Lobby issue with user when join the meeting

When the moderator activate lobby option, users can not join on meeting.

Sequence of events:

  1. Moderator joins a room with JWT token.
  2. Moderator turns on Lobby option.
  3. User try to join the room.
  4. Room iframe appears and disappear within 1 second.

In console I get the following errors:

<Ete._onConferenceFailed>: CONFERENCE FAILED: conference.connectionError.membersOnly [meetinterview]room_6@lobby.meet…

[features/base/connection] conference.connectionError.membersOnly

Here is how I set up guest jwt

var options = {
            roomName: `meetinterview/room_${$slot}`,
            width: '100%',
            jwt:$jwt,
            parentNode: document.querySelector('#jaas-container')
        };
$jitsyApi = new JitsiMeetExternalAPI(domain, options);

What is the error in this case, the members only logs are normal.

The error here is the video call for users not starting. As the iframe appear only for 1 second.
I managed to fit it by adding:

 var options = {
            roomName: `meetinterview/room_${$slot}`,
            width: '100%',
            jwt:$jwt,
            parentNode: document.querySelector('#jaas-container'),
            configOverwrite:{
                prejoinPageEnabled: true
            }
        };

This doesn’t seem correct… You should see the error when it disappears
