How do I get my Xbox one controller to connect when it won’t

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)

What type of problem are you having with your controller?

MY CONTROLLER WON’T CONNECT TO MY CONSOLE OR PC -> it doesn't apply. the controller does connect to my pc

I CAN’T UPDATE MY CONTROLLER -> it doesn't apply. Xbox Accessories says it is up to date

MY CONTROLLER DOESN’T FUNCTION CORRECTLY -> somehow it doesn't. let's take this option

MY CONTROLLER WON’T POWER ON -> it doesn't apply. the controller does power on

SOME OR ALL OF THE BUTTONS ON MY CONTROLLER DON’T WORK AT ALL -> it doesn't apply. All buttons do work correctly

SOME OF THE BUTTONS ON MY CONTROLLER DON’T WORK AS EXPECTED -> it doesn't apply. All buttons do work as expected.

so:
Xbox One Wireless Controller Solution doesn't have an option for the "stops working" symptom

• To configure the Xbox Elite Wireless Controller Series 2, get the Windows 10 May 2019 Update (or later) and make sure your PC has the latest fixes.
  
  See how to get updates.
• The Xbox Accessories app won’t detect your controller if you’re using Bluetooth to connect to your PC. Connect your controller using Xbox Wireless, or plug the included USB-C cable into the back of the Xbox Elite Wireless Controller Series 2 and plug the
  other end into your PC. For more info, see
  How to connect an Xbox One Wireless Controller to a Windows PC.
