title: Positive SSL trusted in Chrome for desktop but not for Android
body: <p>I have just bought a Positive SSL Certificate but it does not work in Chrome for Android, I get <code>NET::ERR_CERT_AUTHORITY_INVALID</code>. However, everything is OK with the Chrome for desktop.</p>
  
  <p>This is how I configure my <strong>apache2</strong> server:</p>
  
  <pre><code># File /etc/apache2/sites-available/000-default.conf
  &lt;VirtualHost *:80&gt;
     ServerName example.com
     Redirect permanent / https://example.com/
  &lt;/VirtualHost&gt;
  
  &lt;VirtualHost *:443&gt;
  
          ServerAdmin webmaster@localhost
          DocumentRoot /var/www/html
  
          ServerName example.com
          SSLEngine on
          SSLCertificateFile  /root/ssl/certificate/example.com.crt
          SSLCertificateKeyFile  /root/ssl/example.com.key
          SSLCertificateChainFile /root/ssl/certificate/intermediates.crt
          # In version 2.4.8 or newer
          #SSLCACertificateFile /root/ssl/certificate/intermediates.crt
  
          ErrorLog ${APACHE_LOG_DIR}/error.log
          CustomLog ${APACHE_LOG_DIR}/access.log combined
  &lt;/VirtualHost&gt;
  </code></pre>
  
  <p>And here it's how I created <code>intermediates.crt</code>:</p>
  
  <pre><code>cat COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt &gt; intermediates.crt
  </code></pre>
  
  <p>What am I missing?</p>
