title: exception with a null response was thrown sending an HTTP request to the remote WebDriver server
body: <p>During Automation testing with selenium (C# Chrome WebDriver), I keep on getting the following error:</p>
  
  <p><strong>OpenQA.Selenium.WebDriverException : A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL <a href="http://localhost:62856/session/1414381932731debf24d49572cafd7b6/url" rel="nofollow noreferrer">http://localhost:62856/session/1414381932731debf24d49572cafd7b6/url</a>. The status of the exception was ConnectFailure, and the message was: Unable to connect to the remote server  ----> System.Net.WebException : Unable to connect to the remote server  ----> System.Net.Sockets.SocketException : No connection could be made because the target machine actively refused it [::1]:62856</strong></p>
  
  <p>I tried the following:
  1.  Adding the following arguments to ChromeDriver Options:</p>
  
  <pre><code>      options.AddArgument("no-sandbox");
        options.AddArgument("proxy-server='direct://'");
        options.AddArgument("proxy-bypass-list=*");
  </code></pre>
  
  <ol start="2">
  <li>Close all Chrome and ChromeDriver Processes prior to each run</li>
  <li>Removing Anti-Virus from my computer</li>
  </ol>
  
  <p>After all this, I am still left with this error.</p>
  
  <p>Thanks,</p>
