Spotlight cams won’t connect, but powered on

I have two spotlight cams that stopped connecting within several hours of each other. One I bought last December, and the other back in March. They are connected to WiFi, and the batteries are charge, but there’s a solid red light showing on the inside where the batteries are of each camera (not blinking). They still light up when there’s motion and are getting power from the batteries, but won’t connect. Help!
