Controller not connecting to Xbox

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)

Hi and Sulute

sorry to hear.

If this controller was previously connected to the console but is no longer able to connect, you should repeat the connection process using the console’s connect button.

For info on how to connect your wireless controller to an Xbox One, Xbox One S, or Xbox One X, see

Connect a wireless Xbox One controller to your console.

If this does not help try "Troubleshoot your Xbox One wireless controller"

Hope this helps
