         using var media = new Media(_libVlc, 
            new Uri(uri)
           );
        
         // var uri = "/home/zcl/Videos/s0709.mp4";

If it works once and then not the second time, then it's most certainly a problem with live555 or with the server.

But in any case, VLC 3.0.9 is way out of date, so you're on your own.
