“This accessory may not be supported”

I have tried multiple different chargers, brands of chargers and even methods of charging. No matter which cord I use though, I keep getting a message reading “This accessory may not be supported” After doing some research, I found that usually this means the cord isn’t verified by Apple, however some of the cords I was trying were Apple manufactured cords. If anyone knows how to fix this or has any recommendations about how to go about this, please don’t hesitate to help!
