How do I fix Xbox Sign In error 0x800c000b?

1: Check Xbox Live services status report

First, make sure that Xbox Live Services are up and running.

Due to maintenance or a temporary server error, the services might be down and thus you’ll be unable to access your Xbox Live account or use the online-based features.

Also, this is the most common reason why sign-in errors occur in the first place. You can see the Xbox Live Services Status Report, here.

2: Power cycle the console

Most of the problems with any Xbox console, starting with Xbox to Xbox One, are resolved with a simple reboot.

Hard reset or power cycle of the console usually fixes all kinds of system halts.

There are rarely some complex reasons behind the sign-in error like this one, so resetting the console should help on most occasions.

Follow these steps to Power Cycle the console:

1. Press and hold the Power button for 10 seconds or so.
2. Wait until the console shuts down.
3. After a minute, turn on the console again and look for changes.
