Ring 3 misbehaving(not recording) between 12 midnite and 6am again

This issue is frustrating; Nothing has changed regarding lighting, settings, etc. But periodically, my Ring 3 is not recording events during those hours. This has been going on now for the last two-three nights. I know movement is happening because I hear cars going up and down my one-way-in, one-way-out street. No settings are changed. The lighting in my small neighborhood stays the same. Why doe this keep happening periodically?
