Failed to Connect...change firewall settings

[Atavism]

Hi Support

I can access and join a game on Red Alert but when the game starts with the MVC, it keeps doing this 25 second countdown and then another message appears and it says

"Failed to Connect..Check Firewall, Anti-virus settings, Wifi "

It was working fine for four sessions before this started happening.

Now I have changed my firewall settings to allow the ccnet, raspawn, any other ideas about how to solve this issue ??
