My Xbox controller will not connect

It's doing the same thing with the controller my xbox came with but not with my cousins controller when I connect it to my xbox and yes it appeared when my power a controller was connected

I have 0 controllers connected to my Xbox because I can't connect any. It isn't just my one controller that won't connect, none of my 4 controllers will.

Ive also tried on other controllers connected to my xbox, reset the xbox and it still didnt work. When i connected to my sisters Xbox/controller it worked

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)

The button doesnt click. I used this cord to connect my controller before but now my controllers broken so i had to try my sisters. When i connect that controller it does turn on but stays connected to her xbox.
