连接局域网中的另一台电脑，做selenium webdriver 远程测试，之前一直是好的，后来过几天再运行发现报以上错误，网上搜了下，问题解决，原理暂时没时间研究.

原来代码为：

WebDriver webDriver;

webDriver = new RemoteWebDriver(new URL("http://192.168.0.30:4444/wd/hub"), DesiredCapabilities.internetExplorer());

改为：

WebDriver webDriver;

DesiredCapabilities ieCapabilities = DesiredCapabilities.internetExplorer();

      ieCapabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS, true);

 webDriver = new RemoteWebDriver(new URL("http://192.168.0.30:4444/wd/hub"), ieCapabilities);
