Does REST API work on demo server?

I use https://janus.conf.meetecho.com/janus to test my environment, but currently I can’t create session for streaming plugin, when I use REST API command, the result is error “reason:-Janus Server not live or incorrect url/path specified”

At the same time, websocket connection works well

So, is REST API still supported or it is just not available on demo page anymore?

Please don’t use the demo server for anything other than the online demos. If you want to test Janus and the API, use your own Janus instance.

Yes. I have setup janus server in AWS. How do I know whether stream is receiving rtp data? Is there any API?
