BBB API working but button join in Greenlight not work

[Gotppsn]

Hi I try to use API to create automation to create a meeting room
API and Server Rooms status is Running Normal
but am trying to join the Class via Greenlight front page it does not work
it shows up "The meeting hasn't started yet."
but the room is running

Do you have any ideas?

Hi, i have the same problem.
It is possible to join a meeting via the Nextcloud API.
But not via BBB website.
I have already reinstalled BBB including Greenlight but the error remains.

Hi,
I could be wrong, but I don't think it's that simple.
According to BBB's Security Model, you have to send a checksum with ever API call.
Besides, I would guess that, every time you start a room through GL, a new checksum will be generated, which will not be the same as the one you specify via other means (APIMate, Nextrcloud API, etc).
Just my 2 cents.

Regards,
J.

look in nginx logs /var/log/nginx/bigbluebutton.access.log and see what exact params are being sent on the create call when you start a room in GL. look at the custom meta_ params, the start is doing a create, and then a join together to get into the room.

I see these params and callbacks when i start a GL room.
&meta_bbb-origin=greenlight
&meta_bbb-origin-version=3
&meta_bbb-recording-ready-url=https%3A%2F%2Fxxx.xxxxxx.cloud%2Frecording_ready
&meta_endCallbackUrl=https%3A%2F%2Fxxx.xxxxxx.cloud%2Fmeeting_ended
&moderatorOnlyMessage=xxxxxx

Also when the create call is made im sure the internal meetingID is sent back in response and most likely this is stored in postgres and may be what is used to enable entering a started meeting. Just guessing here, but you may need at add the this is postgres to enable joining in GL

In my nginx log /var/log/nginx/bigbluebutton.access.log i didn't see anything like this.
This is the output when i start a room in GL:
