP and (dedicated) description

I am in a VPS so the UDP ports are definitely open and not behind a CGNAT.

Sure, though the "lobby matching search filter" result part is the important one from the client's Player.log to know if the Crossplay registration is tripping you up.

[humble cloak]

It works now, with the crossplay set at 0. And I switched back the port numbers, which meant it took a while to expire the registration with Microsoft. Thanks!

[real timber]

Hi, I am running a dedicated server for valheim using the tool on steam, it's set up, stable and going well, I followed the instructions, I am having one issue though, even though I have crossplay enabled (i think) by having the "-crossplay" in the server .bat file, my friend on Xbox cannot seem to join us, and only gets failed to connect prompts rather than password, I don't see any activity on the server log when they attempt to join, and I can see that the server is connecting to the playfab backend correctly. (or so I think it is)

Coin for your thoughts?

[humble cloak]

Is there any server commands I can use to make in-game announcements?

[final current]

You are giving this Xbox player your join/invite code and it's the most up-to-date code from your server logs?

[real timber]

Yep!

[final current]

Everyone else is using the join code to connect? Or are they using external IP address?

There are countries and ISPs blocking access to the PlayFab Party relays needed to access a Crossplay server. If this player happens to be in Russia, that could be an issue.

They need to be signed in to Xbox Live, if I recall.

Otherwise, if they have control over their router, they should make sure UDP flood protection is off and could also try disabling traffic shaping or QoS if enabled.

If none of those things, MaCarBre has Xbox players run through the "Test NAT type" test mentioned here:
https://support.xbox.com/en-US/help/hardware-network/connect-network/xbox-one-nat-error
sometimes it can show useful errors for troubleshooting

[real timber]

They are using a mixture of the two, all are based in the UK, I will check the rest, thank you!

[final current]

The /s <message> chat command done as a player is your best bet in vanilla Valheim as far as I know. The dedicated server doesn't take any stdin console commands.

[humble cloak]

Does valheim plus or valheim bepinex have these options?

[plain trellis]

To my knowledge, Valheim (or any mods) have no way to do admin stuff like announcements. No RCon-like functions, only webhooks from server and out to example discord.

[sage nexus]

there is a mod or two that simulate a server originated message, but i cant recall which mod atm

[shrewd stone]

Hi, we rent a Valheim Server on hosthavoc.com and started with no portals, no map, double ressources, harder combat. We actived Valheim Plus later on.
After reaching mountain, we could not find a single dragon egg after several hours. I checked the map seed on valheim-map.world after that.
There are SO many things which should exist according to the seed viewer, but do not on our map. Beehives, whole structures of buildings, also we did not find a single troll cave while several are supposed to be there.

I guess there's no solution to fix our map, but does anybody know why this happened? :S

[proven niche]

Normally, you won't see things on your map until you've explored close to them and 'discovered' them. How is it that you've started your server with 'no map' and now are wondering why stuff isn't on your map? That's a little odd.

[shrewd stone]

I checked the seed on the valheim-map.world after we spent hours searching for dragon eggs

and then rechecking the locations it would show

the website has SO many points of interest which are just missing on our seed/map/whatever

[proven niche]

That site shows you where stuff will be located in your world. It doesn't mean that stuff will ever show up on your game map. And, the game doesn't always put some things in the same place each time it generates a new world from a particular seed. If it can't place something somewhere for whatever reason it can move on and find another place for it.

[shrewd stone]

i dont mean that it shows up on my ingame-map when i press M, in case i did not phrase that well

[plain trellis]

Take the seed and create a new solo world in your Steam, and check the map and logs

[shrewd stone]

did that a few seconds ago, all the POIs are correct there lol

[plain trellis]

So then your seed of this hosting partner of yours are rubbish

[shrewd stone]

well, back to hosting myself again i guess

[plain trellis]

It's much better to walk the extra mile, and have your own, personal dedicated server. Such hardware can be used to run servers for other games as well

[shrewd stone]

yea, done that several times already. just wanted to save some time and effort. so much for that lol
thanks anyways!
...and probably stay away from host-havoc :S

[elfin coral]

I mean, if you want a host, pick a vps host and spin up Linux, install steamcmd, then vds, then upload your own fwl and db files, edit the start_server.sh file, and go from there

Or, you can be nutty like me and get a Raspberry pi 5 16gb and do all of that on it instead. Though you'll also need to use an emulator like FEX-Emu or box64/box86

[final current]

Did you get the systemd restarts working, btw?

[elfin coral]

Yeah, it's automatically restarting it now

[final current]

nice

[final current]

I'd look into the Valheim Plus side of that as a possible culprit. The official mod hasn't been updated for a very long time, but maybe your host switched to one of the more-updated forks? Either way, mods are definitely sort of thing that can prevent biome feature/location generation. Sadly if they are the culprit, it can be difficult to re-generate features in the explored locations (without mods).

[elfin coral]

I'm not completely opposed to mods, I'm using some for the Sims 4, but I wouldn't consider them for Valheim

Too many downsides and not enough benefits

[fallen forum]

what is the best place to buy a didcated valheim server for about 6 people (maybe less) without mods?

I am going nuts. Trying to set a dedicated server up with the lloesche:Valheim image on a Windows system with Docker. Had it running on a NAS with Containers but need the power of the new server system I put together.
Is there anyone who can tell me what network settings to use for Docker itself?
I have the environment rules set up with the image but I cannot seem to reach it even though I have forwarded the ports inside the network but cannot reach it from the outside or the inside...

