JaaS Live Streaming not working as intended

We are using JaaS for a rather large event and we rely on Live streaming so we can support more users. Over the weekend we’ve started experiencing problems when using Live streaming. Very often it happens that when we call ‘startRecording’ command with a custom rtmp url, it takes very long to get any feedback, then we get an error saying Live streaming failed to start.
The problem is that jibri joins the session and live streams the whole thing but we never get a callback for that through iframe api nor is it visible in the UI. It is also impossible to end live streaming because we get an error saying that no recording/live streaming session is found.

I’ve also opened a ticket directly on JaaS (ticket JAASF-526) but I did not receive any feedback yet.
