Controller won’t sync and connect to Xbox

Have you tried doing a power cycle to reboot your console?

After you get it to sync to your console again I would check that the firmware of the controller is up to date.

Hopefully this will help!

Occasionally, this happens, like the Ambassador mentioned, you can always do that hard reboot, and it should fix your issue.

So recently my Xbox wasn’t connecting to the internet at all. The servers weren’t shut down, the Xbox would just not connect to the wifi. The Xbox gave me a notification that it had to do with a problem with the connection of the controller. The
controller would have to be restarted and connect to the wifi. It restarted the controller but it wouldn’t connect to the Xbox. I tried syncing the controller like when I first got it, I tried other controllers, and I even tried using a cable to connect the
controller to the Xbox, yet it still won’t connect.

Other controllers works?

All controller don't connect/work? Or only one? (maybe your preferred controller)

Yes this is the only game , and yes the Xbox has Xbox live and is connected to the internet, it won’t let me sync the game either so I don’t know what the issue will be

Yes, this first occurred last weekend. The console has been unplugged for multiple hours at least twice. I’ve changed all batteries in controllers as well.

The console hasn’t worked for several days, tonight was the first time I found this forum to ask questions.

Thank you
