mverse seemingly fails to start a server. both internet and LAN mode seemingly never enable port for listening. attaching Player.log (mverse server has started according to game, but netstat -tulpn | grep LISTEN shows no ports listened to by the game

📎 E9rSGbZ.log

#

line 139 should be when mverse started

#

port state for listening, launching/closing mverse and launching/closing the game changes nothing

#

among other notable moments:
hosting & connecting via lan doesn't work (even as i brought laptop with me to check)
hosting & connecting doesn't work on windows
a year or more ago i did play on this computer in mverse with same person on windows
the router didn't change since

Epic Manager: Category - LogEOSConnect Message - DeviceId access credentials already exist for the current user profile on the local device.
this part is what prevents the game from starting a lobby properly, but i am not sure what the steps are to fix it other than "try again later"

#

one thing is that the game doesn't handle switching between LAN and Internet properly in the same session, so if you want to try one or the other you should restart the game

#

the error you got indicates you might be using the Internet option with two instances of the game on the same network which doesnt work and you need to use LAN, but restart the game first if you used Internet option before

#

Yeah, the EOS stuff isn't (as it existed at the time CW4 was created and how it was implemented in the game) fault tolerant and requires a game restart if you switch most anything (or anything fails)

thorn wyvern Feb 15, 2026, 6:51 AM

#

i am pretty sure it was right after the game was restarted (for logs clarity), but here's another piece of puzzle: log of starting mverse after full computer restart, booting up the game first time

📎 Player.log

tepid sparrow Feb 15, 2026, 6:52 AM

#

and you are not also running mverse/trying to join on another computer in the same network?

thorn wyvern Feb 15, 2026, 6:52 AM

#

no. running in internet mode, no other computer working in LAN

#

i can restart pc and try LAN if that would clarify logs

tepid sparrow Feb 15, 2026, 6:54 AM

#

do you have EGS running on the computer in the background?

thorn wyvern Feb 15, 2026, 6:55 AM

#

Epic Games Service i assume? i don't have EGS on my pc, but can't tell if any other process uses it, though it's unlikely (running rn from user side: file explorer, notepad, CW4, discord, steam, wireguard)

tepid sparrow Feb 15, 2026, 6:56 AM

#

the store

thorn wyvern Feb 15, 2026, 6:56 AM

#

don't have it

tepid sparrow Feb 15, 2026, 6:58 AM

#

as unfortunate as it is, my only remaining idea is that maybe EOS is having trouble identifying the local computer when it is running through proton... i am on linux myself right now actually so i'll go and check out of curiosity if i get the same problem

#

Epic is not known for their linux support (or lack thereof)

thorn wyvern Feb 15, 2026, 6:59 AM

#

i did think it may be linux issue, but then it would have worked on windows (which it didn't)

tepid sparrow Feb 15, 2026, 7:00 AM

#

ah right, you did mention that

thorn wyvern Feb 15, 2026, 7:01 AM

#

though it is possible it happened for an entirely other reason (such as accidental relaunching of mverse)

tepid sparrow Feb 15, 2026, 7:01 AM

#

it seems like my game hosted a lobby without an issue, at least looking at the log

#

want to try joining to see if at least that works?

thorn wyvern Feb 15, 2026, 7:01 AM

#

sure

*relaunching game for clarity*

tepid sparrow Feb 15, 2026, 7:02 AM

#

naturally

#

which proton version do you use?

#

well eh, if it doesnt work on windows too perhaps that does not matter

thorn wyvern Feb 15, 2026, 7:04 AM

#

connection failure

📎 Player.log

tepid sparrow Feb 15, 2026, 7:05 AM

#

yeah, you keep getting the same error about access credentials already existing on the local machine.. as if something was running and initializing EOS already so CW4 can't do it. but you don't have anything like that running

thorn wyvern Feb 15, 2026, 7:06 AM

#

tepid sparrow which proton version do you use?

unspecified. i checked mark and it briedly showed proton 9.0-4 before moving to hotfix

#

oh hey, restarting game at proton experimental and hosting via lan doesn't have that issue

📎 Player.log

tepid sparrow Feb 15, 2026, 7:07 AM

#

it won't, LAN does not use EOS at all

thorn wyvern Feb 15, 2026, 7:09 AM

#

on internet hosting same error

thorn wyvern Feb 15, 2026, 7:09 AM

#

tepid sparrow it won't, LAN does not use EOS at all

huh. i recall we tried to LAN and we failed too. that's odd

#

i guess we try again

tepid sparrow Feb 15, 2026, 7:10 AM

#

you might not have restarted the game after trying Internet

#

then LAN is likely not to work

thorn wyvern Feb 15, 2026, 7:10 AM

#

possible yeah

#

also, is EGS library outdated for CW4? because i can't see the trace it points at

tepid sparrow Feb 15, 2026, 7:11 AM

#

i have no idea, depends on the definition of outdated, the mverse update was in 2021, i doubt it was updated much since then

#

did you make two attempts to connect to my lobby?

thorn wyvern Feb 15, 2026, 7:13 AM

#

negative

tepid sparrow Feb 15, 2026, 7:13 AM

#

i found two connection failures in my log

#

maybe it just crashed twice for some reason

#

but you did connect to me it seems like

#

it just failed

thorn wyvern Feb 15, 2026, 7:14 AM

#

tbf "does everything mverse related twice" is a plausible reason why game acts like i already have mverse hosted when i host

that it definitely would

thorn wyvern Feb 15, 2026, 7:15 AM

#

i guess i could have uncarefully clicked again, care to check it another time?

tepid sparrow Feb 15, 2026, 7:16 AM

#

sure

#

hm

#

now that i have started the game back up again

thorn wyvern Feb 15, 2026, 7:17 AM

you mean it may be persistent between relaunches?

tepid sparrow Feb 15, 2026, 7:18 AM

#

i don't know, all i know is that i did not have the error the first time i launched, but now it appeared after restarting the game and hosting again

feel free to try but i doubt it will connect given the circumstances

fail

tepid sparrow Feb 15, 2026, 7:19 AM

#

my game did log a failure as well, a single failure this time

#

wait

#

and then a few seconds later it logged a second failure

thorn wyvern Feb 15, 2026, 7:20 AM

#

🚬

#

let me restart pc, see if it changes anything

tepid sparrow Feb 15, 2026, 7:20 AM

#

well it could also be that someone is reading this thread and also trying to join 😄

#

its not completely unlikely

#

should probably be DMing you these invites

thorn wyvern Feb 15, 2026, 7:22 AM

#

nah, you overestimate my number of currently awake friends who want to play mverse (0, may become 1 in 4 hours)

tepid sparrow Feb 15, 2026, 7:23 AM

#

well anyone can read this thread

thorn wyvern Feb 15, 2026, 7:26 AM

#

nah not at all

📎 Player.log

#

same thing every time

tepid sparrow Feb 15, 2026, 7:28 AM

#

if you have a way of LAN connecting with your friends, that might be the best thing to try. my best guess is that it's ultimately some linux problem that ended up also breaking the windows version on the same local machine, perhaps its not cleaning up correctly on game exit or something

thorn wyvern Feb 15, 2026, 7:28 AM

#

lack of isolation is unlikely, since the appdata folder is different and even game for linux is another copy on linux disk

#

but i'll try LAN and report results, thank you!

tepid sparrow Feb 15, 2026, 7:30 AM

#

mverse is still "experimental" and always will be, and the LAN option at least should be fairly bulletproof. there is a way to test it yourself too, you can run more than one instance of the game locally to test it

#

this wiki page explains how, although the instructions are for windows, you can probably figure it out
