My friend cant join me
-
my upnp is enabled, his upnp is enabled and we even tried hamachi
works fine in multiplayer but while playing zombies i can host in nuketown, tranzit and die rise other than that is just wont connect and either "Joining session" then disappears or incompatible ui version
what should i do?
Also tried hamachi, still doesn't work -
The imcompatible UI version is a known issue regarding the difficulty setting of the map. If you're getting that error, switch the difficulty and it should work.
