Major issues configuring AWS Elastic Beanstalk Nginx to work with socket.io connections

I am running a socket.io node.js app on AWS Elastic Beanstalk. I have not included express.js.

Obviously Nginx proxy on Elastic Beanstalk doesn't pass TCP connections through without manual configuration.

I am trying to connect to it via my Android client or browser.

I have tried literally every solution on the internet, but I either get 502 Bad gateway, or timeout errors.

Should I change the AWS Elastic Beanstalk load balancer to accept TCP not HTTP ?

My node.js app is listening on port 3000 (hardcoded). Works great on localhost.

var server = require('http').createServer(handleRequest); var io = require('socket.io')(server); function handleRequest(request, response) { response.end('It Works!! Path Hit: ' + request.url); } io.on('connection', function (socket) { console.log('a user connected'); socket.on('disconnect', function () { console.log('user disconnected'); }); socket.on('chat message', function (msg) { console.log('message received on server: ' + msg); io.emit('chat message', msg); }); }); server.listen(3000, function () { console.log("Server listening on port:", 3000); //Callback triggered when server is successfully listening. Hurray! }); 

Here is my package.json

{ "name": "qurba-messaging-backend", "version": "0.0.1", "scripts": { "start": "node main.js" }, "dependencies": { "socket.io": "^1.4.6" } } 

Here is my nginx configurations https://gist.github.com/RobinBuschmann/c42a413ecedee463e5bd8e613ddd8d04
