title: CORS error suddenly shows – site was working fine until today
body: <p>Since this morning I get CORS errors in Chrome for my website trying to load font awesome fonts from a CDN. Both, production and development server are affected. I have not changed anything, the error came completely out of the blue:</p>
  
  <p><strong>Access to Font at '<a href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/fonts/fontawesome-webfont.woff2" rel="nofollow noreferrer">https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/fonts/fontawesome-webfont.woff2</a>' from origin '<a href="https://www.xxxx.com" rel="nofollow noreferrer">https://www.xxxx.com</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '<a href="https://www.xxxx.com" rel="nofollow noreferrer">https://www.xxxx.com</a>' is therefore not allowed access. The response had HTTP status code 502.</strong></p>
  
  <p>I have added </p>
  
  <p><code>Header set Access-Control-Allow-Origin "*"</code></p>
  
  <p>to the .htaccess of my server to no avail.</p>
  
  <p>What do I need to do to make this error go away? </p>
