“WebSocket connection to 'wss://localhost:9000/' failed: WebSocket opening handshake was canceled”

Application + Implementation overview In out application we need to performig video recording. We went ahead with MediaRecorder API hosted at https://developer.mozilla.org/en/docs/Web/API/MediaRecorder_API. We are getUserMedia API to access webCam and mic. We are using MediaRecorder API to record short blobs and sending it on application server hosting NodeJS WebSocket. ( Data transmission in short blobs to server is happening in every 2 second. On app server we keep on accumulating data and finally create a .webm media file. Issue: All this is working fine with HTTP protocol, but whenever we put application on SSL and starts erring with below description; Error Text: “WebSocket connection to 'wss://localhost:9000/' failed: WebSocket opening handshake was canceled” Error screenshot: Can any of you guide us with whats the issue specifically with HTTPS here.
