Python 3.x Selenium代理服务器参数-未知错误：net:：ERR\u隧道\u连接\u失败

希望你很好

我在尝试设置chrome webdriver时遇到了一个小问题。我正在尝试更改webdriver的参数以旋转用户代理和IP（我使用它是为了刮取，不想使用相同的IP和UA获得spot）

当我通过UA论证时，一切都很顺利。但当我添加IP参数时，由于一些我无法确定的原因，它系统性地失败了。我总是收到以下错误

WebDriverException: unknown error: net::ERR_TUNNEL_CONNECTION_FAILED
  (Session info: chrome=86.0.4240.198)```

行为总是一样的，驱动程序根据请求打开网页，然后页面加载一段时间，直到指示站点不可访问为止

下面是使用的代码。你知道它是从哪里来的吗？（不幸的是，我在这方面找不到类似的帖子）
