It's just "one of those tings" that seems to happen in game, no fix that I know of.

in borderlands 2, gearbox software found out that in most cases when people couldnt party up, both parties were attempting to connect to the LAN IP instead of the individual computer the parties were playing on. they fixed this with a patch by modifying the game to open up its own ports so that it will connect no matter what (with lag if i may add). Treyarch doesnt seem to have figured this out yet, or a fix for black ops 2 is simply taking alot more time.

You may not have the seasonpass/revolution/nuketown/dlc map that you or your friends have or are playing in therefore, you are unable to join that specific game or session. Someone else can clarify that.

This problem occurs because the NAT function to be activated (in restricted mode, moderate), also happens because some ISPs despite the nat being open porvedor blocks some ports, it is necessary to contact the provider requesting the unlocking of doors down because without them it is impossible to open a game for friends.
Besides this in order to play the BO2 is recommendable to have a download speed of 700kbp/se at least 128kb / s upload matches to open for friends.

Black Ops 2 ports are the same for MW3:
UDP: 36081, 3074, 3075, 3478, 27000 to 27030
TCP: 80, 81, 443, 3074, 5223, 27014 to 27050

As the doors for you to know which is blocked so make a test of the internet via TCP and UDP ports.
