Alright then, let’s stick with what AMP gives us. Since you’ve already run ampinstmgr ports and confirmed that the instance is running and listening on UDP/2456 and UDP/2457, let’s move to the next step.

Just to be thorough, let’s confirm a couple more things:

  1. AMP Port Configuration: Make sure AMP’s configuration for your Valheim instance is set to use the ports 2456 and 2457.
  2. Docker Container Network Settings: Even if AMP is managing the ports, ensure that the Docker container’s network is set to host mode. This removes any port mapping confusion.

For AMP configuration, use the web interface:

  • Go to your Valheim instance in AMP.
  • Check the settings to confirm the ports.

To ensure Docker is in host mode, your Docker run command should include --network host. Alternatively, check the container’s network settings via:

docker inspect your_container_name

Look for the "NetworkMode": "host" in the output.

Check these settings and get back to me with what you find! :ship::dashing_away:
