SSL Certificate Verification Failed - When using WebDriverManager in Python Selenium framework

Question

I am using Python Selenium framework. In here, to launch the chrome browser, instead of giving chrome binary (chrome.exe) path, I am trying to use WebdriverManager to get the latest version of Chrome driver (based on browser version). Below is the code for that -

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
import time

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

driver.get("https://google.com")
time.sleep(2)
driver.close()

When I run this file, I get SSL Verification error. Below is the Console output -

[WDM] - 

[WDM] - ====== WebDriver manager ======
[WDM] - Current google-chrome version is 94.0.4606
[WDM] - Get LATEST driver version for 94.0.4606

I have tried updating webdriver-manager, requests, urllib3 using pip. But it doesn't work.

Answer 1

Rootcause: That's an issue of your VPN/Proxy or corporate network.

webdriver-manager is not the cause.

There are two solutions:

1. install valid certificates in your certificate chain, check common october 2021 ssl problem with certificates
2. webdriver-manager will have solution soon - a feature to disable SSL verification in next release 3.5.2 (today is 3.5.1), this feature is already in master branch, see CHANGELOG .

Answer 2

WDM_SSL_VERIFY SSL verification can be disabled for downloading webdriver binaries in case when you have troubles with SSL Certificates or SSL Certificate Chain. Just set the environment variable WDM_SSL_VERIFY to "0".

import os

os.environ['WDM_SSL_VERIFY'] = '0'
