As the title suggests, I can only play with my friends one time for each game. For example, I played Payday:The Heist with a friend one time, then after that the game was like "NOPE, YOU CAN'T PLAY WITH HIM AGAIN, SESSION ISN'T AVAILABLE". Again the same problem happened today in Operation Flashpoint:Red River. The game cockblocked me again "NOPE, YOU CAN'T PLAY WITH HIM AGAIN, HURDURHUR". Does anybody else have this problem? I tried fixing it by turning my ps3 off and on, but the thing still wont connect to each other.
Emerald is right, in many cases its the other person's net, but there are times when the server the game uses acts up. Soul Calibur is a big one known for that. ask your friend what his/or her Nat is. Nat 1 would be best but if your still having this problem with a Nat 2 then it's more likely the game server.
