python-3.x - Selenium 的连接问题 - Python

Question

我在这里使用 Selenium 来自动执行某些操作，出于安全考虑，程序会在登录页面等待用户填写表格并登录以继续，并且由于某种未知原因，如果我等待太长时间无法登录出现以下错误：

这些异常会导致另一个异常，但我认为这是相关代码。

我这样设置驱动程序：

    self.ie = webdriver.Edge(application_path + '\\MicrosoftWebDriver.exe')
    self.driver = EventFiringWebDriver(self.ie, MyListener())

MyListener对象仅进行一些隐式等待，也没有任何相关性。

错误是葡萄牙语，但它说“通常每个套接字地址只允许使用一次（协议/网络地址/端口）”

如果您花费的时间不够长，该程序运行得很好，但是该错误有时会在执行它的随机点发生。

提前致谢！

我把整个回溯放在它有帮助的情况下，如果它也有帮助，这是我等待用户登录的循环，这是我可以保证等待太久导致异常的地方：

def login(self):    
    url = 'https://somepage.com'

    self.driver.get(url)

    while self.driver.execute_script('return document.title') != "Page Title":
        pass
