Cannot Add Device of VMB4000 Arlo Pro Base Station

[otter449]

I'm seeing an issue like in https://community.arlo.com/t5/Arlo-Pro-2/Arlo-Base-Station-VMB-4000-known-outage/m-p/2332032#M61977

and https://community.arlo.com/t5/Arlo/Cannot-add-VMB4000/td-p/2412090

I have a VMB4000 that was working for many years. Some combination of recent new phones, Base Station Reboots, and Base Station Resets, and now I currently have LEDs:
Power: solid green

Internet: mostly solid green, occasional blinks (using wired ethernet)

Cameras: solid amber. unsure if cameras are synced now, but I'm starting with the Base Station

Using Android Arlo Secure App and My Arlo web page, I keep getting No Arlo devices found when trying to add a device.
