I can see live app on secured port 443 red5pro

Question

I prepared server ubuntu like from docs. I created SSL cert to my domin and i have open required ports. I installed red5pro in to /usr/local/red5pro/ and server fine. When i will go to http://example.com:5080/ i can see home page red5pro and is ok. But when i click on broadcast i have a info: No suitable Publisher found. WebRTC & Flash not supported. Ok, maybe because is http not https. I decided create test index page in to /var/www/test/index.html and i have basic configuration like:

var config = {
          protocol: 'wss',
          host: 'example.com',
          port: 443,
          app: 'live',
          streamName: 'abccaccaa',
          rtcConfiguration: {
            iceServers: [{urls: 'stun:stun2.l.google.com:19302'}],
            iceCandidatePoolSize: 2,
            bundlePolicy: 'max-bundle'
          } // See https://developer.mozilla.org/en-US/docs/Web/API/RTCPeerConnection/RTCPeerConnection#RTCConfiguration_dictionary
        };

And now when i try broadcast have an info: WebSocket connection to 'wss://example.com/live/?id=abccaccaa' failed: Error during WebSocket handshake: Unexpected response code: 404

Looks like have no example.com/live and cant figure out what is wrong :( since 2 days. Maybe someone could give me an advice ? Or alternative on other application than red5pro
