curl: (7) Failed to connect to localhost port 3000: Connection refused
<p>I typed this into terminal </p>

<pre><code>$ curl -X POST http://localhost:3000/voice
</code></pre>

<p>and I got this error </p>

<pre><code>curl: (7) Failed to connect to localhost port 3000: Connection refused
</code></pre>
