"not able"

yesterday i install Co Un for gaming on-line with a friend.
After the installation is complete, my friend tell me that near my avatar in Comodo Unite i have the notice “not able”.
However the connection don’t start.

Can you help me?

I’ve a router, i think it’s not a firewall’s problem, beacose i’ve deactivate all of them…


  Would you please provide your OS and firewall settings so we could check it? Thanks.
