The video and audio cann't show in jitsi-meet

Can’t transfer audio and video.
The colibri-ws is working, but will be fail finally.

Is everything hosted on the same sever?
Share your nginx config.

Is everything hosted on the same sever?
Yes, jvb jicofo and prosody, but i deploy the frontend package on another server, and i transfered all interfaces to the backend server(http-bind and colibri-ws).

The [] is my backend server path, which hosts jvb jicofo and prosody.
Now, jitsi-meet works fine through [], but fails in my frontend server https domain.

This is the frontend server Nginx config

    map $http_upgrade $connection_upgrade {
         default upgrade;
         ''      close;
    set $prefix "";

      alias /webapp/jitsi-meet/;
    location ~ ^/jitsi-meet/(libs|css|static|images|fonts|lang|sounds|connection_optimization|.well-known)/(.*)$ {
      add_header 'Access-Control-Allow-Origin' '*';
      alias /webapp/jitsi-meet/$1/$2;
