title: ngrok not connecting to local server
body: <p>So, I am running ngrok (current version) on my Mac OSx. But I am getting the following error:</p>
  
  <pre><code>Failed to complete tunnel connection
  The connection to http://35504712.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:3746.
  
  Make sure that a web service is running on localhost:3746 and that it is a valid address.
  
  The error encountered was: dial tcp xx.xx.xx.xx:3746: getsockopt: connection refused
  </code></pre>
  
  <p>I know my server is running properly, as I can actually click the link to my localserver in the error message and get a response from my server.</p>
  
  <p>Any ideas on how to diagnose?</p>
