AWS Elastic Beanstalk Node.js Socket.io 400 (Bad Request)

I have attempted to resolve this and looked around but I still cannot figure out how to resolve this matter.

I set my AWS Elastic Beanstalk instance to run with 2 server instances and now I'm getting the following:

WebSocket connection to 'ws://.com/socket.io/?EIO=3&transport=websocket&sid=ygwpRoYU4e_WYr7QAADQ' failed: Error during WebSocket handshake: Unexpected response code: 400 socket.io.js:2919 POST http://.com/socket.io/?EIO=3&transport=polling&t=1422547055741-674&sid=ygwpRoYU4e_WYr7QAADQ 400 (Bad Request) socket.io.js:2919 GET http://.com/socket.io/?EIO=3&transport=polling&t=1422547056603-676&sid=hDkZib1rxiodV10EAADR 400 (Bad Request) socket.io.js:3509 WebSocket connection to 'ws://.com/socket.io/?EIO=3&transport=websocket&sid=hDkZib1rxiodV10EAADR' failed: WebSocket is closed before the connection is established.

Does anyone have any idea on how to resolve this?

Your help is really appreciated.
