Java org.openqa.selenium.remote.UnreachableBrowserException:无法启动新会话

我正在尝试运行一个selenium脚本，以便在这里提到的浏览器堆栈中实现自动化

当我在eclipse中运行这个脚本时，我发现了下面的错误

问题是由于在代理后运行脚本。由于被阻止访问URL

hub.browserstack.com，我出现了此错误。

您能发布更多关于如何初始化webdriver/webbrowser的代码吗？@spcial iI已经添加了代码。请check@spcial我想在browserstack提供的远程浏览器中运行脚本。所以我想我不能像你说的那样设定路径，因为你完全正确，所以我删除了我的“答案”。实际上我自己也没有用过browserstack。但我认为您是对的，这是一个代理设置失败，因为

HttpHostConnectException

。。我也坐在代理后面，无法ping hub.browserstack.com。。但是从我的vserver（不在代理后面）执行ping可以很好地工作。您可以打开控制台并尝试“ping hub.browserstack.com”。。如果你没有收到ping回复，我认为代理很可能会阻止它：）@spcial我从cmd收到ping，请求超时。所以我认为这是一个代理问题。你是如何解决这个问题的？当我尝试访问提到的URL时，我得到了{“value”：{“message”：“Invalid Command”}响应
