Video Doorbell 3 Flashing Blue

My ring doorbell 3 is now constantly flashing blue. It says not connected to the internet. my internet is fine as are all my other ring devices connected. I have tried with 3 different batteries, tried putting into setup mode and re-installing which worked for about 5 minutes. it then flashes again constantly. it will no longer go into setup mode with the orange button just constantly flashing blue.
