Teredo and Nat Type on the Xbox S Series?

So, hi

I recently bought an Xbox S series and noticed that my Nat type can't be determined

In addition, my Xbox is not able to get the Teredo IP

What can I do?

Teredo shouldn't have that much to do with Nat in the strict sense. Maybe you like to google one like the other.

and: Teredo is a security risk, the service could also be blocked in the services.
