Chrome not reachable error when running Selenium test on Linux

I recently faced a Chrome not reachable error while running a Selenium test in Chrome browser on a Ubuntu machine. I had a hard time isolating the problem because I was trying to get setup with Chrome driver on Ubuntu as part of a Docker image.


selenium.common.exceptions.WebDriverException: Message: chrome not reachableChrome Not reachable Issue


Initially, I suspected the error is because of the below issues:
1. Xvfb display, not getting set properly
2. Chrome driver version/environment issue

Even after making sure that these were set properly I still got this error. After quite a bit of Googling, I came across this particular StackOverflow solution which helped me resolve my issue. The solution was to add a couple of arguments (no-sandbox, disable-setuid-sandbox) when starting up Chrome.

Since I did not understand the solution, I got more info on what Chrome’s Linux sandbox means from this link. The Chrome-Sandbox SUID Helper Binary launches when Chrome does and sets up the sandbox environment. The sandbox environment is meant to be restrictive to the file system and other processes, attempting to isolate various Chrome parts (such as the renderer) from the system.

Adding arguments to disable the sandbox and no sandbox helped me get past my issue and running my tests again

#Selenium script to print the title of
from selenium import webdriver
from import Options
chrome_options = Options()
#argument to switch off suid sandBox and no sandBox in Chrome 
driver = webdriver.Chrome(chrome_options=chrome_options)
print driver.title

Hope this post helps you get past the Chrome not reachable error. Happy testing!

  1. Hi Avinash,
    Thanks for the detailed articled. I’ve been facing this issue intermittently for few days now and the frequency has just increased. I’m running my scripts on Windows and the below code worked for me.
    chrome_options = webdriver.ChromeOptions()

    Also the below thread on stack overflow helped.

    But i see that sometimes even the above solution sometimes doesn’t work( 1 out of 4 times). I’m still monitoring it. Have you faced any such issue after this solution?

  2. Hi Avinash,
    Thanks for the tip. I’m having the exactly same problem. Sorry to say but adding chrome_options did not solve the issue. I’m running a freshly installed Ubuntu 16.04 and Chrome, chromedriver and selenium are installed. The problem occurs both with Python 2.7 and 3.4.

    1. SOLVED!
      Figuring out that the problem is not reaching Chrome, I started Chrome from my X. It did not start… so I thought that maybe there is a problem because I have Chromium web browser open. So, I closed Chromium and started Chrome, and it started.

      Then I ran the python script to test the connection and… tadaa… it WORKED!! :))

      Funnily, after that I can have Chromium open, and the script works anyway. So, I really don’t know why.

      By the way, I didn’t need setting the chrome_options parameters, at all. It works quite well without any of them.

      Just thought I would let you know…:))

  3. hey this works for WSL issue with chromedriver and selenium-python. I was trying to access a website but kept getting “chrome not reachable”. Thanks!

  4. i have set up on remote server, and my config is:
    options = webdriver.ChromeOptions()
    # options.headless = True
    # options.binary_location = binary_path
    self.driver = webdriver.Chrome(executable_path = binary_path, chrome_options=options)
    but not working for me
