我的seleniumwebdriver上出现了太常见的连接拒绝错误。几周前执行了相同的代码。

我一直在阅读现有帖子中的内容，并尝试将geckodriver和FireFox更新无济于事。我可以在另一台运行相同版本的驱动程序，浏览器和库等的计算机上运行相同的代码。如何找到特定于该计算机的原因？错误如下。

而且，即使是以下基本代码，我也可以运行它。

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();
        }
 }

铬示例。

@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();
        }
