Jitsi randomly getting down

i dont know if this is the right place to post this issue but hope that you can help me.

When two participants join meeting jitsi go down, not responding at all, after some times when i try to open my jitsi it shows me the attached picture.

im unable to find any helpful logs
i have checked jvb log and jicofo logs and after around 30 minute everything going back to normal

but i found this log in jvb

anyone can help or atleast someone tell em what should i trace?

Can it be resource issues on the server? What is the available RAM for the deployment?
The 404 and everything are failing to reach the webserver …

Thanks for replying

As not me who did the setup for the server
the current server ram is 8GB
and this server is only for jitsi meet how can i know the available ram for jitsi ?
and its failing on two users only

btw jitsi down when two opening video

Should be enough for normal operation.

Try checking the nginx process when you experience the problem, do you see any logs that may indicate why web resources cannot be reached?

Thank you for the reply
i found this log in niginx/error.log

Please be noted the server has 4 core vCPU is that a problem ?
And also be noted im testing with a phone and laptop in same meeting

So for some reason those files are missing … And for some reason prosody is not responding to the request, have you monitored the CPU usage of the server, are there spikes up to 100% and staying like that?

Cpu usage does not exceed 6 % at all
Memory available 5 GB as i monitored it when i let the problem happened

Meet going down only if both opened thier cameras during 15 seconds otherwise the meeting continue if they speak without open the cameras

I don’t understand how this is possible … so both participants in the call, bot or one of them turn on their camera and they both start seeing the page with 404?

Sorry for the confusion.
Nobody see 404. They will be disconnected during 15 seconds if they opened their camera.

After disconnecting jitsi go down, then my server will not be responding for a while, not even 404 page
after some times around 15 minute it starts showing 404 for each one who is trying to enter to my server
After 30 minute jitsi will work as expected

That’s odd … what is the client logs (the js console logs from the browser)? What errors do you see there?

Connection timeout

I can provide you with a link to my meeting to know exactly what is happening
Note that both participant have same creditnal

Have you tried with different credentials for the participants ?

To be honest no but i guess will be the same behavior.
May this cause a problem?

Maybe … I don’t know.
Not sure why your connection will timeout when you turn on video … and how that can affect the server and make it unreachable …
Can it be your local bandwidth is not enough and when you turn on the video and your internet or computer dies … and loses connection. I’m guessing here without seeing any logs…

If you can help me which logs you need this will be perfect

As a start the client logs. The javascript console logs from developer menu you can open the console. Save the logs when you reproduce the issue before the reload (I’m not even sure you see the reload page?).

Sounds clear enough thank you

Hello damencho

i just knew how to reproduce the issue

the issue is happening on specific routers
and the jitsi is not going down since i changed my ISP immediately and opened jitsi and jitsi got opened but the router which got the problem wont open it again for a while
here are the error logs that I took from the console of the browser

Note that i did setup a Coturn server with it in different server
