unable to establish a connection with the gameserver

[devmck]

New CS2 Update has made being able to join friends in a 1v1 impossible, idk if this is a glitch, part of the new update or me, but ever since CS2 Started I've been getting this error trying to join my friends in private games. Screen usually goes black for a second then it says the error "unable to establish a connection with the gameserver", someone please fix. I've looked at firewall, internet, restarted client and game as well as verifying game files please help!

I had the same problem when trying to play 1vs1 - "unable to establish a connection with the game server". I was able to solve it by adding Port Forwarding (Router settings) and binding port 27015 to the local IP of the host machine.
