In my case, I could see this issue only when using Win 10 + IE 11. Even after ensuring correct IE settings (security zone and font download enabled), the font won't render. It seems that cache headers should not be set for fonts.

We are using Spring MVC and Tomcat. Adding following code in CORS filter solved problem for me.

        if (!request.getServletPath().endsWith(".woff")
                && !request.getServletPath().endsWith(".ttf")) {
            response.setHeader("Cache-Control", "no-cache");
            response.setHeader("Pragma", "no-cache");
            response.setDateHeader("Expires", -1);
        }
