majin93 0 Posted December 29, 2012 My devkit ip is on DMZ, tested ports with F3 and it went well. If i start BO2 TU5 with F3, i join in a group with F3, i can see other's ppl matches but i cannot join at all! The error is "Unable to join game session", the only time i can join is when someone is in the lobby ALONE, but even there as soon as he starts the game, my devkit freezes. I made a friend test this and he has the exact same problem, i don't know what to do. We tried playing on XBSLINK and there is working fine. Quote Share this post Link to post Share on other sites
