title: redis (error) ERR operation not permitted
body: <p>all of a sudden my redis database has started to give errors on some connections:</p>
  
  <pre><code>(error) ERR operation not permitted
  </code></pre>
  
  <p>I've restarted the redis service and am connecting to it with the client using the correct auth key, it connects everytime but only allows db operations through the client only some of the time.</p>
