Make sure to read our doc, the blue box at the top explains it

If you still can't get it to work then let your friend try to invite you instead.
Otherwise open the app in your firewall and make sure the group is opened in game.

If nothing works port forwarding port 3074 (UDP) on your router will make it work

I have done all of those things and am still getting the error. Any more help would be appreciated.

JhonBondiola Hey I had the same problem with me and my friend. We couldn't join each other's game out of nowhere (to be clear we had just played the night before). we fixed it by closing the game and updating steam. for some reason, this fixed it even though neither of us has black ops 2 installed on steam. hope this helps.

TheFitz it's just a coincidence. What fixed it was trying again

I was having the same problem and what fixed the issue was updating steam even though I don't own an original copy of black ops 2 on steam.

TheFitz Hello! What do you mean by updating steam? Thank you!

Closing steam then launching the game should fix this!

I FOUND a semi-consistent FIX. When you invite your friend to your game don't leave the friend invite screen until they join the party. An example like, start your own custom zombies game -> pick a map -> press F to select your friend -> press invite and don't leave that window until they join. I found that to work more often than not.

We found that running steam in the background fixes the issue
