Teredo address for Xbox app issue FIX

I had the same exact issue, I hated messing with the Teredo Address issue, unfortunately you need an Open NAT to be able to obtain the teredo address without issue, I suggest getting an easier gaming router or better ISP If you can't get it fixed.

If you can’t hear your friends online, or you can’t join or host an Xbox Live multiplayer game, go to
Network > Settings in the Xbox app and check
NAT type.

If it says Teredo is unable to qualify, your PC is unable to obtain a Teredo IP address.

Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity between devices behind routers that use network address translation
(NAT).

Failure to obtain a Teredo IP address can occur when there’s an issue with your Teredo adapter, when a device on your network is blocking the Teredo protocol, or if there’s software installed on your PC
that’s disabling Teredo functionality. Without a Teredo IP address, you’ll be unable to use party chat or do multiplayer gaming on Xbox Live.

Same, I can't connect to xbox live parties from the app because it can't find the teredo address.
