Arlo Essential camera does not connect after reading the QR Code

[Korculaner]

2 of my cameras run out of power. Maybe 3 - 4 days. I took them off and tried to connect, did not work. I reset the camera (15sec, amber light etc), than on the app I went through the motions entering network and password (same as before). I pushed the button below the cameral, blue light blinks, I have the camera read the QR code, camera chimes. Camer blinks 4 - 6 times and shuts of. 

I am on a dual band network, so I disabled the 5GHZ band ( however, it worked before). Reset the router and the camera again and same problem. I did the reset and reconnect process at least 40 times (no kidding...!) - does not work. Frustrated because everything is the same setting and nothing changed.

Battery is charged - no Microwave - no eval spirits just a pain.... Any tip greatly appreciated!!!

Update - after I continued to reset the camera and go through the set up, scanning the QR code for at least 20 more times it suddenly worked with one camera. Everything is the same, there was no power failure or router reset. Now I am working on the same issue with an another camera. I assume it is just simply luck if or if not the camera connects...  My dear ARLO executives, you should work more on solutions and customer service! Your corporate jet needs to get paid for and it gets paid by customers - don't forget... !
