Secure rooms , guest lost video and audio

good morning,
I have installed and configured jitsi on a debian 9 server, it works perfectly, it is behind a firewall so use this note, # advanced-configuration, to avoid problems with more than two users,
I have applied room creator security,, but the moment I get to step
var config = {
hosts: {
// XMPP domain.
domain: ‘’,
anonymousdomain: ‘’,
The security part works, but the problem returns with more than two users connected, when the third one enters, video and audio are lost.
simply commenting the line “anonymousdomain: ‘’,” can connect more than 3 people correctly … but with a password, can someone help me?
