can't join or start a party!

Modern Warfare 3 Forum

Hello, my friend and I cannot invite or join each others lobbies. After sending eachother multiple messages inviting the other person to join our lobby, it comes up with an error, this error reads "unable to join game sesson". we've tried restarting both our playstation, re-starting our routers, everything we could think of. Let me know if anyone else is experiencing this issue or knows how to fix it!

This problem has never previously occured, only began approximately 10 hours ago and since the beginning of it we have made no progress and are still unable to join eachothers lobbies.

this will happen if one or both of you have a "strict" nat type

we have never changed out nat types and had no problems regarding out nat type or how it may effect anything.
