WebSocket connection failed. Error during WebSocket handshake - socketjs

Details:

I have been trying to configure my react project to work with hot loader so that I can actively develop without having to restart the server. I am getting a continuous error message each time websocket tries to connect:

WebSocket connection to 'ws://192.168.33.10/sockjs-node/301/eo4p2zps/websocket' failed: Error during WebSocket handshake: Unexpected response code: 404 . My gut tells me it might have to do with my VM (vagrant) which runs Ubuntu -v 14.04.3. In addition to the above error logged, I get:

http://192.168.33.10/sockjs-node/629/s0dz3nxv/xhr_streaming?t=1482558136743 404 (Not Found)

I've also taken the following boilerplate: https://github.com/jpsierens/webpack-react-redux in hopes to compare my current configuration but, both seem to be proper.

    // to see success build.
