I'm working on a Headless website based on Drupal 8, I installed CORS module and in CORS domain set `*|*` , client side can read my views rest endpoint but when client side try to load a file url returned by views rest result, I faced with CORS error ,

`XMLHttpRequest cannot load http://domain.com/sites/default/files/home-slider-slide3-audio/2016-11/tr_SaidNursi.mp3. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://xx.domain.com' is therefore not allowed access.`

how can I resolve this problem?

my webserver is NGINX
