You might want to add the following lines in your Web.config if you get 404: not found.

<system.webServer>
    <staticContent>
        <remove fileExtension=".vtt" /> <!--REMOVES SERVER .vtt extention if it exists-->
        <mimeMap fileExtension=".vtt" mimeType="text/vtt" /> <!--ads it again (needed when debuging)-->
    </staticContent>
</system.webServer></configuration>

Hopes this helps others. .vtt is not supported from scratch, and thus chrome (among others) blocks the content because of security reasons.
