title: Grails - localhost:8080 refused to connect
body: <p>I am trying to run my first Grails app and I am getting a error when I try to go to localhost:8080. It just refuses to connect.</p>
  
  <p>I followed Dan Vega's instructions in his video <a href="https://www.youtube.com/watch?v=PlMyRGIJNa0" rel="nofollow noreferrer">https://www.youtube.com/watch?v=PlMyRGIJNa0</a> carefully but I cannot get my app to run.</p>
  
  <p>I have tried to change the host but couldn't get to the right place to do so. Any help would be much appreciated.</p>
