Socket.IO connection error

Question

I've an application in node.js with socket.io. Everything was running completely fine, but suddenly the browser started to send this error.

failed: Error in connection establishment:net::ERR_TUNNEL_CONNECTION_FAILED

I didn't make any code change.

The protocol used by socket is ws:// and when I try to use this url in browser

'ws://highgarden-nodejs-91180.sae1.nitrousbox.com/socket.io/?EIO=3&transport=websocket&sid=T9Unec8KbWw-GAL8AAAF'

Chrome returns this error:

Failed to load resource: net::ERR_DISALLOWED_URL_SCHEME

This is a part of the socket setup code:

server.js:

    var app = express();
    var server = http.createServer(app);
    var io = require('socket.io').listen(server);
    var port = process.env.PORT || 3000
*------------------------------------------*

    // routes ===
    var routes = require('./config/routes.js');
    var sock = {}
    routes(app, passport, sock); 
    io.sockets.on('connection', sock.update);

    // launch ===
    server.listen(port);

Thanks advance.

Answer 1

Hi the exception ERR_TUNNEL_CONNECTION_FAILED happens when a tunnel connection through the proxy could not be established. And the ERR_DISALLOWED_URL_SCHEME happens when the scheme of the URL is disallowed.

May you need use it behind the proxy!
