Adding Webfont Files as MIME types to the Web Server

I added some font awesome icons to my page. And I am getting an error that says that fontawesome-webfont.woff2, woff, and ttf are not found 404.
When I added BS4 -> minty - It added the font awesome link automatically that is located in boostrap/4/css/

If I overwrite this link and put the CDN for fontawesome - it gets overwritten with the link that is there now, however, it is producing that 404 error. Any thoughts on why this is happening?
