title: Require ip 127.0.0.1 works sometimes and sometimes' it won't
body: <p>I have a very simple <code>.htaccess</code> file:</p>
  
  <pre><code>&lt;RequireAll&gt;
      Require all granted
  
      # require localhost
      Require ip 127.0.0.1
  &lt;/RequireAll&gt;
  </code></pre>
  
  <p>and it works... sometimes!</p>
  
  <p>Sometimes, it will throw me a 403, and the <code>error.log</code> explains:</p>
  
  <blockquote>
    <p>[client ::1:65443] AH01630: client denied by server configuration</p>
  </blockquote>
  
  <p>Why won't it match that local client to the <code>Require ip 127.0.0.1</code> rule?</p>
