Ring Pro went offline on June 19, 2020. Tried any and all steps to resolve. Slow flashing white light when attempting to reset and perform setup. Cannot join Ring-xxxxx wifi network when prompted. The device is not running setup correctly. Many users seem to be affected by the same issue over the June 19-June 22, 2020 timeframe. Support sending replacement. Hopefully not refurbished device. This device is too costly to have this happen. I suspect a bad firmware update. They assure me that firmware updates cannot cause the types of problems <lol> ok…
Did you try removing the ring an unscrewing the power hleage off until the light/ring goes dark)? Mine did this recently ‘showed offline’ and wouldn’t connect during setup as you explained. After power cycling mine was back online. I was having other issues (dead on ding) so support is replacing mine but in this was the first time I had seen it go offline.
i have good voltage though and even tech said the logs show steady (non fluctuation voltage).
