Xbox sign in problems - Sign in issues : xbox

The only thing that I haven't been able to do is to find a way and put a teredo tunneling adapter for network adapters, I dunno of this is the problem, but for a time through some commands from powershell and by enabling teredo from registry, there was a teredo connection, but the problem remained.

I will really appreciate it.

You can try logging in on the official Xbox website to have a check.

The Xbox App May Display A Notification That Says Your Signed In Account Is Different From Your Store Account.

In most cases this means Xbox users may not be able to sign-in to the Xbox profile, with players potentially being disconnected while signed in.

Ensure that the account has access to the sandbox your title is published to.
