title: Google Chrome unable to navigate to specified URL when triggered from Selenium
body: <p>I have an automation framework developed around Selenium-WebDriver which launches Chrome and navigates to specified URL and performs specified automation.
  When I commissioned the framework to perform a long task and left it overnight to run (Run was not successful). The following day when I tried to re-run a new set of Tests, Selenium was able to fire Chrome but the Browser would not navigate to the specified URL. The following is the detailed stack trace.</p>
  
  <pre><code>Starting ChromeDriver (v2.7.236900) on port 60678

  <p>This is the second time I am facing the same issue.
  When I tried to google search the error I was able find <a href="https://vaadin.com/forum#!/thread/9195524" rel="noreferrer">this</a> particular forum.
  I tried to re-download Chrome_driver but it did not help. Restarting the system did not help either. I double checked the code and all the set-up but nothing was changed.
  Curiously I was able to stumble upon a curious solution.</p>
  
  <p>Solution - Re-installing Chrome Browser solved the issue. I was able to run the tests perfectly.</p>
  
  <p>I am curious to understand why this was and what might have caused chrome to behave so oddly.</p>
