Unable to connect to specific IP/port

[Ravens_Brunch]

So theres a game server we're trying to connect to but it keeps timing out.

We have 3 different pc's all connected to the 3 broadband router that wont connect. We can all connect to different game servers (obviously with different IP's and ports) running the same game. If we swap to using a smartphone on the Tesco mobile network it works just fine on all 3 pc's. Restarting the router after leaving it offline for several minutes had no affect. The only thing it can be is the router/network. A fix for this would be massively appreciated.
