@font-face failed OpenType embedding permission check. Permission must be Installable

This exception occurs in here. You can reproduce it in IE11. So far I have not found the cause of the issue. Any ideas why this is being caused?

The web site is running on Azure Websites platform and is using ASP.NET MVC 5.

Solution

  • Fixed by adding 

    <staticContent>
  <mimeMap fileExtension=".woff" mimeType="application/octet-stream" />
</staticContent>

    under

     <system.webServer>

    in web.config.

    Edit:

    to prevent any problems with consequent releases I recommend doing this:

    <staticContent>
      <remove fileExtension=".woff" />
      <mimeMap fileExtension=".woff" mimeType="application/octet-stream" />
</staticContent>