[final current]

Can you share your port forwarding arguments? As for networking, the default docker bridge network is fine. If you use a custom network, you might have a bit more setup. Fastest networking outside of host will be ipvlan, but I don't know how well that's supported in Windows.

And let us know if you're using Crossplay or not

[sly lodge]

Not using crossplay.

That standard bridge is just the thing. When Docker was on Synology that bridge was the 127xxx loop, but in the settings I cannot find anything like bridging or hosting. Whilst setting up from the image I did not get any choice in the matter either. So I figure it should be inside the settings of Docker itself, on how docker interacts with the network. But there my knowhow gets shaken up.

ports are only the ports just a higher number.

no IPs

[final current]

Can you give us your run command? Feel free to obfuscate the password if one is set

[sly lodge]

urh... I am not using commands, just the interface.,

[fiery summit]

I am on my dedicated server and trying to engage flying. I added my steamid to adminlist, turns -console on in valheim/steam, and typed devcommands. What am I missing?

[proven niche]

You also need the 'debugmode' command after the 'devcommands' command.

[fiery summit]

ok, and then after "debugmode" is engaged, what do i press?

[proven niche]

The "z" key. And you can set options in the ServerDevcommands mod to start off with an automatic devcommands and debugmode, if you want.

[fiery summit]

says debugmode is not valid in the current contaxt

[proven niche]

You need to have your 17 number SteamID in the adminlist file and load ServerDevcommands mod on your game. And adding it to the server as well opens up some additional commands.

[fiery summit]

i dont need additional commands, i just need flying for the purpose of flying temporarily

I already added my id to the adminlist

[proven niche]

It needs to be the adminlist on the server and you need to load the ServerDevcommands mod on your game.

[fiery summit]

wher do i find the server devcommands?

i found the adminling by searching inside my dedicated server folder

[proven niche]

https://thunderstore.io/c/valheim/p/JereKuusela/Server_devcommands/

[fiery summit]

... no idea how to mod anything...

[proven niche]

Download the r2modman mod manager from the thunderstore.io site, run it, and spend a few minutes exploring in it and learning how it works.

[fiery summit]

ok, i have r2 installed, the server devcommands, and used r2monman to run the "modded" server... went into the game, and still get the debug error @proven niche

[proven niche]

The r2modman app is installed on your game. Not the server. Right?

You ran the r2modman app, clicked on Online, found the ServerDevaommands and clicked on Download, right?

Then you clicked on Start Modded?

[fiery summit]

i clicked on the SERVER version, not Game

[proven niche]

Ah, there's the problem. When you start r2modman as it first starts up, you select the Valheim game and set it as default.

[fiery summit]

valheim game? not server?

[proven niche]

Right.

[fiery summit]

well, i thought eh point was to get the devcommands into the server so adminlist works

[proven niche]

Yes. When actually the point is to get the server to recognize you as an admin and allow your game to use it's ServerDevcommands mod to tell the server how to do what you want. In this case, to fly.

[fiery summit]

ok, so have to redownload r2modman?

[proven niche]

You have to install it on your game. Not on the server. If you did install it on the server, that's ok too. As long as it's running ok on the server it won't cause problems but it does first of all need to be running ok on your game.

[fiery summit]

ok, so can i change it from server to game without a re-install?

[proven niche]

No. You need to leave the server alone for a minute. Download and run r2modman on your game and use it there to load the ServerDevcommands mod on your game.

[fiery summit]

ok, finally got it! jeez that a alot of work for a short time use

[proven niche]

Yeah, maybe. But now a whole new world has opened up for you.

So many new paths you can follow, when you're ready. So many new things await you https://thunderstore.io/c/valheim/

But we can't really discuss mods in this channel. That's for the mods channels here. I almost forgot about that...

[fiery summit]

I dont want mods, i like playing vanilla. I just wanted flight fora temp reason and it is done. Thank you

i thought it had to be applied to the server side of things

[proven niche]

Yeah, mods are for only when you get tired of playing the vanilla game. You should always do that first, IMHO. But they do open up whole new stuff for the game when you're ready to move on.

[elfin coral]

You can't use devcommands on a dedicated server in vanilla. That's a local game only feature. If you want it on a server, you have to mod

[fiery summit]

Thank you for letting me know.

[silk jacinth]

Anybody know a good site for renting a valheim server

[elfin coral]

Whichever vps provider you like.

If I had to give a rec, I'd say ionos. But it's really up to you.

[fading imp]

I'm trying to apply to a server by the name of Joltheim

Thank you

[proven niche]

You may be able to find that server in the #1024264966712340510 channel here. This channel is only for help with setting up and/or maintaining your dedicated server.

[summer tide]

Does anyone know if there's a way to make the server characters mod work for a dual server setup, as in one mod pack cross server portals and I want people to create a new character for the servers but be able to use 1 character between the two servers??? I'm doing something a bit different. I'm trying to build a multiverse kind of thing

[plain trellis]

I'm not using Server Side character mod, but could you import each character to every server in your "mulitvers"? Would be some extra work, if someone new joins the 'vers, because admins must copy the new character to every world/server.

[summer tide]

I will look into that. Thanks for the advice

[sage nexus]

@summer tide ulvar like i said earlier/elsewhere: use a networking capable filesystem to access centrally stored character files. I guess somehting like NTP might be simplest, or maybe sshfs. idk; it will depend on weather or not the game/the mod can reliably access a file in that kind of context. I imagine that leaving one server and immediately entering another may cause an almost simultaneous write AND read, which might be a problem.

[midnight quest]

Hello all, I would like to know if there are any tips to create a new world on a lgsm valheim server? I would reset the actual server world without reinstall all server. Any tips?

