It won't let me sign in on my xbox

Hey there,

Sounds like there could be an issue with the account or there might have been a small outage that caused this. Are you able to sign into your account on
account.live.com without any issues?

Let us know!

Hey there -

What is the error message and/or code (XBOS-0000 or 0x00000000) that you are experiencing? Having that will help us better understand what the issue may be. That said, you can try holding down the power button for 10 seconds and signing back in and if that
still doesn't work, the next thing I'd recommend trying is
removing your Xbox Live profile from your console and trying again.

Keep us posted.

The problem still persists, it might just be an issue with the xbox itself at this point.

I'm sorry it didn't work out.

Please try the following steps:

Go to your network settings and in advanced options change the DNS to primary 8.8.8.8 and secondary 8.8.4.4

Remove your account from the console

Press and hold the power button on the console until the Xbox turns off completely.

When the indicator lights on the front panel of the Xbox turn off, unplug the power cord from the back of the Xbox.

Wait at least 30 seconds.

Reconnect the Xbox console and turn it back on.

Re-enter your account and test if the error persists.

Hello!

Hope you are well. I'll be glad to assist you.

I'm sorry you're experiencing these issues.

Please try to test connecting your console to another network and check if the same problem occurs, you could configure your smartphone as a Mobile Hotspot and connect your console to that network.

Let me know if the behavior is the same.

Best regards!
