By the way, I completely agree with you both you guys' reasoning. Except that as I read Halo Waypoint posts, this problem was happening to specific regions (Brazil, UK and Japan) and not others. Also my NAT type has been open in all scenarios. This led
me to trying the VPN just to attempt to get War Zone to connect to a different server. And presto, it's working, whether its even to a different server I don't know. What I do know is that when War Zone thinks I am in HK, it works. When War Zone thinks I am
in Japan, it doesn't despite the MUCH better connection. I would hypothesize there's a larger issue with War Zone going on.

Ideas? I verified again this morning that War Zone matchmaking is not working while Arena is unless I use the VPN.

You do not understand the issue, you have to understand that there is modern warfare (not free) and modern warfare war zone (free)

For those who have a physical version, we can't access the original modern warfare campaign and other stuff from the main game that we purchased, we can only access modern warfare war zone, everytime we try to play the original modern warfare and not modern
warfare war zone it tell us that we have to purchase it. Even though we had paid for the physical version already.

Physical Game, You need use the disc to run the game.

War Zone is free mode, so you have not use the disc COD has War Zone only.

(If your physical game is non-free game, the system will not open the game)