[plain trellis]

I normally stop my server, then going into the folder where world files are saved, and clear that folder. When I boot up the server again, there is a new world created

[midnight quest]

where is the world file location? 😅

[plain trellis]

Your documentation for your server-setup will tell you that.

[rapid tusk]

Anyone else have probs with the dedicated server after the recent patch?
Mine was giving a certificate error today, then could not connect to PlayFab to register itself.
Applying the update seemed to solve the problem.

[final current]

Got a copy of the certificate error handy? No issues that I've heard of. If there had been any issue with your system clock though, that's one of the more common causes.

[gilded lintel]

You can port forward 2461-2463 if you so wanted a second self hosted server, right?

[final current]

Yes, you could forward your router's 2461 and 2462 to the game's default of 2456 & 2457, but ideally 2461 and 2462 are forwarded to your second server itself listening on 2461 and 2462 (with -port 2461 argument).

Note that if you're using Crossplay, your port forwarding is not used.

[gilded lintel]

Alright thank you

[gilded lintel]

What are these parts of the server config:

-nographics -batchmode

I never bothered learning about them

[final current]

Valheim passes them along to the underlying engine. They are for avoiding behaviors related to graphics and human interaction like you get on the main game client. They are documented here instead of the Dedicated Server manual:
https://docs.unity3d.com/2022.3/Documentation/Manual/PlayerCommandLineArguments.html

Valheim Dedicated Server now uses a server-specific runner (instead of Unity Player), so I suspect those arguments are no longer needed. They definitely don't seem to hurt though.

[gilded lintel]

I've been wanting the server to run smoother. It lags with just a few people when the machine is on fiber internet with an ethernet cable. On a network test the ping is 4 with 0ms jitter. The computer uses a 9800x3D and 128gb memory so I don't get why it lags

[final current]

Here's my usual checklist to run through: #dedicated-server message

[gilded lintel]

It's one of these:

The server or one of the players is using Wi-fi instead of Ethernet, fiber, or DAC, especially if they are first to an area
One of the players is using a VPN
Someone on the server or a player's network is saturating that connection, e.g. with bittorrent
The server is using the Iron Gate container builder/launcher, but with the older steamclient.so that ships with dedicated server.

But it's the server itself that's laggy

So I don't think it's player specific

It's the bittorrent thing or the irongate container

And I have no idea how to mess with either of those

[final current]

The server doesn't really do much except act as a relay for networking between players and a DB for terrain changes/chest inventory/dropped inventory. The first player to an area has their PC in charge of the final decision of almost everything happening in area, so if they are the slow leg it will seem like the server itself is being slow.

If you're using Iron Gate's container runner on the Linux version, just let us know the command line you use to start their script.

[gilded lintel]

I'm using windows

[gilded lintel]

Well that sucks

[final current]

Are you using Crossplay or not on the server?

[gilded lintel]

Crossplay is on the server

What if it wasn't on the server?

Someone once told me that there were some server performance mods. I guess I should try them

[final current]

That's going to be the most impactful thing you can change. Crossplay will amplify any lag problem, whether caused by the server, a player, or Microsoft's relay.

If all of your players are using the Steam version of the game, you're in a position to disable crossplay. It does require a bit more IT networking savvy as you would be responsible for making the server accessible to Internet traffic.

[gilded lintel]

One last thing, was it good to skip over 5 numbers for the port for hosting a second server like 2461-2463 or should I skip over 10 numbers?

I'm looking at the second server here and it doesn't seem to be port forwarded correctly

I already did the inbound and outbound rules on firewall

And this second one isn't crossplay

Not sure what I did wrong here

Now it just has a red X over it

[elfin coral]

you only really need to skip 2 numbers

[gilded lintel]

But I can connect locally

[elfin coral]

it's using port and port+1 only

[final current]

Without Crossplay, only public servers will convey metadata to the game client lobby views, and it will only show up for connection entries that use your public/external IP address.

The question mark or X for a loopback connection like that is normal. You should still be able to connect (and it will be nice and fast).

[gilded lintel]

So any friends won't have an issue?

[elfin coral]

it's not just firewall. it's router too. did you do that?

[gilded lintel]

@elfin coral

[final current]

If it's -public 1 and the UDP port forwarding is working, your friends should see the metadata/status. You can add an entry yourself for the public IP address (or a domain that points to the public IP) to see if it works. Just make sure to keep connecting using the loopback IP or LAN IP for your own activities to reduce strain on your router.

[gilded lintel]

So this kind of change?

[final current]

Yep, if you care about the metadata/status icon.

[elfin coral]

i mean, it's not really that much of a strain, is it?unless you have some bottom of the barrel cheap router...

[gilded lintel]

It didn't even work lol

Still starting question mark then to red x

I did save the file

[final current]

Cheap router with crappy CPU or expensive router with UDP flood protection. Neither of those enjoy the gameplay traffic, and especially don't enjoy the Steam lobbies query traffic.

[gilded lintel]

And restart server

-public 2?

[final current]

And you added <external IP>:2461 to your favorites list?

[elfin coral]

try using public ip for testing purposes

[elfin coral]

will have the same effect as -public 1. any non-zero value is treated the same

[final current]

1 is actually the only accepted value for turning it on there.

[elfin coral]

it's not 0=false, anything else=true?

[gilded lintel]

I guess I didn't port forward correctly? I have no idea what I did wrong though

I tried the bottom 2 and nothing

[elfin coral]

can you actually join either of the bottom 2?

[gilded lintel]

No

[final current]

Right, it's missing=true, 1=true, anything else=false

[elfin coral]

what's the port number in the start script?

