Hello Wandenberg,

Yes, the back-end(s3 bucket) is sending Content-Type header for each request and what I heard from the developers that the header is must for the site to work properly.

The issue started when I got the request of enabling content-type header of all the json files to application/json. As the default content-type in NGINX is application/octet-stream, the JSON files are served as application/octet-stream. The jquery uses content-type header to identify the JSOn files and due to the application/octet-stream content type it is not able to identify the JSOn files.

I tried many options but each time one of the features(html files got downloaded, CSS not loaded, CSS problem in internet explorer) got impacted.

I will try adding all the mime types to the map directive and will let you know the result.

Here is my nginx.conf and vhost file for your reference
