Getting Unknown Error: Chrome Failed to Start: Exited Abnormally. (Unknown Error: Devtoolsactiveport File Doesn't Exist)

WebDriverException: unknown error: DevToolsActivePort file doesn't exist while trying to initiate Chrome Browser

Update:

I am able to get through the issue and now I am able to access the chrome with desired url.

Results of trying the provided solutions:

I tried all the settings as provided above but I was unable to resolve the issue

Explanation regarding the issue:

As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.

Steps taken to solve the issue

1. I have killed all the chrome processes and chrome driver processes.

2. Added the below code to invoke the chrome

   System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");    
   ChromeOptions options = new ChromeOptions();
   options.setExperimentalOption("useAutomationExtension", false);
   WebDriver driver = new ChromeDriver(options);
   driver.get(url);
   

Using the above steps I was able to resolve the issue.

Thanks for your answers.

selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist with chromium browser and Selenium Python

I solved the problem by reinstalling chromium through apt sudo apt install chromium-browser (before that it was installed through snap). My working code looks like this

options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--no-sandbox")
if headless:
options.add_argument('--headless')
options.binary_location = "/usr/bin/chromium-browser"
self.driver = webdriver.Chrome(options=options)

Selenium: WebDriverException:Chrome failed to start: crashed as google-chrome is no longer running so ChromeDriver is assuming that Chrome has crashed

Try to download HERE and use this latest chrome driver version:

• https://sites.google.com/chromium.org/driver/

Try this:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
d = webdriver.Chrome('/home/<user>/chromedriver',chrome_options=chrome_options)
d.get('https://www.google.nl/')

WebDriverException: Chrome failed to start: exited abnormally (unknown error: DevToolsActivePort file doesn't exist)

This is for java, but I think it should work for you to:

It says that is is a permission issue. Try running your program as root.

WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally using Selenium ChromeDriver and Chrome through WebDriverManager

You need to take care of a couple of things here as follows:

• You need webdriver.Chrome() only once. If you don't need the arguments through Options() keep:

  driver = webdriver.Chrome(service=service)
  

  and remove:

  driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options)
  

  or vice versa.

• If you are executing as a non-root using add_argument('--headless') generally you may not even require the following arguments:

  • add_argument('--no-sandbox')
  • add_argument('--disable-dev-shm-usage')

• You can try to initiate the new Browsing Context i.e. google-chrome-headless using:

  driver = webdriver.Chrome(service=ChromeDriverManager().install(), options=chrome_options)
  

• Your effective code block will be:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  from selenium.webdriver.chrome.service import Service
  from webdriver_manager.chrome import ChromeDriverManager
  
  chrome_options = Options()
  chrome_options.add_argument('--headless')
  # optional
  chrome_options.add_argument('--no-sandbox')
  # optional
  chrome_options.add_argument('--disable-dev-shm-usage')
  
  driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options)
  driver.get('http://192.168.15.1/me_configuracao_avancada.asp')
  

Note: Ensure that you have installed webdriver-manager and Chrome browser within your system before you kickoff your test execution.
