Ember Cli Deploy via Lighting Strategy

We have deployed our Ember App using Lightning Deploy Strategy which involves:

• EC2 instance
• Nginx (HTTP Server)
• Redis, configured on same instance (to serve index.html)
• compiled js and assets from AWS S3

When, upon hitting the instance, the index.html gets served from Redis, and subsequently on clicking any route in the App, the App routes get served.

But, when we manually enter any correct route in URL for the Ember App, Nginx throws an error saying route not found. Anything wrong that we are doing here?
