just to clarify, my Tapo Cam c320ws was working normally showing on VLC, and others.  I enabled the Tapo Care trial and rtsp stopped completely.  I have tried everything.  So I disabled/canceled the Tapo Care Trial, rebooted the cam, and rtsp was back in operation, that quick.

I dont have, and have never installed, a micro card in this camera!  this is not a relative issue.  The Tapo Care stopped the rtsp. Doesn't matter what people believe or havebeen told  by their programmers.  No micro card was ever in this camera since the day I opened it as new.  This was not caused by a micro card. Not that a card doesnt cause rtsp to stop, just thatit wasn't  the problem in my particular case.

hooe this help other.  This was very frustrating.
