You can look error in screenshot.

Maybe check prosody logs.

Hos did you install? What OS? This is strange, the connection between prosody and the webserver is bosh over http and there should not be any ssl … did you modify in any way the default installation?

I didn’t modify in any way the default installation.
I have followed this instruction : https://jitsi.org/downloads/ubuntu-debian-installations-instructions/ for installation.
My server is on Ubuntu.

And you did just sudo apt-get -y install jitsi-meet. You should follow https://jitsi.org/qi.

Also I did follow this https://jitsi.org/qi for installation but i am getting same error.
What should i do?
