docker logs

the logs are parts of docker compose logs

when the container is launching. I think this part is related.

@piutranq Huginn runs essentially a rcon get status command, is your valheim server offline?

[piutranq]

Thanks for advice, the problem is fixed for now

This is not problem of huginn.
But my server is private (PUBLIC=0) so the server can't queried by odin status. (it is not error, notified in odin --help)
so I have changed docker-compose.yaml to PUBLIC=1 and the problem is fixed.

But, can I query server status when the server is private?
I want to hide my server from public server list.

[mbround18]

@piutranq not really, the server status comes from the server query list which has to be online to do so

[cameronwp]

Glad I found this! The same issue tripped me up. @mbround18 do you take PRs? I'd love to submit one that mentions needing PUBLIC=1 in the Huginn docs.

[mbround18]

@cameronwp yes! Feel free to toss one up! :)

[cameronwp]

Great! Submitted #643

Appreciate the hard work on this. Great job making it easy to run a Valheim server.
