i am facing the same problem Error connecting to Selenium server: HTTPConnectionPool(host='172.17.0.4', port=4444): Max retries exceeded with url: /wd/hub (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fed96b68b60>: Failed to establish a new connection: [Errno 113] No route to host'))

I did update the URL from my standalone browser

driver = webdriver.Remote( command_executor='http://172.17.0.4:4444/wd/hub', # Correct IP address for Selenium Hub options=chrome_options, )
