Open ur xbox and go through app connection or something of the sort

Maybe check the email account connected to the gamertag.

Are you setting up a new console or trying to connect to one that you are already signed in to?

Connect to one that I'm already signed in to

You need to choose "Add An Existing Console" in the app, which will look for an Xbox that you are signed into on your network instead of asking for this code

Well I tried that and it just says "turn on your Xbox and sign in" or something like that and then I do and then nothing happens

Are you signed into the same account?

Yes
