Dedicated server problem

[Ataros]

Lobby was created for those who does not have external IP, i.e. put by provider behind a router. I had to purchase external IP from provider to be able to start server in Server room.

If it is not the issue, then try deleting old firewall rules for both Steam and Launcher and create new rules which are absolutely empty (open) for both applications and both ways of traffic. You can limit unnecessary ports later when it works.

Try letting Steam know that server exists:

- open Steam - Servers - LAN. Do you see server here?
- add server to Steam Favorites by IP
- ask someone else add server to Steam Favorites IP
- ask someone to direct connect to server with IP or from Favorites
