The HTTP referer header is missing and therefore it is not possible to verify the origin requesting our fonts. Typically this could be caused by inclusion of the "" in the "" tag of your pages, or by the configuration of your server, proxy or firewall. Please make sure your website includes correct HTTP referer header in all requests to our service.
