"Unfortunately something went wrong" error


I set up Jitsi server on VPS (not behind NAT). It works properly from my home network, but any session crashes only from my office network.

OS: Ubuntu 18.04

Chromium console:

[modules/RTC/BridgeChannel.js] <l._send>:  Bridge Channel send: no opened channel.
[conference.js] <ee._onConferenceFailed>:  CONFERENCE FAILED: conference.iceFailed
[modules/RTC/BridgeChannel.js] <RTCDataChannel.e.onerror>:  Channel error: undefined

Can anyone help me?

I have the same issue as you.

I’m very disappointed with Jitsi.

I had the same issue and no solution yet. But, I tried to connect to internet through third party VPN then the jitsi meeting works!
I do not know what is the link between the vpn and this issue!
Maybe this info get some idea.

Does a conference with 3 or more participants work while connecting from the home network? Not P2P…

Is port 10000 UDP open?

Yes. A conference works fine not only with 2 participants (P2P) but also with more than 2 from my home network.

In the case of my office network, only one person conference works fine. But when the second person joins the meeting, it crashes in about 10 seconds.

Thank you for your information about your workaround. I’ll try it.

Thank you for your comment. It’s reassuring to know that it’s not just a problem for my office network. For me, Jitsi meeting is wonderful software and I’d like to find some kind of solution.

@yasser It works perfectly through VPN! Thank you for your advice.

But it’s a just workaround…? :thinking:

Do you use your own SSL?

I followed the self-hosting guide and used Let’s Encrypt SSL Certificate.

Hi, I used my own SSL certificate and I having the same problema?, there is any issue with that?

Hi oshie,

You can try my method.
Step 1: sudo apt purge jigasi jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet-turnserver jitsi-meet-web jicofo jitsi-videobridge2.

Step 2: hostnamectl set-hostname yourdomain (example: abc.net.us)

Step 3:
sudo ufw allow OpenSSH
sudo ufw allow http
sudo ufw allow https
sudo ufw allow 10000:20000/udp
sudo ufw enable

Step 4:
Sudo apt system
Sudo apt upgrade –y && sudo shutdown –r now

Step 5
sudo apt install -y openjdk-8-jre-headless

echo “JAVA_HOME=$(readlink -f /usr/bin/java | sed “s:bin/java::”)” | sudo tee -a /etc/profile source /etc/profile

Step 6:
sudo apt install -y nginx
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

Step 7
wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add –

sudo sh -c “echo ‘deb https://download.jitsi.org stable/’ > /etc/apt/sources.list.d/jitsi-stable.list”

sudo apt update –y

sudo apt install -y jitsi-meet

input your domainname if jitsi ask you. If not, it is the same the first installation.

Choice “I want to use my certificate”

Step 7: Update SSL key and SSL crt to folder and verify SSL install success.

That’s all.

Try and give me feedback.


I tried as you said and this happens, after even two clients on chrome browser it disconnects.

I realise the problem. It was the server that was not opening the port 10000/udp. After the server opened the port, it worked.

Besides how can i change the

* <meta itemprop="description" content="Join a WebRTC video conference powered by the Jitsi Videobridge" />

* <meta itemprop="image" content="images/jitsilogo.png?v=1" />

i got the same issue and i found my jitsi video bridge service stopped.

but it is stopping did not find the solution

Is it mean my solution is work?
