Gametracker wont add a TS3 server

[-.-Maverick-.-]

So one of my clanmates is running a TS 3 server on his PC. The server is working perfectly but when I try to add it to the gametracker I get the red screen basicly saying that an error accured.



Any ideas?

Aside from all that is suggested in the screenshot...?

Double check you have entered the IP (if using DynDNS URI you might have to wait abit untill the current IP was propagated) and Port correctly.

edit: sry, checking port was already mentioned.
