Using proxy not working anymore?

[Rapid1898-code]

Hello - i try to use the following code to use my proxies using cdp_mode -
(this worked fine for a long time - but now i get a prompt to login in when i want to use th e proxies)

import os, sys
from seleniumbase import SB
import requests
import random
from dotenv import load_dotenv

path = os.path.abspath(os.path.dirname(sys.argv[0])) 
fn = os.path.join(path, ".env")
load_dotenv(fn) 
LINK_BUYPROXIES = os.environ.get("LINK_BUYPROXIES")

resp = requests.get(LINK_BUYPROXIES)
worker = resp.text.split("\n")
proxyList = []
for e in worker:
  e = e.split(":")
  if len(e) < 4:
    continue
  e = f"{e[2]}:{e[3]}@{e[0]}:{e[1]}"
  proxyList.append(e)
proxy = random.choice(proxyList)
print(f"Working with proxy {proxy}")
link = "https://www.wieistmeineip.de/"

with SB(uc=True, proxy=proxy) as sb:
  sb.activate_cdp_mode(link)  
  input("Press!")

The proxy i want to use looks like that:
Working with proxy user:pw@165.231.164.218:12345

But the site open with that:

It's working for me: https://github.com/mdmintz/undetected-testing/actions/runs/19169027029/job/54796598348#step:18:21

Make sure you're using the latest version of SeleniumBase.

And since @ and : are delimiters in the proxy string (used to separate the components of user:pass@ip:port), make sure that your username and password don't contain @ or : in them.

Also, note that proxy auth is handled when activating CDP Mode. (Meaning that if you launch a UC Mode browser and navigate to a site before activating CDP Mode, then proxy auth wouldn't be active yet).
