                             proxy=proxy,
                             timeout=3600,

You’re trying to configure a proxy with authentication in Selenium using a Remote WebDriver (Selenium Grid), but the challenge is that Selenium’s --proxy-server argument does not support username and password authentication by default.

Option 1

You need to bypass this by using methods like Selenium Wire
https://www.zenrows/blog/selenium-proxy#proxy-authentication-selenium
PS: Its no longer maintained but i'm not sure about an alternative

Option 2

Create a Chrome Extension to inject proxy authentication.
Step 1 :create an script to create the extension

import zipfile

PROXY_HOST = "proxyserver"
PROXY_PORT = "8080"
PROXY_USER = "admin"
PROXY_PASS = "myStrongPassword"

def create_proxy_extension():
    manifest_json = """{
        "version": "1.0.0",
        "manifest_version": 2,
        "name": "Chrome Proxy",
        "permissions": ["proxy", "webRequest", "webRequestBlocking", "<all_urls>"],
        "background": {"scripts": ["background.js"]}
    }"""

    background_js = f"""
    var config = {{
        mode: "fixed_servers",
        rules: {{
            singleProxy: {{
                scheme: "http",
                host: "{PROXY_HOST}",
                port: parseInt({PROXY_PORT})
            }},
            bypassList: ["localhost"]
        }}
    }};
    chrome.proxy.settings.set({{value: config, scope: "regular"}}, function() {{}});
    chrome.webRequest.onAuthRequired.addListener(
        function(details) {{
            return {{
                authCredentials: {{
                    username: "{PROXY_USER}",
                    password: "{PROXY_PASS}"
                }}
            }};
        }},
        {{urls: ["<all_urls>"]}},
        ["blocking"]
    );
    """

    with zipfile.ZipFile("proxy_auth_plugin.zip", "w") as zp:
        zp.writestr("manifest.json", manifest_json)
        zp.writestr("background.js", background_js)

create_proxy_extension()

Step 2

load the extension into Selenium Chrome WebDriver:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_extension("proxy_auth_plugin.zip")
driver = webdriver.Chrome(service=Service("/path/to/chromedriver"), options=chrome_options)
driver.get("https://www.selenium.dev")
driver.quit()

ChromeOptions has an --proxy-serveroption:
https://developer.chrome/docs/chromedriver/capabilities

#!/usr/bin/env python3
import time
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService

options = webdriver.ChromeOptions()
# profile where you have predefined all your stuff
#options.add_argument('user-data-dir=C:\\Users\\mobj\\AppData\\Local\\Google\\Chrome\\User Data\\Default')

# if not using a predefined profile you might need the following
#options.add_argument("--incognito")
#options.add_argument("--disable-search-engine-choice-screen")

# for proxy
#proxy = "proxy.XXXX.YYYY:3128"
#options.add_argument(f"--proxy-server={proxy}")

# do not need path if  chromedriver if its in your PATH
service = ChromeService(service_args=['C:\\dist\\webdrivers\\chromedriver.exe', "--verbose", "--log-path=./chromedriver.log"])
driver = webdriver.Chrome(service=service, options=options)
driver.get('https://www.google.no')
# just to keep the window open
time.sleep(100000)
