Sounds like a networking issue. You or the guy you are joinin on or both need to perform port forwarding and open your NAT type. Google how for your particular router/firewall.

Obmar has it right, but once in a while Joining still gets screwed-up and if that's the case try joining another in the Party or restarting BO2 as a last resort especially if there was a recent update to Steam or BO2. I run Open NAT in the form of DMZ Host to my Router.

Thanks for providing the link Monba1!

Since you are joining to a group, this could be potentially an issue with someone in the groups connection causing issues.Also, are you attempting to join while they are in game as this message could be showing if you attempt to join a full lobby. ^JG

Yep, Joining an in-progress game could be a (the) problem, but in that scenario you're not joining in as/from an Invite, and is often in conjunction with a 'Server is Full' error message or potentially being tossed-in on the opposing side. Generally, we pick the person with the lowest Ping, greatest bandwidth to Host and one with an Open NAT. Occasionally, one guy's the Host but others Join someone who's a Party to the Host 'if' there's a problem; Friend of a Friend.

Generally, we get this all worked-out before we get into a game.
