WebDriverException: Unable to find open page error, unknown error when using ChromeDriver 80.0.3987.106 and Chrome 80.0.3987.122

Question

My local Windows 10 computer automatically updated the Chrome version to 80.0.3987.122 (official version) (64-bit)

I am using https://chromedriver.storage.googleapis.com/80.0.3987.106/chromedriver_win32.zip

But now I get this error:

Please protect the ports used by ChromeDriver and related test frameworks to prevent malicious code from accessing them.

How to solve this problem?

Answer 1

If you are using

--remote-debugging-port

Try to change the port number. The port number currently used may be occupied.

Answer 2

...means ChromeDriver cannot initialize/generate a new browsing context, i.e. Chrome Browser session.

It seems that the problem lies in the security feature of ChromeDriver, namely sandboxing. To bypass this feature, you can use the following parameters:

--no-sandbox

So your valid code block would be:

• Java

  options.addArguments("--no-sandbox"); # 绕过操作系统安全模型

• Python

  options.add_argument('--no-sandbox') # 绕过操作系统安全模型
