Ring Pro Base station keeps saying there's a loss of power and going to battery

My Ring Alarm Base Station Pro connected to a fiber ISP via Ethernet cable at my other residence started reporting power losses every 3 to 5 minutes, then had the power restored. This occurs all day!! **Background:** The unit is plugged directly into the outlet and the electrical panel has a whole house surge protector. The electrical usage for the whole house is 102 watts (since no one is home) (Sense smart panel reported no issues). Everything has been operational with no issues for the past 5 months with no changes and it started occurring in the early morning hours a couple days ago. **Troubleshooting:** Called the electrical company and they came out to verify nothing was wrong. Rebooted the unit remotely several times. Ring Technical support also rebooted the unit While I'm waiting to hear back from Ring Technical support (last issue took 9 months to resolve), does anyone have any advice.
