Node.js + Apache-https：// localhost：3000 / socket.io / ERR_CONNECTION_REFUSED

Question

I am implementing a simple game in Node.js. I have a client.js for my client side code, and a server.js running on a remote server, which both use sockets to communicate on port 3000

I am also running Apache on port 80 , and using ProxyPass in my apache configuration file, to route the url mywebsite.io/agario to my nodejs server.

<Location /agario>
     ProxyPass http://localhost:3000/
     ProxyPassReverse http://localhost:3000/
</Location>

I am also using cloudflare to route my webserver 167.179.xx.xx through the url https://agario.mywebsite.io for SSL so that I can use HTTPS.

The problem

When I try to connect to my website https://agario.mywebsite.io/agario I am receiving the following error:

socket.io-1.4.5.js:1 GET https://localhost:3000/socket.io/?EIO=3&transport=polling&t=MakAMgZ net::ERR_CONNECTION_REFUSED

I am unclear why my client code is trying to connect to localhost, when I have specified in the code to connect to the remote server. Potentially I am just confused on how to run the node.js server as this is my first taste of Node.js and sockets.

client.js

...
var socket;
socket = io.connect('https://agario.mywebsite.io/agario');
...

server.js

var app = express();
var server = app.listen(3000, listen);

// This call back just tells us that the server has started
function listen() {
  var host = server.address().address;
  var port = server.address().port;
  console.log('Example app listening at http://' + host + ':' + port);
}

app.use(express.static('public'));
var io = require('socket.io')(server);

io.sockets.on('connection',
  function(socket) {
    console.log("We have a new client: " + socket.id);

...

});

If I have missed out any vital information please let me know and I will update my question, thank you.

Answer 1

You server is listening on port 3000 and you're trying to connect with it via 443, you should try something like this

socket.connect('https://ip:3000');

However, if you're sure that ur client is using the same port as the server or u have a port forwarding then try to use netcat just to make sure the the problem is with your script not the network config :

nc -zv -w1 ip port
