thank you in advance

It looks like you forgot (as I did) to make an entry in your DNS system that points to the IP of the Jitsi server. You should go to the system where your DNS records are managed, add an A record with the value ‘’ that points to the ip of the sever where you’ve installed Jitsi.

thank you very much for your reply,
but I installed Jisti behind an ADSL connexion and my IP address is private

The Jisti application is installed on this IP address ie

For DNS I dont know who manage it in our zone.

Please I don’t if I understand very well. but I still need your help because I am very newbie in jisti.

thank you Arnold, thank you for all

If you’re using jitsi ONLY inside your network I higly suggest to simply share and install the certificate in every computer that need to connect as a trusted certificate, doing this you’re safer from outside.

Otherwise you should check your router configuration if it support a dynamic dns provider and setup if (hoping in the list there’s a free one) and adding the port forwarding in the router and many other stuff that could expose your pc or network to outside attacks, I sincerely not advise doing so if it’s your pc and not a dedicated machine.

Thank you in advance,
I installed Jitsi in a machine inside my lan (with a private addresses like 192.168.1.* ). For the visioconference I want to be accessed from outside.
My default gateway is a Dlink box( which has a dhcp server, and other options.
But I didn’t understand if the task that you said must be done to this box or I have to contact my ISP.

Thank you

Dear all,
I think that my problem hasn’t solution. I navigated throw Internet and I met always with the same problem: nobody can solve this issue: no certificate. So I am planing to uninstall jitsi and replace it with another solution like google hangout or webex of cisco etc…
So I have 2 questions:

  1. How to uninstall jisti properly and avoid thus to have conflict between the dependencies of Jisti with other application in the future
  2. Which one of these solutions is most suitable and usefull to my situation(making some courses remotely for twenty participants or twenty five simultaneouosly)

Thank you in advance.

Depends on the router, you shoud expose your PC to external networks and this lead a lot to your network security. I’d advise to not do it. Anyway it’s done as I wrote in the previous posts. You should obviously set a static IP for your PC.

Simply run next command:

apt-get purge jigasi jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet-turnserver jitsi-meet-web jicofo jitsi-videobridge2
