This fixes the React Router issues where you allow nginx to route traffic coming on different endpoints, directly to you React Application.

The answer is found in this thread React-router and nginx

What I had to do was modify default configuration file in /etc/nginx/sites-available/default to:

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri /index.html;
    }
