Venice Unleashed

I have setup servers before and with no issues in the past. However, I am now getting these errors where players join the server and they get kicked off after 1-4 seconds. I tried to join several times but can randomly be kicked out after 1-4 seconds. looking at the log there are a few entries which looks like server connection is timing out. Firewall correctly configure with ports open, gametracker can track etc. Still, must be something I am missing! Anybody else with similar errors?

Antivirus maybe.
Try disbaling AV and firewall for testing.
