Deepstream enter RTSP error

Please provide complete information as applicable to your setup.

**• Hardware Platform (Jetson / GPU)jetson nano
**• DeepStream Version5.1
**• JetPack Version (valid for Jetson only)32.5.1
**• TensorRT Version7.1

error: No supported authentication protocol was found

This may be caused by your RTSP server, please check your RTSP server.

my RSTP stream is OK, I can get it through opencv, but not gstream

opencv is quite different to gstreamer.

You can use gst-launch pipeline to try your rtsp stream first.

gst-launch-1.0 --gst-debug=rtspsrc:5 rtspsrc location=rtsp://xxxxx ! decodebin ! fakesink sync=0

Still not, my original RSTP has been skipped, and the error is reported as follows:
