Arlo pro 2 camera stopped working

[Naot]

My camera just stopped working today and went offline. The other 4 cameras are still operational. I attempted to take out battery, wait more than 15 seconds before plug it back in. The front blue light went solid for a few seconds. When plug in the USB cable, the blue light blinks a few times. I attempted factory reset by holding sync button for more than 15 seconds ; however, no amber light showed up. The camera does not give any respond at all. Please help.

There's really no reset on the Pro2 cam...

Other than pulling the battery for a few seconds.

Pull battery, after 10 sec replace.  The cam led should flash blue once.

Press base sync button and then press the camera sync button while within 3 ft of base

Base led should blink, camera will flash fast blue if the sync is good.
