Plutonium

I've been searching for people to play BO2 OR IW5, to try to see if IW5 works in private matches, to play zombies and multiplayer in BO2

I tried to play private matches with a friend in IW5 (we follow each other in plutonium and we even live in the same state), when i tried to join his match it just said connecting (same thing happened when he tried to join my game), i waited a long time and it just wouldn't let me in, is there anything i can do to play private matches?

same, i need some friends to play T6 and IW5, i'm kinda trash at the game and die a lot in multiplayer, so wanna find some friends to chill and have some fun in some party games or sm
