Font Awesome not showing

Hello!

I’ve just installed Hueman theme on my subdomain and I saw that the Font Awesome is not loading, but it is showing on my main domain.

cosplay.hallowedgaming.com is my subdomain
https://www.hallowedgaming.com is my domain.

I have also tried to add this into .htaccess but didn’t work:

<FilesMatch ".(ttf|otf|eot|woff)$">
  <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
  </IfModule>
</FilesMatch>

Note that the public_html/subdomain doesn’t have the same name as cosplay.hallowedgaming.com.

How can I fix Font Awesome?

Thank you for this beautiful theme! <3
