light flashing blue and white after battery recharge

When I place the charged battery into the the camera the light in the base flashes blue and white. I have tried to perform a hard restart by holding the button at the top of the camera for over 30 secnods. This results in the light going off, but as soon as i take my finger off the button the light starts to flash blue and white again. I have also removed the device from my ring app, in the hope of adding the device again but as the light is flashing blue and white it is not allowing me to connect to the ring network. Hence I am unable to add the device to my account.
