title: Error "Gradle sync failed: Connection refused: connect"
body: <p>So I just installed Android Studio again after a long time and it asked me to configure the proxy, so I did. I tested the connection and it worked.</p>
  <p>Then it asked me to configure the proxy settings for Gradle and I used the same configurations.</p>
  <p>Now, when loading the latest Vuforia Sample project, I get an error:</p>
  <blockquote>
  <p>Gradle sync failed: Connection refused: connect</p>
  </blockquote>
  <p>I've looked everywhere on the web, but I can't find a solution. It can't be the proxy settings; I've configured Gradle just like the IDE.</p>
