Can't add back my fifth Arlo Camera

[SCHow]

I currently have (4) four Arlo (original) cameras conencted to the VMB3000 Base Station, but I can't add back my 5th camera.  I had 5 working cameras for >4yrs, removed one and now when I go to add it back via new device set-up (on app and website) it doesn't find the device.  I've tried +10 times via as well as the original way of syncing camera to base station, but no luck.   I know the camera is still connected to the base station, because when I arm the system the 5th camera detects motion and turns on.  However, I have no way to view or control from the app.  How do I reconnect my 5th camera?  Thanks,