[gilded lintel]

I can join this one no problem

I never locally join it anyway

[elfin coral]

hide the password, but show all of the script file?

[final current]

Yeah, that one is using Crossplay so it bypasses your port forwarding. Can you check your the reported WAN IPv4 address in your router's admin pages and see if it lines up with the 169… IP address you're using?

[final current]

looks good

[gilded lintel]

It's much different

[final current]

Does it start with 100?

[gilded lintel]

192.16 but more than that

I'm not saying the whole thing

[gilded lintel]

Starts with 192

[elfin coral]

you're looking at the wrong ip

that's the ip address internal to the network itself

[final current]

If it's saying 192.168… for the WAN IP (not the LAN IP), then you likely have what folks call double NAT.

[gilded lintel]

It matches

It's also 169.150.144.217

[final current]

OK good.

If your router's WAN port has the 169 address per the router's own admin portal, that's good, meaning you don't have CGNAT or double NAT. It does mean issue is likely in your forwarding rules then. Make sure you have the forwarding rule pointing to the LAN IP of this second server's ethernet adapter.

Make sure your Windows firewall isn't blocking the ports for the application either.

[gilded lintel]

Do you mind I just screenshare and you walk me through it?

[final current]

If you give me a minute, sure. I don't use Windows much so won't be able to help much on that side.

[gilded lintel]

Alright

[final current]

(resolved offline)

[elfin coral]

can you post a summary for others who may have a similar issue?

[final current]

Harken had done everything correctly by the time we hopped on a screenshare. Most likely the router model didn't support local route back to the WAN IP. I was able to connect remotely to the forwarded gameplay and query ports and get the server metadata/status, and geekstrom's server checker was also able to reach the query port.

So they may not be able to see what others see, but at least is able to still connect to the non-Crossplay server via loopback and LAN IPs, which is at the faster kernel or kernel+switch speed respectively.

[rapid tusk]

Sure do; I've run several servers over the past 2 years, and never had this error:

[final current]

Thanks for sharing! It's an interesting one. The certificate would have likely been on https://6e223.playfabapi.com/ which is used to register a Crossplay server.

If it wasn't coming back with a cert, your server either tried to hit it at an inopportune time (e.g. when Microsoft was performing maintenance) or a MITM "attack" prevented it from being served. This is common with an Internet security suite, or a router trying to present an Internet down page, parental guidance block page, Wi-fi captive portal after switching networks or other transparent proxy that presented itself instead of the real Microsoft server.

The later getaddrinfo() thread failed to start definitely reeks of down connection or Internet security suite interference instead of something on Microsoft's end.

[rapid tusk]

@final current Thanks for the great detail and insight; it is very much appreciated. I've asked around, and nobody else encountered that issue, so yes, I'm assuming it was a brief outage at an inopportune time for my server. It's a beefy full OS VM at a data center in Dallas on low latency high bandwidth pipes. I have control over the OS and access to the
firewall rules and logs, and did not see anything in logs for either. 😦

[humble cloak]

Is there a console command I can use to force a world save?

[final current]

Yes! If your player is admin-listed, they can issue the save console command.

[humble cloak]

Only from in-game? What about on the console itself?

[final current]

If you're talking about stdin from a terminal then no, the game accepts no commands over standard input. You can initiate a graceful shutdown, which causes a save. Ctrl+C to the hosting console on all platforms works for this, or SIGINT or SIGTERM on Linux and macOS (eventually).

[spark aspen]

any one know how to fix this?

[plain trellis]

Stop using the mod that produces the error.

[final current]

That looks good to me. Looks like it's generating a new world, unless that's not what you're wanting.

[elfin coral]

i think he's talking about those unity errors

[final current]

Me too. The missing "instance" is the progress bar for world generation that kicks off when the given world name is not found in <savedir>\worlds_local. While not intuitive, the message is completely normal. That instance is supposed to be missing in a headless server.

[plain trellis]

My apologies. I'll correct my comment.

[calm phoenix]

what is the purpose of this channel?

[knotty oracle]

For asking for help with setting up your own dedicated server.

[calm phoenix]

ohh, good, how do you turn on firehazard on one of these dedicated serers? I do not see an option for that

[knotty oracle]

Add -setkey fire to your batch file.

[calm phoenix]

that really didnt help much....

least it says it can be done

[final current]

Are you on Linux, macOS, or Windows? And are you using a specific container or game servers framework/dashboard?

[calm phoenix]

windows

[final current]

The install would have come with a PDF manual that is pretty helpful for getting started. The argument that Derek mentioned is included in there. The batch file he's referring to is your copy of the starting script.

[strong berry]

Hey, I was running, my dedicated server since a week, and we played a lot on it, but the pc that was running the server got full because of plex media things, and my whole user got wiped, I managed to get some data back with recuva, and when I launched my valheim game, the world was brand new and empty.
I have few ".old" files in the folder, I tried with some, some don't launch the game, some create a new world, and I managed to find one with data on it, but when I launched the world, all the building were here, but the terrain was not right, at all.
Which files have I to put as .db to recover my world ?
Thank you for the help !

[elfin coral]

Kind of an obvious question... Is this world modded?

@final current waerd question time because the answer isn't obvious to me: can I host vds on a device that doesn't directly connect to the internet, instead being accessed through a remote access vpn?

[proven niche]

Try to match up the .db and .fwl file pair by their day/time modified info.

[strong berry]

I did that and it worked ! Thank you

the game was indeed modded

[burnt widget]

hello, mind letting me join a server with u guys?

