"You are signed in on multiple Xboxes" error

I would recommend changing your password here: Sign in to your Microsoft account (live.com) website. Once you have changed your password, even if the devices are still open with your account open as well, other people would not be able to access your account, as the server will now recognize your new password.

Moreover, I advise that you turn on the two-step verification so that when someone tries to access your account, even if he/she knows your password, he won't be able to do so. For more information, please click here.

If you have other questions, we look forward to hearing them from you.

You are able to talk to an sent on the Xbox website. So there's no need to worry okay.

Well, I fixed the issue last night. but the original issue has shown up again. Now the code 80048821 is showing up, and I can't get past it. It occurs after I put in the Microsoft account and Password, and click the "next" button, then a window giving me
the error code 80048821 shows up.

Is it a problem that all these error codes are showing up on my xbox? Or are they easy fix solutions and I just don't know how to solve them?

Would really appreciate the help, I paid good money for my Gold Membership and would hate to see it put to waste because of a couple errors.
