: Xbox One won't connect to multiplayer
Hello EPICONLP,

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).

Sometimes, you just need to go into your router to activate teredo, or "Teredo tunneling". If it is already activated, turning that setting off and then back on can help.

Don't forget to try the troubleshooting in that support article given to you by Amber above. Click on that link, and select the teredo error to begin troubleshooting.

Hope this helps!

:)