[elfin coral]

#1024264966712340510

[elfin coral]

This channel is for help with setting up hosting a vds, not for looking for servers to join. The above channel is where you find servers to join

[final current]

If the players are on the same virtual network as the server and joined using this network's IP addresses, that should work. The players and server would still need some kind of Internet access in order to call Steamworks APIs that facilitate player ID and lobby setup. It's OK if that Internet access is NATed and not direct.

There are some "Steam emulators" you could use to go the extra mile to allow an airgapped network with no Internet access.

If the server is Crossplay, all parties would need outbound Internet access and you'd pretty much have no choice in involving a relay server on the public Internet hosted by Microsoft. Any VPN would be ignored unless it was the route to the Internet (i.e. default gateway)

[elfin coral]

so...if i want to have crossplay, could i connect the device to a router that is connected to the internet router?

so the device isn't directly connecting to the internet but has an approved path to the internet

[final current]

Yep, should work. Sounds like a "double NAT" kind of situation. Those extra hops will add latency, which Crossplay is already bad at, but it ought to work.

The one thing to watch out for when using Crossplay like that is that only one Valheim server is using a given "port" on this network. Even though players don't directly connect to the Valheim-advertised port with Crossplay, the combination of external/Internet IP address and advertised port are used as an identity for the relay server Microsoft sets up for you.

To put it another way, if a bunch of PCs access the Internet through the same connection and effectively have the same Internet IP address, Valheim server A advertising port 2456 would compete with Valheim server B advertising port 2456. You'd want to either specify a different -port argument value or use the uncommon -instanceid argument combined with join-code-only connecting.

[elfin coral]

basically, i'm asking because my pi that is hosting my vds-es has a secondary function, that i'd want to take it off of direct internet connection for

and yeah, i suppose i would be creating a double nat...but one in which i have complete control rather than my isp being cheap

[undone pewter]

hey guys i'm hosting my own server for me and my friends but i noticed lately that mobs start to lag

when i stagger an enemy during its attack it doesn't show that they are staggered instantly but rather a 50ms later

is there a way i can fix this? this wasnt like that 20-30 hours of gameplay ago

the server is locally on my PC, my router is gigabit capable and my ping to the rest of the party is ~1ms

ah also i dont run any mods

[outer kiln]

happens to me and my friend too

every now and then mobs lag hard

[final current]

Here's my usual checklist to run through: #dedicated-server message

[undone pewter]

Usually the lag+desync culprit checklist is:
The server is using Crossplay instead of direct connectivity in Steam mode. -~~ Don't know what it is or how to change this~~
The server or one of the players is using Wi-fi instead of Ethernet, fiber, or DAC, especially if they are first to an area - one of the players may have slow internet
One of the players is on sub-par hardware, especially if they are first to an area. - hardware is decent
One of the players is using a VPN - no
One of the players is using an Internet security suite - what is this and no
Someone on the server or a player's network is saturating that connection, e.g. with bittorrent - no
Ashlands biome mobs, they can be laggy in multiplayer, even when other conditions are relatively dealt with - no
The server is using the Iron Gate container builder/launcher, but with the older steamclient.so that ships with dedicated server. - no

so you are telling me that if one of the players in the game has slow internet the whole server lags?

valheim_server -nographics -batchmode -name "Cat server" -port 2456 -world "catwrd" -password "asd" -crossplay
does this mean with crossplay

should i disable it

[final current]

Yep. That's using Crossplay. It's default in the included script templates because it's the easiest to get up and running.

I would consider disabling it if you have some IT networking savvy. It means you will be responsible for making your server's UDP ports accessible to the Internet

[undone pewter]

i already did open my UDP ports for the server

[plain trellis]

The player that first enters a in-world cell, are master of that cell, and responseble of most of the game-calculations in that cell, for all players in the same cell. So that players internet connections, network-hardware/setup and client hardware, are possible reasons for lag for all players in that cell.

[undone pewter]

thanks

do you think its selfish to remove this lmao and people in the server with poor connection will lag more and ill play decently

[final current]

Disabling Crossplay will have the biggest impact for you if I had to guess

[undone pewter]

i thought enabling the port forwarding on your router/pc is a no brainer when hosting a server

no other game has workaround for this

[plain trellis]

Every member of your server should first run this test:
https://www.waveform.com/tools/bufferbloat
That will single out those that need to be removed from the server

[final current]

With Crossplay, your port forwarding is ignored. Microsoft handles the Internet networking for you using a relay.

[undone pewter]

by the way if i run my server on 2456 is it necessary to enable 2456-2458 or 2456 is just fine, because when i did it i didnt read the comment in the script that says it needs those ports specifically

i hope it doesn't create some extra connections out of nowhere

[final current]

You should forward 2456 and 2457 when Crossplay is disabled

[undone pewter]

alright

[final current]

I'm guessing 2458 was thinking ahead to the future. Up to you if you want to include it but I don't think the server listens on it

Heading to sleep. Good luck

[undone pewter]

thanks for the help gn

Edit: Disregard. I see that my docker image needs an update, due to it gets confused by an BepInEx update

[plain trellis]

Yeah... This problem is isolated to servers with BepInEx, and for me the docker image is built on Debian 11, and now needs GLIBC_2.33/34/38 to run the server. Something and some where got updated the past 8 hours, and now the valheim server (with BepInEx) will not run in the container. Another server I run, with the same image, on the same system, are without BepInEx, and runs fine.

On the positive side; My Proxmox got its first restart of 2025...

[steel snow]

i plan to create a dedicated server but have some concerns regarding, what website is best to host it on and how do i make sure console players will be able to join. Moneys not an issue so the amount a package will cost on 1 website opposed to another isnt a consideration i need

[plain trellis]

This channel are for players discussing creating and troubleshooting their own private dedicated server, on their own private hardware. Not random 3rd party hosting sites.

