Spotlight battery camera intermittently reports solar panel not connected

I have two spotlight battery cameras, each with an attached solar panel. The cameras reliably are charged to almost or fully 100% with the solar panel reported as “connected”. However, at times the panel on one or both cameras reports “not connected”. The reporting camera continues to report full charge so it’s likely the solar charging is working during this “not connected” situation. I’m sure the connections are secure and both cameras and panels are properly functioning. Anyone seen this issue and know the reason and/or solution?
