internet explorer font face ssl

I faced the same behaviour using spring-boot:
the solution I found was to

– Hide Pragma and Cache-Control returned headers to the browser:

Spring-boot is responding with specific Cache-Control and Pragma HTTP headers.

Cache-Control :"no-cache, no-store, max-age=0, must-revalidate"
Pragma :"no-cache"

Internet explorer (IE11 in my case) is not able to load fonts with those headers.
I believe its a bug and we have to cope with it.

Using nginx to proxy our spring-boot application,
I could overcome the problem ,
hiding that headers to the browser by using the following nginx configuration commands:

server {
        listen 443;
        server_name server.dns.name;
        ssl on;
        ssl_certificate /etc/nginx/ssl/server.dns.name.pem;
        ssl_certificate_key /etc/nginx/ssl/server.dns.name.key;

        location / {
            include  /etc/nginx/mime.types;
            rewrite ^/(.*) /$1 break;
            proxy_pass  http://127.0.0.1:8080;
            proxy_read_timeout 90;

            #IE specific tweak for fonts not to be ignored:
            proxy_hide_header Cache-Control;
            proxy_hide_header Pragma; 
            #END IE specific tweak for fonts not to be ignored
        }
}
