Server up to date, client up to date, unable to join server.

[pseudo sleet]

I run a server on my pc and it has worked flawlessly. However I cannot access it in multiplayer after the 1.22.4 update despite the server claiming to be version 1.22.4 and the client having been updated to 1.22.4. Is there anything here that I am missing in this? What should I be troubleshooting?

[long raptor]

Check the server-main.log, what errors does it report when you try to join?

[pseudo sleet]

It says invalid packet received

Supposedly either it failed because the connected party did not properly respond after a period of time, or the established connection failed because the connected host failed to respond.

Mind you the server is running on the same computer.

[long raptor]

Weird, and both are 1.22.4? Are there any mods? If no mods you might want to try just reinstalling

[pseudo sleet]

I initially tried with mods, then without mods. Both dont seem to work.

Going to make a package of the world and the mods I used. Then clean slate my whole install

[pseudo sleet]

It did not work

Port Forwarding is untouched, unlikely to be the issue as it was fine before.

Checked it myself, its fine.

[long raptor]

Does the Invalid Packet Received error also occur if you start a fresh vanilla world with 0 mods?

[pseudo sleet]

Yes

Wait let me think

I think so

Yea

[long raptor]

And if you install 1.22.3 instead, it works fine?

[pseudo sleet]

I did not test 1.22.3 unmodded. Perhaps that is what I will do tomorrow morning

Ill get back to you

[pseudo sleet]

I will test it in a couple hours

[pseudo sleet]

It is not working, even in vanilla.

I don't understand the issue.

It works if I use localhost instead of its ip

This is a development I believe

[pseudo sleet]

Any ideas?

It does say "connected to server, downloading data" yet it downloads a little bit of data like 2kb, then kicks me off.

[long raptor]

If localhost works can you just use that? Or are there other users that that would not work for?

[pseudo sleet]

There are other users outside of my wifi network, so no it would not work for those outside my network.

[pseudo sleet]

Making a new world to see if its a world corruption just in case. I've been trying this with dummy worlds already but I will be using 1.22.3 as a base for now.

localhost test: ✅
public ip test: ❎

I found an IP that works, but I'm not sure if its the localhost IP, so I will get a tester to help me

[pseudo sleet]

Its operable at 1.22.3 but I think it should be at 1.22.5 eventually

[pseudo sleet]

Im going to put the server on a new machine which will be up to date

Wish me luck after 7

Master server response: bad
Could not register to master server, master server says: port not opened.
Ive already port forwarded this thing a while ago, and I double checked after I migrated the server from one piece of hardware to another.

There has to be an issue somewhere between being port forwarded and actually connecting to the server list. I checked my firewall and it seems fine.

[tepid marsh]

did you double check that the port forward is pointing to the correct internal IP address? If its new hardware it will likely have a different IP and therefore your port forward will need updating

[pseudo sleet]

Ahhh ill take a look, idk how I could find that but I'll check

[tepid marsh]

It'll be in your router where the port forward is. Port forwardings typically have fields like:

Inbound port
Outbound port
IP address
TCP / UDP / Both

Etc.
