The black road

It's better if you create your own game and wait for players as most people will use forums when they have an issue with the server itself.

 

Portforward the appropiate ports if you use a router and wish others to join your game otherwise check your firewall settings.

 

If ports are still closed then your portforward could be incorrect or your internet provider is blocking specific range of ports, although I doubt. What operating system and router model are you using?
