TCP is OK. TLS gives me the erro "not-negotiated". What to check?

[Rodrigo Pimenta Carvalho]

Hi.

I'm a beginner with GStreamer and trying to understand some basic concepts
about TLS negotiation.

I have a rtsp server and a client. The client gets video from the server
without any problem, when server and client are using TCP. 

If the server and client are using TLS, the client gets an error related to
"not-negotiated". What could be such problem? What should I to check in the
server?

When TCP is being used, the client command is:
--------------------------------------------------------------------
gst-launch-1.0 -v -m --gst-debug-level=3 rtspsrc
location="rtspt://f9hE2ymDyVAK:YljYgExxh4ft@192.168.28.33:2554/h264/ch1/main/av_stream"
! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink


When TLS is being used, the client command is:
---------------------------------------------------------------------
gst-launch-1.0 -v -m --gst-debug-level=3 rtspsrc
location="rtsps://f9hE2ymDyVAK:YljYgExxh4ft@192.168.28.33:2554/h264/ch1/main/av_stream" 
tls-validation-flags=generic-error ! rtph264depay ! avdec_h264 !
videoconvert ! autovideosink

And the error is:
ERROR: from element
/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0: Internal data
flow error.
Additional debug info:
gstbasesrc.c(2933): gst_base_src_loop ():
/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0:
streaming task paused, reason not-negotiated (-4)

Any hint will be very helpful!
Best regards.
