I am new to node js development and i am using webrtc. My app is working correctly on localhost (on my pc) but on heroku server it is giving me this error:

"WebSocket connection to 'wss://https//webrtc-filetransfer.herokuapp.com/' failed: Error in connection establishment: net::ERR_NAME_NOT_RESOLVED WrappedWebSocket @ VM72:35 (anonymous) @ main1.js:20".

server side web socket code

var express = require('express');       
var bodyparser  = require('body-parser');         
var app = express();         
app.listen(process.env.PORT || 3000);              

app.use(express.static('client'));          
app.use(bodyparser.json());    
var SERVER_PORT = 8087 ;           
var WebSocketServer = require('ws').Server , wss = new WebSocketServer({port :8087});      

console.log("server_started");

Client Side Code is 

var ws = new WebSocket('wss:/https://webrtc-filetransfer.herokuapp.com/');         

       ws.onopen = function()    
       {

          // Web Socket is connected, send data using send()
          var data={
            mid:"login",
            uid: myId

          };
               ws.send(JSON.stringify(data));      

            };

Replace...

wss://https//webrtc-filetransfer.herokuapp.com/

...with:

wss://webrtc-filetransfer.herokuapp.com/

Specifying wss automatically tells a WebSocket client library to use https to connect to a WebSocket server. You don't need to further specify https in the URI

  • I am Having error : Error during WebSocket handshake: Unexpected response code: 503" again . – Gautam Mishra Feb 26 '17 at 12:12
  • @GautamMishra 503 generally means service is unavailable. Check the server logs for more detail. – Nehal J Wani Feb 26 '17 at 12:21
