Doorbell no response

So my doorbell is not reacting to anything. Cant connect through app. Tried to troubleshoot through the app but my ring is not lighting any way in the described solution. I have connection to my other ring products on same address. No problems. Only the doorbell for 3 days now. I tried to unplug and replug the power with a few minutes delay ofcourse. I tried pressing the reset button inside the case. No reaction. What to do?
