Hi.
My friend just got WaW and I played with him MP with no problems whatsoever, but when I go ahead and try to play with him on zombies (Vanilla zombies, no mods) He cannot join. It says "Joining potential match" and then it says "Game session no longer available". I have hosted games in the past for other friends but it doesn't work. The only difference that happened is that i rebuilded my PC with different parts, that's it. I have port forwarded, told my friend to disable his firewall on the laptop and mine too, still does not work. I really don't know if this has to do anything but he's using home internet on wifi, the wifi is NOT the problem since the speed is 3.5MB/s. I am using my phone to tether my data through USB. The speed is 920 KB/s.
Things I've tried
Port forward
de-activate both firewalls
change ping 0 to 999
re-install the game
Nothing works.
I am using T4M and he's using vanilla (Don't think that actually conflicts)

I got vanilla to work but with mods it will not host. Neither me or my friend.
In vanilla it works fine if I or my friend hosts, apparently I left a port but now custom zombies won't work.
Thanks in advance
