title: React, localhost refused to connect
body: <p>I am trying to create a basic application that I able to serve as a movie database. Im following a tutorial on YouTube (<a href="https://www.youtube.com/watch?v=jc9_Bqzy2YQ&amp;t=243s" rel="nofollow noreferrer">link</a>) (I have reached 5:22 in the video)</p>
  <p>Im stuck banging my head against the wall because I cannot get the app to run in a chrome browser. At the current stage all I should see is a blank white screen.</p>
  <p>Instead when I run it I see chrome saying that &quot;this site can't be reached&quot; and &quot;local host refused to connect&quot;</p>
  <p>I have tried EVERY possible solution I could find on the internet. These are a notable few:</p>
  <ol>
  <li>Disabling computer firewall</li>
  <li>changing localhost:8080 to localhost:3000</li>
  </ol>
  <p>I am running MacOS and the latest version of react and visual studio code.
  I've attached a few images for your reference.</p>
