Insomnia rest client error
<p>When I do a POST request I am getting this error.
Error: connect ECONNREFUSED 127.0.0.1:3000.
On the contrary, when I use postman it works.</p>

<p>This is the url:
<a href="http://localhost:3000/users/sign_in" rel="nofollow">http://localhost:3000/users/sign_in</a></p>

<p>And this is my configuration:</p>

<p>JSON tab:</p>

<pre><code>{"user": {"email": "user@nivelr.com", "password": "clave12345"}}
</code></pre>

<p>Headers:</p>

<ul>
<li>Accept        application/json</li>
<li>Content-Type  application/json</li>
</ul>
