[2018] Connection Timeout

I haven't been able to play this because I get the "Connection Timeout" error every time I try to join a lobby. If I press quickplay, nothing happens either. I just get an endless loop of "Starting search", "Found game", "Connecting to session"... Anyone have any idea what this could be? Thanks in advance for any help you guys can provide.

Try enabling upnp in your router if it's not already enabled, also add the game to any firewall exception list you might have, be it hardware or software firewalls
