Social Icons are not showing up – htaccess problem

Hi,
This is the error my site is throwing for the icons

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://secureservercdn.net/198.71.233.106/gz8.c17.myftpupload.com/wp-content/plugins/simple-social-icons/symbol-defs.svg. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing)

The response to the CORS request is missing the required Access-Control-Allow-Origin header, which is used to determine whether or not the resource can be accessed by content operating within the current origin.

I added in my htaccess file, below the wordpress ends

<IfModule mod_headers.c>
  <FilesMatch "\.(ttf|ttc|otf|eot|woff|woff2|font.css|css|svg)$">
    Header set Access-Control-Allow-Origin "*"
  </FilesMatch> 
</IfModule>

i did that, then I clean the cache on both ends (on WordPress and my side) and still the problem is there. Can you help me fix this issue, please?
