WHY AM I GETTING SIGNED OUT?

Hi, more often than not if you delete your profile,
be sure to delete profile only, then clear the system cache three times and download your profile again this issue will stop happening.

The problem is not my Xbox Live connection...it's my profile. When I launch a game it signs me out. When I leave a game it signs me out. Why?

It doesn't seem like it is a hardware issue. I wouldn't think about of sending in your console for repair, as there are many solutions that may fix the problem.

Assuming you are using an Xbox 360, I want you to do three things.

1). Delete your profile.

To do this,

Navigate to the Settings tab from your Xbox Home Screen. Click on System. select Storage and click on Hard Drive, click on profiles, and select the profile that is causing issues. Now click delete, and select delete profile only.

2). Clear your system cache -

To do this,

Navigate to the Settings tab from your Xbox Home Screen. Click on System. select Storage and Highlight the Hard Drive, press Y on your controller and select Clear System Cache (Don't worry, your personal content will not be deleted).

Now Shut off the Xbox completely, and turn it back on.

3). Re-download your profile

To do this,

On the Xbox Home Screen, navigate to the Social tab, click on Sign in or Out, scroll all of the way to the right. Select Download profile and follow the on screen prompts. Make sure the Save Password is checked in the box, if your on a personal Xbox.

Let me know if this works for you.

I am sorry to hear that.

Are you trying to login via the website?

This has been affecting more users since yesterday.

Have you tried to use a different browser or your browser's incognito/InPrivate mode?

There is no official confirmation yet, but this might be a problem with the web servers.

On the Xbox Status page, it's not mentioned yet: https://support.xbox.com/xbox-live-status

I reported the issue and await a response, I will update this post as soon as I have new information.

For now, what has worked was logging in via the Xbox Mobile App or Xbox PC App.

Let me know if it works!
