title: Issues sending requests using fetch
body: <p>I am using FETCH to make GET requests. I am also using NGROK for HTTP tunneling. My problem is here when I use <code>var url = 'http://localhost:9090/test-message'</code>, I get a response but when I use <code>
  https://c2f2493e.ngrok.io/test-message</code> I don't get a response. I don't know what the problem might be here.</p>
  
  <p>Here is the full code:</p>
  
  <pre><code>fetch(url).then(function(response) {
      console.log(response)
  })
  </code></pre>
