Invisible servers

Currently my xonotic doesn't list the servers on main menu,can't connect to one even if type it's id on the console :/
Dunno what is happening here, I think though that my ports are blocked wich prevents the game from seeing the servers...
Can I fix this somehow? -.-

You don't need inbound port forwarding to play, and outbound communication usually isn't subjected to port blocking.

Do you have a firewall? Were you previously able to browse the servers and connect with the same link? What changed, and when?

Right now I am living at an apartment far away from my natal city, with it's wifi support I can't even download torrents , (blocked ports)
I speculate my firewall isn't a issue ,cause at home I could connect without any sort of problem, still , no dice if I disable it :/

If they block torrents, they might be blocking other ports... Ask your network administrator.

Is this even legal in a domestic network?

For torrents seems reasonable to bee blocked, otherwise the whole network will cripple, anyways I shall talk to the network administrator regarding my ports.

Port whitelisting aren't unheard of (in public networks at least). It could be allowing only http(s), ftp, ssh and so on.
