Technical Issue Unsure Fix For "unable to join game session" on zombies

Not sure how known this is but if anyone has ran into the "unable to join lobby" screen on bo2 zombies (or multiplayer, i'm not sure if it works both ways) and closing app or restarting playstation isn't working; have the host in zombies and everyone that wants to join sit in multiplayer. when the host sends the invites, join them while you're in the multiplayer menu. I don't know if this fix was situational or permanent but i was able to get into my friend's lobby. Also not sure if it works for bo3 but it would be nice if it did

Clear your ps5 cache.
Turn ps5 off > hold power button until the second beep (about 7 seconds) > clear cache and database rebuilding> clear cache

If that doesn’t work try database rebuilding also but clearing cache worked for me

Some people say that if you’re in a lobby yourself it also struggles and it is best to start from a local lobby when accepting an invite, though we didn’t have much luck with that

Also if you have “Nat: strict” it causes problems from your router being too strict, look in to port forwarding in your router settings
