python用selenium打开网址显示whitelabel error page

Question

我在写一个关于智慧树刷课的脚本

打开课程视频所在的链接会出现whitelabel error page

但是打开登陆的url不会出错

如何解决这个问题？

我本来想通过在登陆以后click（）课程达到同样的目的

但是程序报错找不到标签

请问这是什么原因？我是新手，直接copy了课程title的xpath

#         self.accout=account#账户
#         self.pdw=pdw#密码
#         self.max_lesson=max_lesson#最大课程数

# # #自动解决弹出问题
