Problem Description

Issue

Everything to my knowledge looks setup but I am fairly new to steam server setups. I started, updated, and attempted to join. And ports were also forwarded as well. First with the ports AMP lists then with both TCP/UDP and problem stayed the same with the listing not being visible in game and being unjoinable via AMP link

Reproduction Steps

  • Created instance, updated, shows started successfully
  • After creating the server and starting it (not messing with any password settings) click on the connection link provided by AMP
  • After failing to join via connection link, logged into the game and checked the server list in game. Its not visible via LAN or regular server list
