I get disconnected after two rounds?

[RelientTU]

I've been on six servers so far, which isn't an easy task in itself, and I'm being disconnected from each one after two rounds. The "connection problem" timer comes up, but it happens at the same time on each server and I have no connection issues otherwise.

Anyone else having the same problem or know how to fix it?

I haven't made a full round yet.

I'm still having that problem, but I gave up. If anyone knows a fix, I'd appreciate it.
