Ring spotlight Cam Plus power adapter is not working

I placed my Ring Spotlight Can Plus above my garage. I paid a contractor to have the Ring power cord go through a wall so it looks nice. After a few days the power adapter stopped working (the camera worked with other cords/adapters). After back and forth a with Ring Customer support I received the correct replacement adapter. I had to pay to run it through the wall. Unfortunately, the same thing happened. The Camera received power for a day or so, then failed. I took the camera down and it works with other cords. I checked the power feed going into the Ring adapter. It is working. The failure again is with the Ring adapter/cord. Has anyone experienced this? I enjoy the Ring community, but I’m ready to cut my losses.
