title: How to use Forge Design Automation without ngrok?
body: <p>I am trying to go through the "Modify your Models" example from <a href="https://learnforge.autodesk.io/" rel="nofollow noreferrer">https://learnforge.autodesk.io/</a></p>
  
  <p>Unfortunately <em>ngrok</em> is not working in our corporate network. If I try to run any of the command below</p>
  
  <pre><code>ngrok http 3000 -host-header="localhost:3000"
  ngrok http 80
  </code></pre>
  
  <p>The only thing I get is:</p>
  
  <pre><code>listen tcp 127.0.0.1:4049: socket: An invalid argument was supplied.
  </code></pre>
  
  <p>and the tunneling is not working.</p>
  
  <p>Is there any other option available?</p>
