(unknown error: DevToolsActivePort file doesn't exist)

I managed to fix it with --headless argument on ChromeOptions but i believe it’s causing the authentication process to fail at https://m.facebook.com/.

Any other way to fix it?

Awesome, thank you @vtroussel ! This worked for me too. I’ve used this code to make it headless by default, and it seems to run faster. Appreciate you sharing this, let me know if any other ideas for improvements or feel free to do a pull request.

@jcontini I modified the “ENTER” input as a button click. Also augmented the time.sleep but I don’t think that is where the problem was coming from.

confirm_id = browser.find_element_by_name("login")
confirm_id.click()
time.sleep(4)
