Player logging is attempting running rcon before the server finishes booting and rcon is started yet.

Not a big deal but should still be fixed.

Player logging is attempting running rcon before the server finishes booting and rcon is started yet.

Not a big deal but should still be fixed.

There is no user currently trying to log in. It showed up just after starting the instance.
Is there anything can do to confirm the rcon is working properly?

[Dashboy1998]

You can run rcon to verify it's running correctly docker exec palworld-server rcon-cli info

[Dashboy1998]

To clarify player logging runs on a timer. While it would be great to trigger based on a new player joining/leaving I don't know of a way for us to implement that.

Thanks @Dashboy1998, just wondering the benefit of running rcon? Is it related to server management? Considering only two local users probably not worth to activate the rcon?

[Dashboy1998]

Rcon is the only way to manage the server unless you do only in game commands.

Rcon is the only way for the container to trigger a save or properly shutdown.

Without rcon there's no way for the container to save so your backups might not actually be useful as player data and world data save out of sync.

[DHS1001]

Thanks for the quick fixed :)

This issue is still happening in my instance. I just pulled as of half an hour ago. Connecting to rcon via docker-compose exec -it palworld-server rcon-cli fails with cli: execute: auth: rcon: dial tcp 127.0.0.1:25575: connect: connection refused

Waiting for RCON port to open to show player logging... gets spammed repeatedly in the logs.
