Node.JS & Mongo expert to work out why my redundantly deployed AWS App cant use a single Mongo DB

Hi All,

I am using Openhab cloud, a node.js app that uses redis & mongo. I have deployed 2 of these instances onto Ubuntu Linux in AWS EC2.

The App is here: [login to view URL]

Primary/Secondary. They sit behind an AWS ELB load balancer.

There is also a third server, an Ubuntu Mongo DB server.

I can successfully use 1 of the Node.JS App servers to the Mongo Server, but when I use 2 (ie I add both servers into the ELB group) I get errors (504 Gateway) and other issues.

I need someone to solve the issue and make my application highly available behind the ELB in AWS and using the external Mongo Server

Bids that will be ignored:

- Hiring Managers

- People with fake profile photos that are clearly not them

- People who reply with website/html development experience

Thank you

Skills: Linux, node.js, MongoDB, Amazon Web Services