[steel snow]

i asked about website hosting about a month ago and got directed here so assumed asking this wasnt an issue.

[plain trellis]

The more you know. Have no clue what is more important for you; price, support, features, infrastructure, proximity, etc

I would suggest you look for some reviews and customer feedback of hosting companies that google suggests

[steel snow]

ive honestly never hosted a server before on any game really so not familiar with anything. Price isnt an issue idm spending money. I only opted to a 3rd party hosting option as it seems to take care of 90% of things for u.

[plain trellis]

If price isn't a issue; Buy your own hardware, and set up your own server

[steel snow]

my main concern though is with compatability and givings users the best experiance

[steel snow]

ofcourse i mean withthin reason, im not buying a whole other pc to host

and that will not have 90% of things taken care of for me

[plain trellis]

The tutorial in pin comment should get you started

[steel snow]

as i said i opted to a 3rd party option as im not familiar with port fowarding and everything

[plain trellis]

That is the very reason you should google this. Find out what's important for you, and what's not.

[steel snow]

so Gyro the reason im using the "Dedicated server" channel is to get informed about this

[plain trellis]

And we don't have it.

[steel snow]

"you" dont have it

[plain trellis]

Please read the tag in top of this channel

[steel snow]

when u say "we" ur including the entire server and multiple people who do run server via 3rd party websites who could tell me

[steel snow]

we could have just started with saying this

but as i said i was directed to use this channel

[plain trellis]

Sorry

[steel snow]

no reason to be dude. We had a misunderstanding

[final current]

It's no worries. It would be nice to be able to share that kind of advice, but it opens up the doors to spam, scam, shills, veiled ads, and being the official discord can give the mistaken appearance of official endorsement from the developer, publisher, or contractors.

[steel snow]

thats a fair enough reason

[final current]

https://www.reddit.com/r/valheim/ can be one place to search around beyond a regular search engine. It's susceptible to manipulation of course.

[agile pecan]

I don't know if this is relevant or if you have already solved it, but BepInEx on thunderstore was updated in the last 8 hours. Sounds like it could be related

[gilded lintel]

looks good

[final current]

Yes, the libdoorstop build in @stark lynx's mod pack is built against a newer glibc version now, maybe 2.38. That puts it beyond compatibility with Debian stable, breaking most Valheim Dedicated Server images out there that auto-update against that pack.

[final current]

As of today:

• Images built with Iron Gate's script use glibc 2.35
• ich777's image is on glibc 2.36
• lloesche's image is on glibc 2.31
• mbround18's image is on glibc 2.35

[elfin coral]

once you do decide on a site, we could, possibly, help guide you with the actual set up process. we just can't make recommendations on which site to use

[steel snow]

ive managed to do so, bought a server just now and would love some help

ive figured out how to add steam ids to white list people but how do i enable it so people whos ids arent on the permitted list cant join

[knotty oracle]

The whitelist should already do that.

[steel snow]

so i dont have to enable a setting to apply whitelisting

[final current]

Within 10 seconds of updating <savedir>/permittedlist.txt with 1 or more player IDs, the server will block anyone not on that list.

If you don't have access to <savedir>/permittedlist.txt, you might check with the managed features from the hosting provider for supplying and applying the permittedlist.

[steel snow]

ah i see, okay managed that. just having 1 more issue of the connecting

the servers on but when we input the server ip it shows the server ip as the name and also doesnt let us connect

[final current]

Using Crossplay or not, and is it public or not?

[steel snow]

disabled public and crossplay is on

[final current]

With Crossplay on, make sure you're including the platform prefix in the player IDs you add to the permitted list, e.g. Steam_<Steam64ID>

[steel snow]

haha dont worry justin, i fixed it and am too embarrased to say why it didnt owrk

[final current]

hehe no worries 🙂

[steel snow]

although will have a few more questions in #mods-discussion if u can help

[glad prawn]

Hey folks - Today my valheim server (docker image lloesche/valheim-server) did some updates and now it crashes on startup with:

/opt/valheim/bepinex/valheim_server.x86_64: /lib/x86_64-linux-gnu/libc.so.6: version GLIBC_2.34' not found (required by /opt/valheim/bepinex/doorstop_libs/libdoorstop_x64.so)

I confirmed that this was bepinex-related by disabling bepinex and restarting (success). If anyone else uses this image and has an idea how to fix, I'd love to hear it. Thanks 🙂

I also did a fresh pull and bootstrap, once without bepinex, once with. Again, it failed with the same error when bepinex is enabled.

[final current]

#dedicated-server message

#mods-discussion message

[glad prawn]

Hmmm so known issue then

[final current]

Either the images will have to switch to a different BepInEx pack, freeze to a specific pack version, upgrade their base images or the pack author will have to make a new release built against an older system C library.

[glad prawn]

I see. Thanks for confirming.

I couldn't find any references to a lloesche discord server. If anyone knows of one, I'd like to pop over there to follow progress

[final current]

Yeah, if he's on here I don't know his nick. His won't be the only image affected though

I can make some manual hack for folks in a couple hours if it's not resolved by then

[tranquil ibex]

Hi all, I already have a dedicated server that I start with the bat file. However, it's been so long I played that I forgot stuff. How do I start a new world that will be on the dedicated server? I dont want to make a new world and find out it isn't being hosted on the server bec I might have a friend join in later

[final current]

The world name you specify in the -world <world name> argument in the launch command determines what files will be looked for. If no world exists with that name, it will be created (and used).

