title: Laravel Dusk error: Failed to connect to localhost port 9515: Connection refused
body: <p>As the title says, I've go a clean install of Laravel 5.4 and the latest Homestead (1.0.1). However, when I run a simple Dusk test case I get the following error: </p>
  
  <blockquote>
    <p>Failed to connect to localhost port 9515: Connection refused</p>
  </blockquote>
  
  <p>Anyone know how to deal with this? I tried changing the port to something else such as <code>8888</code> to no avail.</p>
  
  <p>EDIT:
  I've been able to dig a little deeper and found out that the <code>chromedriver</code> executable was not actually executable (<code>chmod</code>). Now that I've fixed that I get this error when I manually try to run it.</p>
