Driver works with undetected_chromedriver but not with seleniumbase

Question

I am currently creating an application which involves 2 webdrivers. One webdriver uses the undetected_chromedriver library and one uses seleniumbase in UC mode:

driver1 = undetected_chromedriver.Chrome(use_subprocess=True, user_multi_procs=True, headless=True)
driver2 = seleniumbase.Driver(uc=True, headless2=True, uc_subprocess=True, incognito=True)

driver1 works fine, however, when attempting to run driver2, sometimes I receive the following error:

session not created: cannot connect to chrome at 127.0.0.1:63728
from chrome not reachable

I have looked for solutions but have had no success, does anybody know why I am receiving this error?

For Linux, you'll want Xvfb instead of Headless Mode.

Use the SB() context manager format:

from seleniumbase import SB

with SB(uc=True, test=True, xvfb=True, incognito=True) as sb:
    sb.activate_cdp_mode(URL)

If using CDP Mode (which is stealthier than regular UC Mode), you'll want to use the sb.cdp methods. Examples in SeleniumBase/examples/cdp_mode.

Otherwise (if using regular UC Mode), then don't activate CDP Mode.

You can access the raw driver methods from regular UC Mode with sb.driver.

Thanks, what should I do if I am using Windows?

On Windows, there's a GUI. Use a regular, visible browser.
