When Joining conference client cannot connect together only displaying black screen (own server jitsi meet)

I have a problem with this config.

what I did.

  1. install quick install of jitsi-meet
  2. follow [How to] How to build Jitsi Meet from source: A developer's guide this guide line on how to move it to my own jitsi meet pulled from git ( newest version )

nginx is running, jitsi meet can be accessed but no view. i guess it is not because of the planB version since it is the latest jitsi meet, i dont know how to check my version of jitsi meet i pulled. but since i dont give any version i guess it pulled the latest.

this is my dpkg -l , ignore the jitsi-meet part as it was the quick install version

ii jitsi-meet 2.0.8319-1 all WebRTC JavaScript video conferences
ii jitsi-meet-prosody 1.0.6991-1 all Prosody configuration for Jitsi Meet
ii jitsi-meet-turnserver 1.0.6991-1 all Configures coturn to be used with Jitsi Meet
ii jitsi-meet-web 1.0.6991-1 all WebRTC JavaScript video conferences
ii jitsi-meet-web-config 1.0.6991-1 all Configuration for web serving of Jitsi Meet
ii jitsi-videobridge2 2.2-79-gf6426ea0-1 all WebRTC compatible Selective Forwarding Unit (SFU)
ii lua-basexx 0.4.1-jitsi1 all baseXX encoding/decoding library for Lua
ii lua-cjson:amd64 amd64 JSON parser/encoder for Lua

does anyone have opinion on this?

Participants can see the other participants event there is no video?

Do you have any error in the browser console?

no, participant cannot see others even when they join, its like they are not even in the same conference. no error in the console i guess other than SSL certificate since i did not add the self generated cert on client

Check nginx logs and prosody ligs for errors.

yes nothing showed up on nginx server just client disconnected error. but I finally fixed the problem. in the tutorial it does not say to change all usr/share/jitsi meet. i changed the alias directory on nginx config and it work now, thank you guys for the help!
