user_data_dir & proxy

[Allmight3]

Hello.

This code works well for me. It creates a local directory profile, uses the proxy and adds my extensions.

driver = Driver(uc=True, headed=True, proxy=PROXY, user_data_dir=absolute_profile_directory, page_load_strategy="eager", extension_dir=extensions_dir)

My issue is when I want to come back to this profile later, it requires authentication from the proxy I used when I created it. The problem is, I rotate proxies and the authentication changes.

I tried regular Selenium:

options = webdriver.ChromeOptions()
options.add_argument(f'--user-data-dir={folder_path}')

As well as SB:
driver = Driver(uc=True, headed=True, user_data_dir=folder_path)

I just want to load that profile back up without a proxy requirement. I also snooped around in the profile folder looking to see where the proxy information was being stored, so I could delete it programmatically before launching. However I couldn't find that information. It wasn't in Preferences or anywhere else that I had noticed.

Am I trying to do something that's unsupported? If so, is there a work-around -- such as deleting where the proxy data is stored before relaunching the profile?

Thank you

To disable proxy settings for regular Selenium, use https://stackoverflow.com/a/49033706/7058266:

chrome_options.add_argument("--no-proxy-server")

With SeleniumBase, those options get passed via chromium_arg: (comma-separated for multiple)

chromium_arg="--no-proxy-server"

With the Driver(), that would be this:

driver = Driver(chromium_arg="--no-proxy-server")

Hi, I am still having same issue with driver = Driver(chromium_arg="--no-proxy-server", browser="chrome", user_data_dir=session_dir, headless=False, undetected=True), keeps asking to reauthenticate. I even deleted the proxy file from downloaded_files directory.

@epictroller64 You probably mixed your UC Mode user_data_dir with a non UC Mode Chrome. (You can't "cross the streams".) Try from a brand new user_data_dir, or don't specify one at all when you run your script.

Seems the only solution is to delete user_data_dir but I really need to carry the session data over after changing proxy. Creating new profile worked only once, after I removed the proxy and used chromium_arg="--no-proxy-server", it still showed old details.

@epictroller64 You probably need to disable extensions:
chromium_arg="--no-proxy-server,--disable-extensions"

(Proxy details are configured via Chrome extension in SeleniumBase.)

Also, make sure you're not mixing a non UC Mode Chrome user_data_dir with a UC Mode Chrome user_data_dir.
If you "cross the streams", you'll need to start with a fresh user_data_dir for things to work.

I found that creating the profile using UC mode and a proxy with username:pass authentication will cause the profile to always require that same proxy.

If you create a profile using UC mode and a proxy without username:pass, then it will work normally as expected. So that's what I did. If you only have proxies with username authentication then you could use proxy.py perhaps to forward the proxy, then use the downstream proxy to create the profiles.
