Every time I click "Connect" it times out after several minutes saying "Connection to Server timed out".

Is there a fix?

Double-check your network connections and see if there's a firewall or something blocking VO.

I'm having a similiar problem, I connect and play for 5-10 minutes and then get the connection to server timed out error. I have a decent internet and a great computer. VO is forwarded on my router and firewall... it's quite frustrating, it's just enough time to start and fail a mission.
