for this, but when I run my app behind a load balancer, I get this error on the client: WebSocket connection to 'wss://fakedomain.com/socket.io/?EIO=3&transport=websocket&sid=QH8VmXbiEcp3ZyiLAAAD' failed: Error during WebSocket handshake: Unexpected response code: 400 I understand the error, since it's trying

to talk to the load balancer and now the EC2 instance (I'm not great with AWS so feel free to offer help on this one!) but what I don't understand is how to make the error not show up! I'd love to fix the root cause but I'm guessing it involves a separate dedicated socket.io server to handle all the real time stuff which I don't have time for at the moment, but could someone please run me through supressing error during websocket handshake: unexpected response code: 404 this error? I'm assuming it's falling back to polling, which seems to work just fine (I have the socket connection connected and it fires) but I don't want to launch with a red error in my console. Thanks in advance for any advice you might have! framerate commented Oct 30, 2014 Also, I've installed via bower if it matters: "socket.io-client": "~1.1.0", ggrav commented Oct 30, 2014 Do you have sticky connection on your server? yads commented Oct 30, 2014 I assume you're not using Elastic Beanstalk (the instructions there would be much easier). Go to EC2->Network & Security->Load Balancers Select your load balancer and go to Listeners. Ensure that both the Load Balancer protocol and the Instance Protocol are set to TCP for port 80 and SSL for port 443 rather than HTTP and HTTPS. 👍 4 🎉 1 framerate commented Oct 30, 2014 Oh man. This is solid advice I haven't seen elsewhere. I'll try in the AM and report back.

Here is the exact error: WebSocket connection to 'ws://example.com/sockjs/477/z3heiyow/websocket' failed: Error during WebSocket handshake: Unexpected response code: 400 It deploys perfectly fine, it doesn't throw out any errors either.

The weird thing is that it almost works i.e. you can see the other players move around, except it's very laggy and slow. The same app worked fine on Scalingo hosting, so it must be an OpenShift thing. This is my client side code for initiating socket.io: script var socket = io(); And server: var express = require('express'); var app = express(); var http = require('http').Server(app); var io = require('socket.io')(http); app.get('/', function(req, res){ res.sendFile('index.html'); }); this.ipaddress = process.env.OPENSHIFT_NODEJS_IP; this.port = process.env.OPENSHIFT_NODEJS_PORT || 8000; http.listen( port, ipaddress, function(){ console.log('listening on:' + port); }); javascript node.js websocket socket.io openshift share|improve this question asked Mar 3 at 18:02 abun 316 Duplicate, maybe: stackoverflow.com/questions/19948974/… (your app still works, but poorly, because socket.io falls back to XHR long-polling which is vastly less performant than WebSockets) –apsillers Mar 3 at 18:11 Thank you, I got it working. The performance still leaves something to be desired, there's a pretty noticeable delay (~90ms) betwe
