Answer 1

We were having the same issues on our jenkins slaves (linux machine) and tried all the options above.

The only thing helped is setting the argument

chrome_options.add_argument('--headless')

But when we investigated further, noticed that XVFB screen doesn't started property and thats causing this error. After we fix XVFB screen, it resolved the issue.
