Hi,
Copy the below code and paste it into web.config file then it will work fine
<system.webserver>
<staticcontent>
<remove fileextension=".eot" />
<mimemap fileextension=".eot" mimetype="application/vnd.ms-fontobject" />
<mimemap fileextension=".woff" mimetype="application/font-woff" />
</staticcontent>
</system.webserver>
