urllib3.exceptions.ProtocolError: (‘Connection aborted.’, error(10054, ‘An existing connection was forcibly closed by the remote host’))

I am trying to open a website on chrome using Python Selenium chromedriver. Chrome browser is opening (with warnings) and the url is not opening.

Version details : Chrome : 68.0.3440.106
selenium : 3.14.0
chromedriver : 2.20
python : 2.7

I am using below code :

import time
from selenium import webdriver
import selenium
driver = webdriver.Chrome("C:/Python27/chromedriver.exe")
driver.get("https://vancouver.craigslist.ca/")
print(driver.title)
time.sleep(8)
driver.quit()

I am getting below error:

Method 1

This error message…

urllib3.exceptions.ProtocolError: ('Connection aborted.', error(10054, 'An existing connection was forcibly closed by the remote host'))

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

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• You are using chromedriver=2.20
• Release Notes of chromedriver=2.20 clearly mentions the following :

Supports Chrome v43-48

• You are using chrome=68.0
• Release Notes of ChromeDriver v2.41 clearly mentions the following :

Supports Chrome v67-69

So there is a clear mismatch between ChromeDriver v2.33 and the Chrome Browser v65.0

Solution

• Upgrade ChromeDriver to current ChromeDriver v2.41 level.
• Keep Chrome version between Chrome v67-69 levels. (as per ChromeDriver v2.41 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.
• Execute your @Test.
