Websockets with socket.io on AWS Elastic Beanstalk

I'm trying to setup a websocket-server with socket.io on AWS Elastic Beanstalk. Got the initial request to /socket.io/1/?t=xxxx up and running but the websocket handshake fails with this error:

WebSocket connection to 'ws://xxxxxx.elasticbeanstalk.com/socket.io/1/websocket/a4DTCN2BeJZuiSaphVyz' failed: Unexpected response code: 502

From googling and looking at the error 502 (Bad Gateway) it seems to have something to do with the nginx-proxy. So how do I configure the nginx to work with websockets?

Can't find anything in AWS documentation about setting up for websockets.

you could try to go through the trouble of configuring nginx, but if you are only using websockets, it would be easier to turn off all proxys and directly connect.

this is under your app environment in the elastic beanstalk dashboard. There's a drop down button on the right marked "Actions". Select "Edit/Load Configuration"
