Solar Charger isn't working on Doorbell 1

I've got a Solar charger for our Doorbell 1 and it shows a status of "Not Established" in the Ring app. I've tried everything I can thing of to get this thing to work and so far it just appears to be an overpriced mounting device. Plenty of sunglight hits where it is mounted so not sure why it won't charge. I've attached a screenshot of the app status.
