Unable to connect to server.

[sawburst]

This only happens in one server so far, before anyone mentions:

1) Yes, use_secure_connection is set to 0.
2) Yes, Warband is allowed on Firewall.
3) Yes, I have tried with Firewall off.
4) Yes, I'm running as an administrator.
5) Yes, I verified local game integrity or whatever.
6) Yes, I reinstalled the game.

NONE of the solutions above work, so please don't say them again here. Thanks in advance.
