iPhone 11 pro suddenly did not charge on my Samsung wireless charger or my iOttie wireless charger

Beginning October 14th, I noticed that my iPhone 11 pro was not charging on my wireless charger (Samsung), but had before. It also did not charge on my iOttie wireless car charger. After removing the case (which made no difference), than powering off and on the phone (which did work), I am concerned about the root problem. My chargers work with other iPhones in the house, so definitely something just affecting the newer iPhone (11 pro in my case)
