Floodlight Cam Wired Pro no longer working

Hi all, Recently bought the entire suit of Ring products including the floodlight cam wired pro. The first one I bought simply didn't work - no power at all. I got a replacement, which worked for a day and now I get an offline message. I tried to reset it by pressing the button (which, by the way, is no mean feat as it's installed really high up), and tried to cycle it through the breaker. No light. Do not think there was a power surge or anything - anyone have any suggestions clue? Surely it can't be a second dud device? Thanks!
