Selenium Grid Remote Third party proxy not working

Question

Currently using the selenium hub and node configuration and using the Python test connecting to hub using 4444. When I provide the proxy, the requests are not routing it through.

Using below stack: Python 3 Selenium 4.X

k8 yaml for hub

Python code to connect to the server:

chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument('--disable-dev-shm-usage')
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument('--headless=chrome')
    proxy2 = webdriver.Proxy()
    proxy2.proxy_type = ProxyType.MANUAL
    proxy2.http_proxy = PRX
    proxy2.httpProxy = PRX
    proxy2.ssl_proxy = PRX
    proxy2.sslProxy = PRX
    proxy2.no_proxy = ""
    chrome_options.proxy = proxy2
driver = webdriver.Remote(
        command_executor="http://localhost:4444/wd/hub", options=chrome_options, 
    )

Tried this one as well

pluginfile = "proxy_auth_plugin.zip"

        with zipfile.ZipFile(pluginfile, "w") as zp:
            zp.writestr("manifest.json", manifest_json)
            zp.writestr("background.js", background_js)
        chrome_options.add_extension(pluginfile)

I observed the proxy logs and no logs present this could be the indication.
