I am getting the all too common connection refused error on my selenium webdriver. The same code was executing a few weeks ago.
I have been reading in circles through existing posts and have tried updating geckodriver and FireFox to no avail. I can run the same code on another computer running the same versions of the driver, browser and libraries etc. How can I find the cause specific to this machine? the error is below.
Debug 1 Debug 2 Debug 3

And I get this running even the following basic code.
enter code here
package seleniumPrograms;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
public class Gecko_Driver {
public static void main(String[] args) {
System.out.println("Debug 1");
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
System.out.println("Debug 2");
capabilities.setCapability("marionette", true);
System.out.println("Debug 3");
WebDriver driver = new FirefoxDriver(capabilities);
System.out.println("Debug 4");
driver.get("http://www.google.com");
driver.manage().window().maximize();
driver.quit();
}
}
Example with chrome.
@Test
public void testGoogleSearch() throws InterruptedException {
// Optional, if not specified, WebDriver will search your path for chromedriver.
System.setProperty("webdriver.chrome.driver", "C:\\chromedriver_win32\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://www.google.com/xhtml");
Thread.sleep(5000); // Let the user actually see something!
WebElement searchBox = driver.findElement(By.name("q"));
searchBox.sendKeys("ChromeDriver");
searchBox.submit();
Thread.sleep(5000); // Let the user actually see something!
driver.quit();
}

Our security dept introduced a policy which blocked access to the execution of the geckodriver.exe. This was identified by attempting to run from cmd. Not sure why I didn't get the meaningful error in the IDE (blocked by group policy) for gecko, I did get this error for chrome and IE. In order to use the driver it needed to be saved in Program files though this may be specific to my situation. If you get this error for Geckodriver i would suggest trying to execute it from cmd to see if there is a policy issue.
