So I decided to play coop with a friend on halo 2 and everytime I start a mission it says connection interupted leaving lobby. I want to specify that i played the first mission with him without having any problems that i go to eat something came back and started the second mission and this happened.
Any ideas why this happened
P.S. I tried to verify integrity of the game files, to restart computer, we tried to play the next day, restarted pc but nothing worked
