title: curl: (7) couldn't connect to host What is wrong in my settings?
body: <p>When I run command:</p>
  
  <pre><code>$ curl http://localhost:9201
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>curl: (7) couldn't connect to host
  </code></pre>
  
  <p>Next when I run command <code>curl</code> with verbose flag i.e.:</p>
  
  <pre><code>$ curl -v http://localhost:9201
  </code></pre>
  
  <p>It ends up with error:</p>
  
  <pre><code>* About to connect() to localhost port 9201 (#0)
  *   Trying ::1... Connection refused
  *   Trying 127.0.0.1... Connection refused
  * couldn't connect to host
  * Closing connection #0
  curl: (7) couldn't connect to host
  </code></pre>
  
  <p>I really cannot understand why this error happens. What is wrong in my settings? How can I fix this?</p>
