body: <p>I am trying to run a simple program using Selenium Grid(have no prior knowledge of selenium grid), and I am having error shown as below:</p>
  
  <p>Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

  String Node = "http://192.168.1.164:4444/wd/hub";
  DesiredCapabilities cap = DesiredCapabilities.chrome();
  cap.setBrowserName("firefox");
  //cap.setPlatform(Platform.WIN10);
  
  driver = new RemoteWebDriver(new URL(Node), cap);
  
  driver.navigate().to(URL);
  Thread.sleep(5000);
  driver.quit();