@plain trellis and @glad prawn, and anyone else encountering it, if you can't switch to Vanilla for the time being, the quickest workaround I could come up with, specific to lloesche's image:

-e PRE_UPDATE_CHECK_HOOK="sed -i -e s,Valheim/\",Valheim/5.4.2202/\", -e s,\.latest\.download_url,\.download_url, /usr/local/bin/bepinex-updater"

[tranquil ibex]

AH okay, so I can just start a new world in the game, name it "XYZ" and then close game, edit the bat file and replace the old world name with "XYZ" did I get that right?

[final current]

I wouldn't recommend running the game on the same PC as the server without some careful planning, but yes, that would work.

Even easier, if you aren't applying custom presets, modifiers, or global keys, you can just do -world XYZ in the launch arguments and the server will create it for you in <savedir>\worlds_local once it doesn't find it. Just give it a few minutes to generate and don't worry about the "No instance when setting progress" messages.

If you insist on running the game on the same PC, I would make sure to move the world to local management from the in-game UI after you create it but before you start the server. That way, you'll avoid the game's cloud syncing competing with the server's local-only management.

[tranquil ibex]

Understood, so I just created this world but haven't started it. How do I ensure its on local management?

The mew world is horizon

Is it already on local since the warning on the right says I'm not on cloud?

[final current]

You got it. The 💾 means it's locally managed.

[tranquil ibex]

Tyty

[tranquil ibex]

Okay, something weird. I'm in the new world. Got dropped by the crow. However i can see that the bossess I defeated from the old world have carried over. Very weird. Do I need to change something else in the bat file?

[final current]

You specified a world name via -world <world name> that you had not used before?

You can paste us the whole line from the .bat file, feel free to obfuscate the password.

[tranquil ibex]

I edited the .bat file and changed the name there to the new world name. Is there another file I need to edit? Okay, here's the bat file ss

[final current]

So Dedicated is the new name or the old name?

[tranquil ibex]

ahhh

Should both be horizon?

Last time, it was Midgard after the batchname and then the area after world was dedicated

[final current]

The server name specified in -name is just decorative. Affects what the other party sees in the server list if they receive your metadata successfully. Can be whatever you want.

[tranquil ibex]

ah okay, ill edit it and see now

Yes, this works now. Thanks a ton mang

[plain trellis]

Thanks! When I tested it (in a rush) i got this:
`Aug 6 07:00:12 supervisord: valheim-updater INFO - Running pre update check hook: "sed -i s,Valheim/",Valheim/5.4.2202/", /usr/local/bin/bepinex-updater"

Aug 6 07:00:12 supervisord: valheim-updater /usr/local/bin/valheim-updater: line 279: sed -i s,Valheim/",Valheim/5.4.2202/", /usr/local/bin/bepinex-updater: No such file or directory`
and the server still wouldn't start. I didn't have time to look more in to it right now.

[final current]

Looks like the double-quotation marks got included verbatim. I'm guessing you aren't using a docker run or podman run command on a shell?

If that's the case, e.g. this is a UI form for entering env vars, you'd want to drop the outer quotation marks. You might also have to remove the backslashes leading the inner quotation marks.

[sage nexus]

idk the actual context, but your syntax looks off

x='Valheim/"'; echo $x; echo $(sed 's|Valheim\/"|Valheim\/5.4.2202\/"|'<<<$x)
Valheim/"
Valheim/5.4.2202/"

[final current]

Certainly possible. What did I miss?

[sage nexus]

enclosing with ticks i guess is one thing sed 's|||'

but i was really looking at gyros paste

[final current]

I just used commas instead of pipes for safety. Should hopefully have the same effect

[sage nexus]

Yeah sory for interrupting, it just looked weird so i had to tinker while i wait for my rice cooker to ding

x='blahBlahBlah/Valheim/guffGuff"'; echo $x; echo $(sed -E 's|^(.*Valheim\/)(.*")$|\15.4.2202\/\2|'<<<$x)
blahBlahBlah/Valheim/guffGuff"
blahBlahBlah/Valheim/5.4.2202/guffGuff"

[plain trellis]

I'm sorry, but can't provide info right now. Much IRL going on. But I use docker compose file, and just did a quick test removing the outer " and came further. But now the setup can't unpack the bepinex.zip

ok well to me this
Running pre update check hook: "sed -i s,Valheim/\",Valheim/5.4.2202/\", /usr/local/bin/bepinex-updater"
should read :

[plain trellis]

got to go, sorry

[final current]

Thanks for sharing the result. I can probably figure out a compose-compatible YAML for it tomorrow if no one else gets around to it.

Bed time for me

[glad prawn]

Have any of the docker image maintainers addressed this yet?

[final current]

The pack authors released a new version to bring down the glibc requirement. There are still changes that image authors will need to incorporate if they use BepInEx for metrics or mods. In the meantime, did you try the env variable hook workaround, @glad prawn?

[floral jay]

a file was named wrong in the newest upload but eaily worked around. I also found a way to build doorstop for even lower requirements and submitted it upstream. but honestly it feels like nobody else is using current bepinex 5 on linux outside of valheim or these issues should have been spotted sooner.

[glad prawn]

Ah I see, version 5.4.2331 of the bepinex pack on thunderstore. Funnily enough they specifically called out lloesche's image to say that it was too old to work 😉

[final current]

Yes, the env variable hook will lock it to the prior pack release in the meantime.

[floral jay]

yes, the libdoorstopx64.so in that pack which should be called libdoorstop_x64.so was compiled on ubuntu2204 bringing down the requirement but debian 11 is still really old

but only 3 more days until debian 13 is released!

