Current behavior

I created the server using the recommended docker-compose.yml and default.env files (only modified the password). Then I logged into the container using docker exec -ti palworld-dedicated-server bash. When I use the command "rcon showplayers", it produces the following error:

cli: execute: auth: rcon: authentication failed

my docker-compose.yml is:

version: '3.9'
services:
  palworld-dedicated-server:
    #build: .
    container_name: palworld-dedicated-server
    image: jammsen/palworld-dedicated-server:latest
    restart: unless-stopped
    ports:
      - target: 8211 # Gamerserver port inside of the container
        published: 8211 # Gamerserver port on your host
        protocol: udp
        mode: host
      - target: 25575 # RCON port inside of the container
        published: 25575 # RCON port on your host
        protocol: tcp
        mode: host
    env_file:
      - ./default.env
    volumes:
      - /home/zzz/pal-data:/palworld

my default.env is:

That seems strange to me.

Can you run "docker exec -ti palworld-dedicated-server cat /palworld/Pal/Saved/Config/LinuxServer/PalWorldSettings.ini" command to see if it takes your default.env file.

And is your server working? Do you have folders in /home/zzz/pal-data?

Could you share your docker logs too? Redact the password and public IP if there ofc

docker logs -t palworld-dedicated-server

Also see if the file rcon.yaml is correctly setup

docker exec palworld-dedicated-server cat rcon.yaml

Hey @zwh8800 - Both of the are right. Please follow their advice and provide additional data to help us help you.

Hello! I ran into this issue yesterday. I encountered the issue by doing the following: 1) Deploy a default server with the example YAML provided on the README 2) Updated the SERVER_DESCRIPTION value in the YAML configuration file with a \n character 3) docker-compose up --force-recreate 4) docker-compose down 5) docker-compose up

Now you should have authentication errors due to a malformed PalWorldSettings.ini. The workaround I did was to bring the container down and restore the ini file with one from a previous backup

I get the same error It happens when migrate server (I used to host my server on gamever, and now I wont to host it locally)

It solved when deleting worldOption.sav file in Pal/Saved/SaveGames/0/XXXXX Full path would be Pal/Saved/SaveGames/0/XXXXX/worldOption.sav

It seems like changing rcon password is not updating on worldOption.sav (maybe rcon settings configured inside this file)
