More details about server requirements for production

While trying to build out the client node machine and the "hypernova" server I had issues hitting the server from an external host. Example can be found here: https://github.com/pixeloven/typescript-react-component-library

In this example I am unable to connect the client to the server when they are running on different hosts. the express client seems to be ok being accessed "0.0.0.0:8080/health" but I can't hit the server can not ad 8081.

node-server    | { listen: [ 9001, '0.0.0.0' ] }
node-server    | 2018-09-27T22:48:47.342Z - info: Worker #7 is now connected to 0.0.0.0:9001
node-client    | {}
node-client    | Preparing MyComponent { name: 'Stranger' }
node-client    | Requesting MyComponent { name: 'Stranger' }
node-client    | Error: connect ECONNREFUSED 0.0.0.0:9001

The above example is showing different ports but the idea is the same. the server is refusing connections.
