React App running fine on localhost but not able to fetch static files like main.chunk.js, bundle.js and 0.chunk.js etc

The Application is running fine on localhost but when the react app development server is hosted on production with a public Ip and accessed using that public Ip the page is not able to fetch static files like favicon, main.chunk.js, bundle.js, and 0.chunk.js, etc. I am proxying react app development server with Nginx using a route /rx on this production server. I had begun this project using create-react-app. It was working fine till now but suddenly this problem has popped up and even reverting the commits to earlier stable ones is not helping.

My index.js looks like this

This is how my package.json looks like

This is how my app.js looks

Here are the error Screen Shots when accessed over public ip

However everything is working fine when same code is accessed over localhost as seen follows.
