Rails Passenger Glyphicon CORS Cloudfront NGINX Issue

Question

So I am aware that stackoverflow is wrought with these questions about CORS Nginx, Cloudfront and Heroku but for some reason I can't get it to work. I have been following this question's answer:

How do I configure `Access-Control-Allow-Origin` with rails, nginx and passenger?

However I can't seem to figure out where to put the custom code block:

config/nginx.conf.erb

Next, edit the configuration file config/nginx.conf.erb by finding a block that looks as follows:

location @static_asset {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
    add_header ETag "";
} ...and add the two Access-Control lines:

to

>     location @static_asset {
>         gzip_static on;
>         expires max;
>         add_header Cache-Control public;
>         add_header ETag "";
>         add_header Access-Control-Allow-Origin *;
>         add_header Access-Control-Request-Method *;
>     } That's it. This will work in production, but not in development, due to config.assets differences between the two.

in my Nginx configuration. I am using Phusion Passenger 5.0.23. The Nginx config doesnt have a location @static_asset block in the one that I pulled from passenger. It does have a section for custom configurations but that hasnt worked for me. My glyphicons continue to show up as boxes How do I get it to work? I have also tried this Phusion Passenger + Heroku + Cloudfront: CORS Configuration
