@CubeCoders-Bot could you help this user with their connectivity issue? See if they’re hosting at home and if so check that they can connect locally to determine if it is a local firewall (on the host itself) or a port forwarding issue.

Alright, let’s troubleshoot this Valheim server issue together.

First things first—are you hosting this server at home? If so, can you check to see if you can connect to the Valheim server locally on your network? This will help us figure out if it’s a problem with your local firewall or the port forwarding. Let me know!
