[🐛 Bug]: Exception managing MicrosoftEdge: error sending request for url (https://msedgedriver.microsoft.com/LATEST_RELEASE_139_WINDOWS)

[cavapoo2]

Description

Here's my code I'm trying to run. Python version 3.13. Edge browser version is 139.0.3405.86, selenium version 4.35.0,
Windows 10 22H2

What I would like to do is run it headless.

The code hangs for a few seconds, then another browser windows appears.

I've tried many permutations with these Options and Service, but no luck

`
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.edge.service import Service
from selenium.webdriver.edge.options import Options
import os
import time
os.environ["SE_DRIVER_MIRROR_URL"] = "https://msedgedriver.microsoft.com"
driver = webdriver.Edge()

del os.environ["SE_DRIVER_MIRROR_URL"]

driver.get('https://bing.com')

element = driver.find_element(By.ID, 'sb_form_q')
element.send_keys('WebDriver')
element.submit()

time.sleep(5)
driver.quit()
`

@cavapoo2, thank you for creating this issue. We will troubleshoot it as soon as we can.

Selenium Triage Team: remember to follow the Triage Guide

[cavapoo2]

Note I'm behind a firewall. My Edge browser is already open before running that program.
tried
selenium 4.36.0.202508140013
also same exception

[diemol]

The Edge url changed and most likely you need to update your firewall to account for that.

[cavapoo2]

@diemol no idea what you mean, how to resolve ?

[diemol]

Check your firewall rules and allow the URL to be reached. This is out of the scope of Selenium.

[cgoldberg]

@cavapoo2 also, you no longer need to set os.environ["SE_DRIVER_MIRROR_URL"] if you are running the selenium 4.35+. The new releases contain the correct URL (although this won't solve your firewall issue)

My Edge browser is already open before running that program.

Having it open doesn't matter. Selenium will launch a new browser.

[cavapoo2]

ok, thanks. Confusing part for me is even with the firewall I have no problem running the Playwright python. It's using the headless chromium binary. Any outbound calls must go through this headless chromium binary (which is maybe why it gets through the firewall ?). The Selenium setup maybe makes outbound call outside of the driver, and I'm assuming this is why nothing works.

[cgoldberg]

Selenium does not include webdrivers with it (chromedriver, edgedriver, etc). Selenium Manager will attempt to download a driver and browser if either is not on your PATH.

Playwright communicates with the browser directly and doesn't use anything analogous to a webdriver. It also includes browsers as part of its installation rather than using your system browser or downloading them externally.

[cavapoo2]

@cgoldberg I'm sure I set the webdriver in my path, yet still it was trying to call out. Will look into it again maybe, and see if there's some way of explicitly setting things in the Selenium Manager
