suggest that you call Xbox support as this might be a bit stickey to solve by yourself

Hi BoubuhL8r! My name is Ricardo an independent advisor ready to help you with this situation!

Log in in the site it's being request, probably there's some suspicious activity on your account or you haven't completed the registration process for the account

What are you actually trying to do? Support can probably still access the account, but if it's permanently banned there would be no reason for them to.

Hi there,

You could start by trying power cycle your Xbox One console, or run a Xbox
One Network Connection Test. If you have an internet erro, just follow the steps in that link.

Hope it help, let us know!

double check that your e-mail is written right and that you have an active connection to x box live.

hope i could help
