HTML/CSS: Originally had TTF issues when loading site on IE but since fixing, seeing these errors

Question

I have fonts installed like this on my site:

    @font-face {
      font-family: 'Avenir-Book';
      font-style: normal;
      font-weight: 400;
      src:  url('/fonts/Avenir-Book.eot?#iefix') format('embedded-opentype'),
            url('/fonts/Avenir-Book.ttf') format('truetype');
     }

However, when I try to run it from Internet Explorer, the site won't open and these errorrs appear in console:

CSS3111: @font-face encountered unknown error.
Avenir-Book.eot
CSS3114: @font-face failed OpenType embedding permission check. Permission must be Installable.
Avenir-Book.ttf

Not exactly sure what I am doing wrong as I thought the eot file resolves IE issues.

@Robbeoli this was the question I originally referenced in my solution. I am using the solution with EOT's as directed there — herkypam, May 14 '19 at 23:44
@Robbeoli really? I said "I am using the solution with EOT's as directed there" — herkypam, May 14 '19 at 23:54
Easy there, herky. That solution is not the accepted solution. By the vote count it seems like it should work, though. What I asked you, is if you tried the solution actually accepted by the OP from the question. — Robbeoli, May 14 '19 at 23:57

CSS3114 can be resolved by adding the following fixes under <system.webServer> in web.config:

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

CSS3111 could be caused by Windows 10 feature called Entrusted Font Blocking. You can disable it using group policy or using registry editor. For further information and detailed steps, please check this article.
