[Solved] Reconnecting after 30 seconds when user joins in the created room

Hello, I want a solution to a problem; whenever someone joins the already created room and after 30 seconds of joining they both automatically disconnects from room and a reconnecting dialog always appears.
I have installed jitsi-meet in Ubuntu 20.04 (GCP) as it serving live.netpractice.app (35.202.136.190) by following quick install blog https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-quickstart. I have completed advance configurations like:

org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=<IP GOT BY IFCONFIG>
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=35.202.136.190

And commented the existing org.ice4j.ice.harvest.STUN_MAPPING_HARVESTER_ADDRESSES, and also allowed the given tcp/udp ports by using ufw commands.

jvb.log:

This is a configuration issue of some sort:
This server does not serve auth.live.netpractice.app

Can you “attach” (not paste) your /etc/prosody/conf.avail/...cfg.lua config file?

Is there anything interesting in your /var/log/prosody/prosody.log around this same time, or on prosody startup?

Also, what does this command show you?
sudo netstat -anlp | grep 5347
My guess is nothing.

Can you please help me out on this? I didn’t find prosody.log in the given given location. I’ve just followed quick installation steps.

When I execute this sudo netstat -anlp | grep 5347
it is showing as below:

tcp        0      0 127.0.0.1:5347          0.0.0.0:*               LISTEN      600/lua5.2

Please find the attachment live.netpractice.app.cfg.lua (3.7 KB) /etc/prosody/conf.avail/live.netpractice.app.cfg.lua.

this is mysterious. If you have not restarted the instance, what gives
ls -lart /proc/600/fd

(if you have restarted the instance, the pid of prosody could have changed, so get the new one by running again sudo netstat -anlp | grep 5347)

and you can attach a file by clicking on the upload button (the icon is an arrow pointing upside) - I don’t think it’s criminal to paste the file if it’s done correctly as you did in your first post BTW :slight_smile:

When I ran ls -lart /proc/600/fd

Thanks, and I have attached /etc/prosody/conf.avail/live.netpractice.app.cfg.lua in my previous reply.

so prosody does open the file, so why can’t you find it ?

Sorry, I was searching in wrong directory. /var/log/prosody/prosody.log (14.7 KB)

test port 10000 connectivity

(server)
sudo systemctl stop jitsi-videobridge2
nc -l 10000 -u
(workstation)
echo "123" | nc -u (your public address) 10000

Nothing is happening, I stopped jitsi-videobridge2, and ran nc -l 10000 -u in server.

after I ran in my system echo "123" | nc -u live.netpractice.app 10000
both screens are in waiting state.

if nothing appears on your Jitsi server console, maybe you could go to the hoster management console and enable a redirection for the port 10000 /UDP or disable the firewall or whatever is blocking the connection.

I’ve enabled as given in docs, via ufw. still it is not working.
can you please guide me for further fixing, as you mentioned hoster management console.

I can’t help you about Google cloud console as I don’t use it.

Restart this three services.

sudo systemctl restart prosody.service
sudo systemctl restart jicofo.service
sudo systemctl restart jitsi-videobridge2.service

Thank you! We enabled it from GCP! Now it is working…
