SessionNotCreatedException: Message: session not created from disconnected: unable to connect to renderer with ChromeDriver 2.45 Chrome v71

When I'm executing this code with Selenium using Python:

from selenium import webdriver
from selenium.webdriver.common.by import By
import time
driver = webdriver.Chrome(executable_path=r'/Users/qa/Documents/Python/chromedriver')

The error occurred:

   Traceback (most recent call last):

Can someone help me? Thanks.

I was facing the same issue with selenium. Adding this helped in my case.

options.add_argument('--disable-gpu')
options.add_argument('--no-sandbox')
options.add_argument('--disable-setuid-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument("--start-maximized")
options.add_argument("--window-size=1920,1080")

This worked for me on WINDOWS OS

from selenium import webdriver
import time
from bs4 import BeautifulSoup
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu')
driver = webdriver.Chrome(options=options)
driver.get(url)
time.sleep(3)
page = driver.page_source
driver.quit()
soup = BeautifulSoup(page, 'html.parser')

Hope you'd find this useful. I also used it more comprehensively here.

I am facing the same error and add the close code solve the problem, the code finnaly block look like this:

    @staticmethod
    def fetch_music_download_url(music_name: str):
        chrome_driver_service = Service(ChromeDriverManager(chrome_type=ChromeType.GOOGLE).install())
        chrome_options = Options()
        chrome_options.add_argument("--headless")
        chrome_options.add_argument("--no-sandbox")
        chrome_options.add_argument("--disable-gpu")
        chrome_options.add_argument("--remote-debugging-port=9230")
        driver = webdriver.Chrome(service=chrome_driver_service, options=chrome_options)
        try:
            driver.maximize_window()
            driver.get('http://example.cn/music/?page=audioPage&type=migu&name=' + music_name)
            driver.implicitly_wait(5)
            // do some logic
        except Exception as e:
            logger.error(e)
        finally:
            // add the close logic
            driver.stop_client()
            driver.close()
            driver.quit()
            chrome_driver_service.stop()

the key is you should close the chrome service after using it by add chrome_driver_service.stop().hope this code could help other people facing the same issue.

If you have options.add_argument("--remote-debugging-port=9222") change this to options.add_argument("--remote-debugging-port=9230")

or just simply Adding options.add_argument("--remote-debugging-port=9230") fixed in my case.

I had a similar error, first getting the error message:

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited normally. (unknown error: DevToolsActivePort file doesn't exist)

This was solved by adding options.add_argument("--remote-debugging-port=9230") to the ChromeOptions(). And the program runs once and I gained the same error message as above:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created from disconnected: unable to connect to renderer (Session info: headless chrome=89.0.4389.114)

The problem here was that the chrome process does not close properly in the program so the process is still active on the debugging-port. To solve this problem close the active port sudo kill -9 $(sudo lsof -t -i:9230) and simply add the following lines to the end of the code:

driver.stop_client()
driver.close()
driver.quit()

Since I didn't find this answer anywhere, I hope it helps someone.

I ran into this same issue on a Windows 10 machine. What I had to do to resolve the issue was to open the Task Manager and exit all Python.exe processes, along with all Chrome.exe processes. After doing this,

This error message...

selenium.common.exceptions.SessionNotCreatedException: Message: session not created
from disconnected: unable to connect to renderer

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

You need to consider a fact:

  • As you are using Mac OS X the Key executable_path must be supported with a Value as :

    '/Users/qa/Documents/Python/chromedriver'

  • So line will be:

    driver = webdriver.Chrome(executable_path='/Users/qa/Documents/Python/chromedriver')

Note: The path itself is a raw path so you don't need to add the switch r and drop it.

Additionally, ensure that /etc/hosts on your system contains the following entry :

127.0.0.1 localhost.localdomain localhost
#or
127.0.0.1 localhost loopback
