Good day. Seems like websocket connection is not established between application and WCS server. This is probably networking issue. Please check the following:

1. Are WS port 8080/tcp and WSS port 8443/tcp available on server?
2. Can you publish/play from browser on the same device to the same server in the same network? If not, please try to change network
3. Is the problem reproducing in Player example? If not, modify example code minimally to reproduce the issue, then create a topic on the support forum https://forum.flashphoner.com/ and send the modified code using "Report" button. Please use the button only in your personal topic, or we cannot respond to it.

1. Yes. wss port 8443 available on server.
2. Working fine on same device on browser on the each network.
3. Github player demo not connecting with wss port 8443. Getting failed each time every network.
