How to properly serve content through Nginx?

Question

Nginx

Tell me what's wrong? I can’t give HLS content, it works on the local, but not on my site, it gives an error like this.

XMLHttpRequest cannot load http://domen/hls/2x2/live.m3u8. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://****.info' is therefore not allowed access.

What to register in Nginx? to give header

Answer 1

http://domen/hls/2x2/live.m3u8
https://developer.chrome.com/extensions/xhr

Answer 2

Cross-Origin Resource Sharing
