I'm playing Dying Light 2 on Series X and trying to connect to someone else on Series X. We are at the point where co-op is unlocked, our NAT types are open, we both have the DLC installed, have restarted our internet, have redownloaded the game, etc.
Yet when I try to join I get "The game session you have tried to join is no longer available".
I'm at a loss, because I have looked online. Google, Discord, and Reddit. Nothing comes back. I can't find anyone else with this issue. I just want to play the game co-op but no amount of troubleshooting is fixing it.
