WebDriverException:转发新会话时出错转发连接到my\u ip的请求时出错:5555[/my\u ip]失败:连接超时

我在AWS windows上安装并启动了selenium节点。我在AWS Linux上安装了Jenkins、git、Seleniuim hub。当我在Jenkins上构建应用程序时,selenium hub正在尝试使用连接到AWS windows的selenium节点 专用IP地址 . 我得到以下例外:

org.openqa.selenium.WebDriverException: 
Error forwarding the new session Error forwarding the request Connect to windows_private_ip:5555 [/windows_private_ip] failed: Connection timed out (Connection timed out)

Caused by: org.openqa.grid.common.exception.GridException: Error forwarding the new session Error forwarding the request Connect to windows_private_ip:5555 [/windows_private_ip] failed: Connection timed out (Connection timed out)

网格节点命令:

C:\Users\Administrator>java -Dwebdriver.chrome.driver=./drivers/windows-driver/chromedriver.exe -jar C:\\Users\\Administrator\\Desktop\\selenium-server-standalone-3.0.1.jar -role node -hub http://ip_address:4444/grid/register

我的代码是:

if (browser.equalsIgnoreCase("FF")) {
            System.setProperty("webdriver.gecko.driver", "drivers/windows-driver/geckodriver.exe");
            DesiredCapabilities cap = DesiredCapabilities.firefox();
            // Set the platform where we want to run our test- we can use
            // MAC and Linux and other platforms as well
            cap.setPlatform(Platform.ANY);
            cap.setCapability("gecko", true);
            // Here you can use hub address, hub will take the
            // responsibility to execute the test on respective node
            URL url = new URL("http://hub_public_ip:4444/wd/hub");
            // Create driver with hub address and capability
            gbb = PageFactory.initElements(new RemoteWebDriver(url, cap), GuruBase.class);
        } else if (browser.equalsIgnoreCase("IE")) {
            System.setProperty("webdriver.ie.driver", "drivers/windows-driver/IEDriverServer.exe");
            gbb = PageFactory.initElements(new InternetExplorerDriver(), GuruBase.class);

        } else if (browser.equalsIgnoreCase("GC")) {
            System.setProperty("webdriver.chrome.driver", "drivers/windows-driver/chromedriver.exe");
            ChromeOptions cho = new ChromeOptions();
            cho.addArguments("disabled-extensions");
            cho.addArguments("--start-maximized");
            gbb = PageFactory.initElements(new ChromeDriver(cho), GuruBase.class);
        }

        else if (browser.equalsIgnoreCase("html")) {
            gbb = PageFactory.initElements(new HtmlUnitDriver(true), GuruBase.class);
        }

我在Jenkins上运行selenium中心。
