title: httpd not starting due to SSLProtocol: Illegal protocol 'TLSv1.1' error
body: <p>I have a subscription plan with MediaTemple, and the server was automatically upgraded / updated. When I woke up this morning I found that the sites on the server and the emailing do not work at all.</p>
  
  <p>I logged in to Plesk (admin panel for MediaTemple DV server), and found an error message: "New configuration files for the Apache web server were not created due to the errors in configuration templates: Syntax error on line 230 of /etc/httpd/conf.d/ssl.conf: SSLProtocol: Illegal protocol 'TLSv1.1' ."</p>
  
  <p>I tried to rebuild the corrupted files, then all the configuration files (rebuild automatically), then restart the server - nothing helped that I could do.</p>
  
  <p>Here are the (not commented lines) from the ssl.conf:</p>
  
  <pre><code>&lt;IfModule mod_ssl.c&gt;
  SSLCipherSuite HIGH:!aNULL:!MD5
  &lt;/IfModule&gt;
  &lt;IfModule mod_ssl.c&gt;
  SSLHonorCipherOrder on
  &lt;/IfModule&gt;
  &lt;IfModule mod_ssl.c&gt;
  SSLProtocol +TLSv1 +TLSv1.1 +TLSv1.2
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>Everything is in its default state, as I have never touched apache files (I do not know these).</p>
  
  <p>If I try to rebuild all files, then I get this error message:
  Unable to configure the web server: Execution failed. Command: httpdmng Arguments: Array ( [0] => --reconfigure-all ) Details: Execution failed. Command: httpdmng Arguments: Array ( [0] => --reconfigure-server [1] => -no-restart ) Details: [2016-12-08 04:28:35] ERR [util_exec] proc_close() failed ['/usr/local/psa/admin/bin/apache-config' '-t'] with exit code [1] [2016-12-08 04:28:37] ERR [util_exec] proc_close() failed ['/usr/local/psa/admin/bin/apache-config' '-t'] with exit code [1] [2016-12-08 04:28:37] ERR [panel] Apache config (14811893120.14461900) generation failed: Template_Exception: Syntax error on line 230 of /etc/httpd/conf.d/ssl.conf: SSLProtocol: Illegal protocol 'TLSv1.1' file: /usr/local/psa/admin/plib/Template/Writer/Webserver/Abstract.php line: 75 code: 0 Syntax error on line 230 of /etc/httpd/conf.d/ssl.conf: SSLProtocol: Illegal protocol 'TLSv1.1'</p>
  
  <p>The server is a CentOS 6.4 (Final), and the admin is Plesk Onyx - Version 17.0.17 Update #9, last updated on Dec 7, 2016 04:02 PM.</p>
  
  <p>I opened a support ticket with MediaTemple for the problem, but the estimated response time is 20 hours - which is a "bit" too long for websites to be down.</p>
