Access-Control-Allow-Origin * (CSRF) header not being read?

Question

Nginx

I can't pull out Access-Control-Allow-Origin *
The server itself gives, but not a single browser sees this header.
Because of what I can not load fonts on the server.
site.conf

server {
    server_name realtime.mydomain.com;
    listen 80;
    add_header 'Access-Control-Allow-Origin' '*';
}

Answer 1

Browsers need permission to view. Add header
Access-Control-Allow-Credentials: true

Answer 2

Yes, that's nothing. It turned out that because of the domain. Was .xyz, did the same on .com and it worked.
