I have tried the following: Restarting computer and arma
create my own server (Whcih worked but I can't join other servers)
Allowing arma 3 to go thru the firewall both in public and "home networks"
Router firewall is turned off.
I also have UAC completley turned off.
The first time I tried to join a multiplayer server, I got to the character selection screen, but the server wasn't playing yet and I couldn't press the OK button. After about 2 minutes, I disconnected from the server. The next time I tried to join a server, this happned and I have not been able to join servers since then.
