title: Selenium unable to create new session
body: <p>This is coming about because I have a failing Behat test on a search field - the field is added via javascript so I assumed something was wrong with (with my setup of) Selenium.</p>
  
  <p>I found that if I visit <a href="http://localhost:4444/wd/hub" rel="nofollow noreferrer">http://localhost:4444/wd/hub</a> and click "Create Session", select <em>any</em> of the browsers (android, iphone, firefox, chrome, internet explorer, opera) I get the error message: <code>Unable to create new session</code>.</p>
  
  <p>I'm not sure if the two are related (failing <code>@javacript</code> tests and unable to create a session).</p>
  
  <p>I am starting Selenium with <code>java -jar /usr/local/bin/selenium-server-standalone-3.5.0.jar -port 4444</code> on osX Sierra 10.12.5.</p>
  
  <p>My current configuration in behat.yml is</p>
  
  <pre><code>javascript_session: selenium2
    goutte: ~
    selenium2:
      wd_host: 'http://localhost:4444/wd/hub'
  </code></pre>
  
  <p>Although I wouldn't expect that to affect the ability to create a session from <code>/wd/hub</code>.</p>