[final current]

Popular image glibc versions: #dedicated-server message

[glad prawn]

Sure, but that doesn't help the people who built their ecosystem on top of lloesche's image. Maybe it's time to switch?

[floral jay]

if lloesche switches from debian 11 to debian 12 as the base image it will work again

debian 11 will be oldoldstable in 3 days. the container really needs updated

[glad prawn]

Agreed for sure

[final current]

This was the first update of this pack in a couple years and it was done in the middle of the week when many Dedicated Server image authors are working their day job. I'm betting lloesche will be able to get around to it this weekend if he's available.

In the meantime, let me know if you need help with the hook.

[floral jay]

its unfortunete that servers broke but this does point out that auto updating mods on a server isnt the best practice

[glad prawn]

Will do. And, sorry, I'm not ignoring the fact that you've given us a workaround 🙂 I'm just trying to gather info

[final current]

Agreed, and many server operators have BepInEx enabled even without using mods.

[floral jay]

also worth noting that even if libdoorstop didnt require a newer glibc, they still would have all broken from doorstops new envvars

somebody said gportal support is blaming the mod for being broken but I dont have an account to see their forums to know more

[rancid sand]

Is mbround18's image the the recommended situation now for a modded container?

[floral jay]

afaik none work with bepinex newer than 5.4.2202 at this point

[glad prawn]

According to Justin's list ( #dedicated-server message ) at least three should with today's BepInEx change on the Thunderstore... right?

lloesche is the only one that's still too old for the GLIBC 2.34 rebuild

[floral jay]

the environment vars used by libdoorstop also changed

[glad prawn]

Ah right I see that now

[rancid sand]

Thanks for this update. Im just getting into the details since it's not working. I did a test run of mbround18 and the server launches. I mean even lloesche works to connect to now but mads don't download, nor are the being read. I will look into rolling back.

[plain trellis]

Thank you for your effort to help server owners with this un-predicted consequences of updating BepInEx.
Yes, I use lloesche docker image, and added your suggestion under the enviroment part of the YAML file. Also now tried to remove the \ before the inner ". Still no dice for me, the server can't find/unzip the BepInEx.zip file it downloaded, and goes in loop on the
valheim-updater ERROR - Failed to extract and install BepInEx - retrying later
I see on github that others got use of your suggestion, so something is off in my end.

[final current]

DM me your composition YAML if you're up for it and I'll see if I can get it running locally.

[plain trellis]

Thank you. DM on the way

[elfin stratus]

So if people kept their linux os up to date there were no issues? 🫢

[final current]

Kinda. They would have to be on one of the bleeding-edge distros like Arch, Gentoo, or near-bleeding-edge like Ubuntu. And image authors don't necessarily expect to have to swap out their base image often for something like a game server.

Outside of the system C library change, there was also a breaking change in environment variable setup that would potentially require manual effort depending on how they launch Valheim.

Though as Arrowmaster suggested, another approach would have been not auto-updating the BepInEx pack, which is where most of the reported issues are stemming from.

[glad prawn]

New bepinex on Thunderstore to fix the file name issue

[elfin stratus]

I will for sure turn this off in gportal console 😅

[elfin stratus]

Welp, you can’t turn off autoupdate in gportal dashboard

🤷‍♂️

[final current]

Are they running one of the containers our community has made? Wouldn't surprise me.

[elfin stratus]

No idea but since they still havent fixed it themselves I assume yes 😅

[floral jay]

have they admitted it is a problem on their side yet? somebody said their support responded that it was a "bad mod release" or something like that when the first bepinex update came hit and broke autoupdating servers

[glad prawn]

I think we can all agree that blind automatic updates with no failback plan (backups) is universally unadvisable. Personally, I'd be perfectly fine with notifications instead. If the image isn't going to take backups before overwriting with a different version of something, at least give me the chance to do it.

[frozen zephyr]

Don't use a docker container someone else made and you don't have to worry about that

[mint gorge]

As of right now, G-Portal is still claiming to be working on the issue. This was the response to my ticket:
"unfortunately they stopped working generally, our devs are already checking this. There is no workaround so far as everything seems to be in place.
We are working on getting BepinEx working correctly as soon as possible."

Is there anything we can do from the server-admin side of things? Or is it out of our control and are we to wait until G-Portal fixes it on their end?

Also, maybe anyone knows, what does this mean for ServerCharacters? It stopped saving player profiles as of 01:48 this morning for me.
(A workaround would maybe be to enable Backup Only Mode and let that run for a day, before turning it back on again)

[mint gorge]

Little update on my issue. Manually rolling back to Valheim BepInEx 5.4.2202 works like a charm.
Regarding ServerCharacters, you can run this in backup-only mode until all players have logged in again once, then turn the backup-only mode off to regain its functionality.

[gilded vine]

What happens to a player who doesn't log in before you turn it back on? He/she can't log on to the server? Or they log in to an older character save?

[floral jay]

so gportal isnt autoupdating anymore?

[mint gorge]

I did some testing.
When the mod is in backup-only mode, it loads their client side save. Even if you restore the old server-side saves. (which you should)
Our issues started at 2am last night, so I noted down who has logged in since then. I will wait until they all have come online (and their backups have updated) and then disable backup-only mode, to regain functionality.

Edit because I misunderstood your question: I am going to assume that if they log in only after you enabled it, they will either be forced to the last server-side update or flatout be told to make a new character. I havent tested this yet because.. I dont want to mess with it again now its working :P
From what I can gather, worst-case is they send you their client-side save and you can just throw that in there
