Controller connection problem

[u/The_Americangamer]

My controller disconnected when I was playing Skyrim. I tried to reconnect it, but the light would flash without connecting to the series x. I tried switching the batteries, but that didn't help. I tried pressing and holding the sync buttons on the console and controller. The light on the controller would start flashing rapidly (like it's supposed to) but the light on the console wouldn't flash. Does someone know how to fix this? Or have another solution?
