[SOLVED] Users are kicked out with message "you have been disconnected, rejoin" on Docker-jitis-meet with NGINX proxy

Hi Guys,

first of all thanks to all for their awesome work.


  • Debian GNU/Linux 9.12 (stretch) with public IP
  • NGINX as proxy (takes care of ssl)

I can access the ui and I can create a new channel.

  • With Firefox: I keep getting disconnected with the rejoin message.

  • With Chromium: I get disonnected when someone else attempts to connect (everyone has the same experience, tested on Fedora, Adnroid client and MAC Chrome)

  • subdomain.mydomain.tld/http-bind?room=tester gives the following output.
    It works! Now point your BOSH client to this URL to connect to Prosody.
    For more information see Prosody: Setting up BOSH.

  • Port 10000/udp has been tested with nc in the following way:
    On the server side LISTEN to 10000 with: : nc -ulk -p 10000 On the client side : nc -vu serverIP ServerPort
    Everything I’ve typed in at the client sied will be transferred to the server and is shown in the cli

  • Other Ports are working as I can connect to the UI.

  • Config directories are created and are writable

My configs and at the end the error log of firefox.

# MUC name for the Jibri pool

# MUC connection timeout

# When jibri gets a request to start a service for a room, the room
# jid will look like: roomName@optional.prefixes.subdomain.xmpp_domain
# We'll build the url for the call by transforming that into:
# https://xmpp_domain/subdomain/roomName
# So if there are any prefixes in the jid (like jitsi meet, which
# has its participants join a muc at conference.xmpp_domain) then
# list that prefix here so it can be stripped out to generate
# the call url correctly

# Directory for logs inside Jibri container

# Disable HTTPS: handle TLS connections outside of this setup

# Redirect HTTP traffic to HTTPS
# Necessary for Let's Encrypt, relies on standard HTTPS port (443)

# Container restart policy
# Defaults to unless-stopped

NGINX config (for Information, ssl certificates are manged central and are not configured in every single server configuration, as I can connect to the UI with a valid certificate everything should be okay from this side):

If there is any further information you need just let me know.

Thanks in advance and stay save

So, figured it out on my own.

The important part is the message:
Error: "Strophe: request id 10.1 error 413 happened"
in the console log. I just not realized 413 is a http erro code. Later on I just come around the network tab in the dev tools and there it was again.
Little investigation brings up this lines in the nginx root conf:
client_body_buffer_size 1K;
client_max_body_size 1k;
Change it to a higher value for the jitsi domain fixed the problem.

Could you please tell me what values did you set for client_body_buffer_size and client_max_body_size ? is there a maximum value for each parameter ?

I’ve set it to zero which corresponds to no limit.
I will track the size of the post request in the browser to the bosh url subdomain.mydomain.tld/http-bind?room=tester soon so I can adjust the size and I will inform you here.
