title: Redis::CommandError: ERR Client sent AUTH, but no password is set
body: <p>This has to be some wrong config</p>
  
  <p>I installed redis on localhost.</p>
  
  <p>When trying to connect to it through Rails console</p>
  
  <pre><code>Redis.new(:host =&gt; 'localhost', :port =&gt; 6379)
  </code></pre>
  
  <p>I can't send commands and I get </p>
  
  <pre><code>Redis::CommandError: ERR Client sent AUTH, but no password is set
  </code></pre>
  
  <p>I don't recall setting a password, nor do I know where to see if a password has been set</p>
  
  <p>if I use a different URL (like rediscloud or redistogo) I can send commands (setting the password accodingly)</p>
  
  <p>From what I understand the error says that I am sending a password, but redis doesn't have a password. But, as you can see, I am not setting any password..</p>
  
  <p>Is there a way to debug this?</p>
