Hi There @senvas
Thanks for writing in! Upon testing, your issue seems to be related to your server policy. I see the following on your console log.
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource
Could you please try adding the following into your .htaccess file and see if that helps. You can see the detailed guide from here (https://theme.co/apex/forum/t/troubleshooting-font-awesome/200).
Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
Let us know how it goes.
