title: Trouble Getting Chrome Through Selenium Hub
body: <p>I am using Selenium Webdriver, 2.25  I have a local hub set up with this json setting for chrome and firefox:</p>
  
  <pre><code>[
      {
          "browserName": "firefox",
          "maxInstances": 5,
          "seleniumProtocol": "WebDriver"
      },
      {
          "browserName": "chrome",
          "maxInstances": 5,
          "seleniumProtocol": "WebDriver"
      }
  ],
  </code></pre>
  
  <p>I can start a webdriver firefox session like this:</p>
  
  <pre><code>capability = getattr(webdriver.DesiredCapabilities, "FIREFOX")
  dd=webdriver.Remote('http://localhost:4444/wd/hub', capability)
  </code></pre>
  
  <p>which works fine
  but if I try to start a Chrome session like this:</p>
  
  <pre><code>capability = getattr(webdriver.DesiredCapabilities, "CHROME")
  dd=webdriver.Remote('http://localhost:4444/wd/hub', capability)
  </code></pre>
  
  <p>I get this error:</p>
  
  <blockquote>
    <p>Traceback (most recent call last):
      File "", line 1, in 
      File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 62, in <strong>init</strong>
        self.start_session(desired_capabilities, browser_profile)
      File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 104, in start_session
        'desiredCapabilities': desired_capabilities,
      File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 155, in execute
        self.error_handler.check_response(response)
      File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 147, in check_response
        raise exception_class(message, screen, stacktrace)
    selenium.common.exceptions.WebDriverException: Message: None ; Stacktrace: Method innerGet threw an error in None</p>
  </blockquote>
  
  <p>But I can start a direct connection to Chrome like this:</p>
  
  <pre><code>dd=webdriver.Chrome()
  </code></pre>
  
  <p>Without any problem.</p>
  
  <p>What can I do to get to Chrome through my Selenium Hub?</p>
