I do not know what is going on but in the browser console I can see 3 errors related to font-awesome

I was having the exact same issue on a "cPanel shared host server" that only allows for Apache2 webserver. Since wildcards (*) of the value of 'Access-Control-Allow-Origin' are not permitted by the shared host security settings (because: bandwidth & resource thieves) I had to figure out a different way to make it work.
This question asked by the OP infers nginx, but the accepted & most upvoted answers seem to be for IIS. There might be people (like me) who stumble upon this question looking for apache2 solutions related to CORS "permissions" in Apache, so here was the magic bullet for me to solve this issue. I added the following at the tippy-top of my root directory of a WP site in the .htaccess file:
SetEnvIf Origin "http(s)?://(.+\.)?(othersite\.com|mywebsite\.com)(:\d{1,5})?$" CORS=$0
Header set Access-Control-Allow-Origin "%{CORS}e" env=CORS
Header merge Vary "Origin"
I wish I could take credit for this fantastic hunk of RegEX magic, but I explain how I derived this solution in this post comment to a similar question here: Access-Control-Allow-Origin wildcard subdomains, ports and protocols
** Obvious NOTE: You need to change the domain name to match your own. You can remove the (|) RegEx OR and just use a single domain name in which ALL subdomains AND the root level domain name are accepted by the RegEx
