Recording Unavailable although Jibri is running

I’ve installed Jibri according to the tutorial (TUTORIAL - How to Install the NEW JIBRI)
My Jibri log contains the below error

2021-08-04 11:15:49.340 WARNING: [27] org.jitsi.xmpp.mucclient.MucClient.log() [MucClient] error connecting
org.jivesoftware.smack.SmackException$ConnectionException: The following addresses failed: ‘’ failed because:

use private-ip of the VM on which prosody is installed in jibri.conf(xmpp-server-hosts = [ "private-ip" ]) instead of domain-name. also open port 5222 on prosody server(VM) firewall for private ip only.
