Wireless Charging stopped working; Could it be a software issue? (Samsung Galaxy S3)
Oddly, my receiver (NillKin) stopped charging the phone on the same day as yours did.  I have a Pixel XL (Android 8) &amp; this solution worked great!  ...until it didn't.  Try turning the phone off &amp; see if it will charge. Mine still will, but only if turned off.  I do notice that I have to be more precise with placing it on the pad than I used to.  Only thing I can think of electrically that matches the symptoms would be if there are multiple wires used in the loop &amp; one is either shorted or ground.  ???  Anyway, I ordered another one that should be here in a couple of days.
