title: How to fix "Could not get any response" in Postman?
body: <p>Postman for Linux
  Version 6.7.1
  Deepin x64</p>
  <p>I'm trying to test a get method on postman to test my code, but I always get this error message.</p>
  <blockquote>
  <p>Could not get any response.</p>
  <p>There was an error connecting to localhost:3001/blocks.</p>
  <p>Why this might have happened:</p>
  <p>The server couldn't send a response:</p>
  <p>Ensure that the backend is working properly</p>
  <p>Self-signed SSL certificates are being blocked:</p>
  <p>Fix this by turning off 'SSL certificate verification' in Settings &gt; General</p>
  <p>Proxy configured incorrectly</p>
  <p>Ensure that proxy is configured correctly in Settings &gt; Proxy</p>
  <p>Request timeout:</p>
  <p>Change request timeout in Settings &gt; General</p>
