The gstreamer WebRTC sendonly example works only locally. The examples are deployed on machine with a public IP address. I am using gstreamer 1.20 on ubuntu 20.04LTS.
Furthermore, in the browser of the local machine where sendonly is deployed, when I use 127.0.0.1 the example works. However when I use the public IP of the machine, it does not work.
When it does not work, the sendonly program does not receive an SDP answer (soup_websocket_message_cb)
