Problem Description

Issue

He loses connection randomly and cant rejoin immediately without having to kick his character from the server first. He has tried using Hamachi and the servers ip to join. I never lose connection as I’m inside the local network but not on the same computer the server is being run on.

Reproduction Steps

  • port forwarded to allow external ips to connect
  • Started the server as normal
  • lose connection randomly while playing
