Trouble joining a friends lobby in Black Ops 4

A few of us had quite the similar issue last week "lobby not joinable" be sure your game is up to date and do a full shut down in the console settings.

Can you try to do this again, the MOMENT it happens go to settings, Network, Network settings and tell us what your NAT type is?

Hey there Mackenzie!

Sorry to hear that you're experiencing this difficulty with getting in lobbies.

Sometimes things like this could be a problem with the game's servers, but agood course of action for you to take for this kind of problem would be first to try power
cycling as outlined in
How to restart or power cycle your Xbox One console.

If that doesn't clear up the issue, there's also this little trick that I like to do that resolves a bunch of general problems that you may have concerning your console
and might help. When you get a chance to goSettings>Disc & Blu-ray>Blu-ray>Persistent storage
and clear it 3 times. After doing that, go to
Settings>Network>Network Settings> Advanced Settings> Alternate MAC address
and clear that alternate MAC. The console will say it needs to restart to apply the change, so let it do that and then try to download your profile again.

Hope these troubleshooting steps help out, be sure to let us know.

Thanks for reading!

black ops and forza 4! for black ops it says joining game lobby, testing available matches and then it starts all over again, eventually it says (error! session has expired, please again,)

I really wish the two teams would work together. Black Ops had a far superior menu/party system. I can't even click on a friend and join the lobby within the game; with Black Ops I didn't have to wait for an invite from the XBL dashboard system.
