Solar panel won't charge ring battery

I recently started having an issue with the solar panel not charging the camera. I thought it might be with the solar panel, so I bought a new panel. Turns out that wasn't the problem, so I returned it. I can get the panel to start charging the camera after a few reboots. I was able to get it to charge from 90% to 100%. Then the next day it doesn't charge again. I'm guessing it might be software related. It only charges when I have the message below it saying the solar panel is connected. The message saying the solar panel is able to charge disappears the next day.
