Problem Description

Issue

After opening Sons on Windows 11 PC, clicked on Multiplayer, Join, Direct and entered the Endpoint info.

Reproduction Steps

  • Verified the instance is running. It is.
  • Verified the ports are available through the firewall
  • Tested connectivity from Windows 11 on local network. Ping works as well as test-netconnection with port 2224.
  • Used PortQueryUI to test UDP ports and the test was inconclusive.
  • Ran updates and rebooted server.

Are client and server on the same machine?

Did you try direct connect with the local IP and game port?

3

No server is an Ubuntu Desktop server and client is a Windows box on the same network. Yes, I tried the direct connect.

I haven’t messed around with SOTF myself, but this may be one of those servers that need to be port forwarded even for local clients. Also likely need NAT hairpin/loopback enabled
