Can't connect to ipad

[cet033]

I am not able to share my screen from an iPad or iPhone any longer. When I try using a USB cord, connect to the wifi, tap screen mirror and then the name... I get the message "unable to connect".  I'd appreciate any help

Try system preferences—sharing—turn off AirPlay Receiver. Then try to share your ipad or iphone screen using airplay
