Webrtcbin not working properly in gstreamer 1.22.2

I am using webrtcbin element to live stream on web browser, but it is showing core dumped. This is my pipeline : rtspsrc location=rtsp://172.138.0.2:17600/y1 ! watchdog timeout=300000 ! rtph264depay ! h264parse ! rtph264pay config-interval=-1 mtu=1200 ! queue ! application/x-rtp,media=video,encoding-name=H264,payload=96 ! webrtcbin bundle-policy=max-bundle name=sendrecv

I am suspecting the issue is because of the webrtcbin element as it is not able to send data. I think webrtcbin element is not able to do negotiation and send and receive ice candidates . please see this image which has logs for this.

I have also suspected libproxy may be the reason , but this is not the case!

You have already asked this question twice on GStreamer gitlab with the same answer by two different people. This is a problem in your environment and libproxy does not like it.

I am going to close this for that reason.
