title: Mixed SSL Content Preventing Joomla Installation/Operation with Nginx
body: <p>I must be missing something obvious but I cannot install Joomla 3.6.5 on a site with SSL already in place due to mixed content.</p>
  
  <p>I get the following in my browser console:</p>
  
  <blockquote>
    <p>Mixed Content: The page at '<a href="https://example.com/joomla/installation/index.php" rel="nofollow noreferrer">https://example.com/joomla/installation/index.php</a>' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint '<a href="http://example.com/joomla/installation/index.php" rel="nofollow noreferrer">http://example.com/joomla/installation/index.php</a>'. This request has been blocked; the content must be served over HTTPS.</p>
    
    <p>XMLHttpRequest cannot load <a href="http://example.com/joomla/installation/index.php" rel="nofollow noreferrer">http://example.com/joomla/installation/index.php</a>. Failed to start loading.</p>
  </blockquote>
  
  <p>Web searches for "Joomla Installation on SSL" and similar all generate pages that assume a search for how to introduce SSL <strong><code>AFTER</code></strong> installation.</p>
  
  <p>Appreciate ideas on how to avoid having to switch off SSL just to install Joomla.</p>
  
  <h1>EDIT</h1>
  
  <p>Turns out this is an issue related to SSL Termination using a reverse proxy such as Nginx and that this does not affect Apache given the way Joomla v3.6 is written to operate.</p>
