Org.Openqa.Selenium.Webdriverexception: Chrome Not Reachable - When Attempting to Start a New Session

org.openqa.selenium.WebDriverException: chrome not reachable - when attempting to start a new session

The error does gives us some hint as follows :

org.openqa.selenium.WebDriverException: chrome not reachable

Which essentially implies that chromedriver binary is unable to spawn a new Chrome Browser process.

Your main issue is the version compatibility among the binaries you are using as follows :

• You are using chromedriver=2.35.528161 (released 2018-01-10)
• Release Notes of chromedriver=2.35 clearly mentions the following :

Supports Chrome v62-64

• You mentioned of using latest Chrome. I suppose it is chrome=65.x
• You are using Selenium Version 2.52.0 (released 2016-02-11 11:22:43) [as per the error stack trace within your question]

So the time gap between the release of Selenium Version 2.52.0 and chromedriver=2.35.528161 is almost 2 Years and are not compatible. Hence ChromeDriver is unable to spawn the new Chrome Browser process at times.

Solution

• Keep the ChromeDriver at v2.35 level.
• Downgrade Chrome to stable Chrome v64.x levels. (as per ChromeDriver v2.35 release notes)
• Upgrade Selenium to current levels Version 3.8.1.
• Execute your Test.

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: Message: chrome not reachable after long time

Initially I had asked myself the same questions as @GregBurghardt had been asking in the comments till I analyzed the detailed error stack trace.

Yes, there is somehting amazing happening in those steps marked as #do thing that require hours. Hence, instaed of showing Chrome browser version as chrome=76.0, chrome=75.0 or chrome=74.0 it shows:

(Session info: chrome=192.168.0.0)

which is pretty much surprising.

It would be almost impossible to analyze the issue until and unless you update us why and how the Chrome version gets changed to such value.

Having said that, possibly your main issue is the incompatibility between the version of the binaries you are using.

• You are using chromedriver=2.36
• Release Notes of chromedriver=2.36 clearly mentions the following :

Supports Chrome v63-65

• Presumably you are using the latest chrome= 76.0
• Release Notes of ChromeDriver v76.0 clearly mentions the following :

Supports Chrome version 76

• Your Selenium Client version is unknown to us.

So there is a clear mismatch between the ChromeDriver v2.36 and the Chrome Browser v76.0

Solution

Ensure that:

• Selenium is upgraded to current levels Version 3.141.59.
• ChromeDriver is updated to current ChromeDriver v76.0 level.
• Chrome is updated to current Chrome Version 76.0 level. (as per ChromeDriver v76.0 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test as non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.

Win 10, python 3.8 selenium 3.141 WebDriver error: Message: chrome not reachable

Try to get your correct driver with

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())

if you don't have it installed :

pip install webdriver_manager

This package will handle all the manual complications of finding the correct driver.
