: Multiplayer test is failed
Hello,

As a frequent international traveler who runs into NAT issues I can definitely understand your frustration!

I would actually suggest you goto your advanced router settings and just double check that the xbox did not accidentally get added to the firewall of the router.

If you look through your router config there is typically a tab for security or something that that sort which will contain the banned devices.

Just a suggestion because although rare sometimes failure to connect at all, after messing with port configs can trip built in firewalls. Hopefully this helps. If not I would be willing to assist further.

As for ports: I would reccomend

either UPnP or I have had success opening the following ports for an open NAT.

UDP port 5060

UDP port 5061

UDP port 3074

:)
