Valheim server only starts in debug mode

[TheNieman]

The server only starts in debug mode and seems works fine therein. But when I try to run ./vhserver start I get this:

[....] Starting vhserver: VHServerno server running on /tmp/tmux-1003/default
[FAIL] Starting vhserver: Unable to start VHServer

I'm running Ubuntu 20.04.2 on a ACEPC mini PC that's a couple years old.

I googled a bit and thought it might be an issue with tmux, but I'm able to start and exit a tmux session without issue.

There have been a number of these issues in the past but I am unsure what causes it. However, the vast majority of servers don't have this issue. So it is something specific to your distro or install of LinuxGSM. Could you provide the output of ./vhserver post-details. It might provide more info that could be useful

I've got the same issue. My mcservers were working but stopped after updating a script. They were on v20.4.1

Is there anything else you need from me @dgibbs64? I'd really like to be able to run my servers properly again.

[buer22]

It's because you have an apostrophe in the game server name I think. Valheim doesn't like it when you use special characters in the server name. I believe an update is in the pipeline to address this.

Oups well I've got to change that password now lol.

That doesn't explain my mcserver that's now failing with the same error or how both servers run fine in debug mode. Sorry I left both those bits out,I think I forgot because I'd brought it up in Discord.

Thanks a ton @buer22 - that actually sorted it for me!

[nickmayer]

Same thing is happening to me. No special characters anywhere. Discord suggested it may be tmux related so I tried 3 different version (2.8, 3.0b, 3.2) without any changes to outcome.

[nickmayer]

Looks like it is an issue with the call to tmux in command_start.sh. Something is not-quite-right with the quoting. If I remove all double quotes from the line it works fine.

It was attempting to run tmux new-session -d -x "80" -y "23" -s "vhserver" " ./valheim_server.x86_64 -name 'LastAcorn' -password nutzz -port 2456 -world vhserver -public 0". I suspect tmux was trying to treat the command as single filename with spaces include rather than a command with arguments. For example tmux new-session -s test "sleep 5" fails locally because there is no executable named "sleep 5". Whereas tmux new-session -s test sleep 5 works as expected.

[marcleblanc2]

I was stumped on this one for a few hours. This is what worked for me, in the end, I removed the double quotes from the command on command_start.sh#L75

tmux new-session -d -x ${sessionwidth} -y ${sessionheight} -s ${sessionname} ${preexecutable} ${executable} ${startparameters} 2> "${lgsmlogdir}/.${selfname}-tmux-error.tmp"

Borrowed the idea from @nickmayer above.

Running Valheim, on
Ubuntu, 20.04 LTS, amd64 focal image build on 2021-03-15
ldd (Ubuntu GLIBC 2.31-0ubuntu9.2) 2.31
tmux 3.0a
LinuxGSM - Valheim - Version v21.2.2

[Pitabred]

This got me going, too! FYI, the only thing you really need to remove the quotes from is the section after "-s", the others can (and probably should) stay quoted
