Cannot join conference with multiple participants

Seyma · December 9, 2020, 6:32am

Dear Community,

I’m new to Jitsi. I have it setup and running for a while without any issue until today I am not able to join the conference with multiple participants. I tested by creating a room with only 2 users without any problem. But when more than 2 users join the room, some of them become idle and disconnected. Their audio and camera were terminated. Does anyone used to face similar difficulty? Or kindly advise what should I check?

Below is the jicofo log.

==================

Thanks and appreciate for any input.

Are you saying you were able to host meetings with 3 participants before and suddenly you can’t anymore?

Seyma · December 9, 2020, 7:18am

Dear Freddie,

Yes, that is correct. we used to host meeting with up to 10 participants before.

Any advice you might suggest so that I can check?

Regards,
Seyma

Freddie · December 9, 2020, 7:22am

Well, usually when you can’t host a meeting with 3 or more participants, it’s because of a firewall issue. Check to make sure there’s no firewall blocking any of the required ports. Check in particular to make sure port 10000/UDP is open and appropriately forwarded. If none of that works, then take a look at the Advanced configuration section of the Quick Install Guide.

Seyma · December 9, 2020, 7:33am

Dear Freddie,

Thanks for your suggestion. I am checking that and will share the progress.

Regards,
Seyma

Seyma · December 9, 2020, 9:00am

Dear Freddie,

I had a look at firewall and all required ports are open. During my investigation, I notice some log messages as following.

PS: I am having Jitsi -meet and Videobridge on different server hardware.

Log from prosody.log.

Also, here is additional log from jvb.log on my Videobridge server.

Based on above log, any suspicious you could point out?

Thanks and regards,

Could you check the prosody status?

systemctl status prosody

What are the resources? RAM, CPU etc

Seyma · December 9, 2020, 9:46am

Dear Emrah,
Here is the output of prosody as well as resources status.

Any idea you might suggest based on above screenshot?

Thanks and regards,
Seyma

emrah · December 9, 2020, 11:32am

There are some problems on your prosody. Did you update the system?

Seyma · December 9, 2020, 12:18pm

Dear Emrah,

We did not update our system. Could you please advise what should we do to get it fixed?

Regards,
Seyma

Is TCP/5222 open on JMS?
Does JVB have static IP or dynamic?
If you set NAT_HARVESTER for JVB, could you check the current IP and the HARVESTER IP are matched

Seyma · December 10, 2020, 1:39am

Dear Emrah,

Based on netstat result, port TCP/5222 is open on Jitsi Meet Server.
JVB has public static IP assigned.
We do not have NAT since JVB is statically assigned with a public IP.

Any more suggestion I should check further?

Regards,
Seyma

emrah · December 10, 2020, 6:11am

Does the following command print an XML output?
Run it on JVB

curl http://meet.yourdomain.com:5222/

Seyma · December 10, 2020, 6:20am

Yes, it prints the XML output as following.

| <?xml version='1.0'?><stream:stream id=’’ xmlns:stream=‘http://etherx.jabber.org/streams’ version=‘1.0’ xmlns=‘jabber:client’>stream:error</stream:error></stream:stream>

Restarting the JMS server and then JVB servers may work if the services were started in the wrong order during the tests
