2nd gen cam and solar

Hi all. I am having issues with one of my 2nd gen cameras. Three of the cams have been running on solar for almost a year with no issues at all. Recently I decided to connect cam number 4 to solar. I bought tgr same panel as used with the other cams ( not a ring panel as I had read bad reviews on them). Cam number 4 will not connect to the solar panel at all. I have tried the usual reboot the cam, no change, re-set the cam, no change. The panel is working as I plugged it into two of my other cams to check and both show solar connected within a few minutes. The contact us section of the Web site is a joke as you type in the query and it takes you back to the beginning page every time I click submit. I have tried all I can think of to get the solar connecting without success, if anyone can help it would be much appreciated, I’m beginning to think the connector on the cam is faulty but as I cannot contact Ring I doubt I will ever find out. TIA. ** UPDATE ** In the last two days the camera in question had begun turning off the motion detection all by itself, i am now convinced that this cam is faulty.
