[Char-Cp]

What happened?

opt_einsum = webdriver.ChromeOptions() opt_einsum.set_capability('browserVersion', '127.0') proxy = "xxx:x" opt_einsum.add_argument(f'--proxy-server=socks5://{proxy}') opt_einsum.add_argument(f'--proxy-auth=xxx:xxx') print(opt_einsum)

Command used to start Selenium Grid with Docker (or Kubernetes)

opt_einsum = webdriver.ChromeOptions()
    opt_einsum.set_capability('browserVersion', '127.0')
    proxy = "xxx:x"
    opt_einsum.add_argument(f'--proxy-server=socks5://{proxy}')
    opt_einsum.add_argument(f'--proxy-auth=xxx:xxx')
    print(opt_einsum)

@diemol, Do you think this issue and also this SeleniumHQ/selenium#14434
Which relates to the issue of a few capabilities getting filtered in the session response?

[diemol]

Those don't get filtered. They are part of ChromeOptions.

[VietND96]

@Char-Cp, instead of setting args from binding, can you try to use feat in docker-selenium to add args to browser directly via env vars - https://github.com/SeleniumHQ/docker-selenium?tab=readme-ov-file#se_browser_args_-add-arguments-for-launching-browser
For example, adding these env vars and confirm

- SE_BROWSER_ARGS_PROXY_SERVER=socks5://your.proxy.ip.addr
- SE_BROWSER_ARGS_PROXY_AUTH=username:password

@VietND96 ，The image I used is selenium/node-chrome:4.23.1-20240820. I tried it according to your method, but it didn't work.

[Char-Cp]

@VietND96 I tried the following methods. None of them can achieve proxy
-e SE_BROWSER_ARGS_PROXY_SERVER=socks5://ip:port -e SE_BROWSER_ARGS_PROXY_AUTH=user:password
-e SE_BROWSER_ARGS_PROXY_SERVER=socks5://user:password@ip:port
