[RESOLVED] http-bind server responded with a status of 504 (Gateway timeout)

I can’t start a record session from my Jibri machine because Chrome can’t load http-bind channel,
obviously all the other resources (as HTML and JS) are loaded correctly

2020-04-09 13:33:20.986 INFO: [45] browser.leaveCallAndQuitBrowser() [2020-04-09T13:33:20+0000] [SEVERE] https://meet.mydoma.in/http-bind?room=test - Failed to load resource: the server responded with a status of 504 (Gateway Timeout)

This error only happens from the Jibri machines, all the other users can use the video conferencing system normally.

Nothing strange into prosody log and in Jibri log

I can reproduce the behavior opening the Jibri starting URL with my browser and see every http-bind request take 10 second to reply.

Resolved updating my Jitsi-meet istance with the new one (Videobridge2 + ngix).
