cloudflare challenge

[naweed1992]

Hi, I have passed cloudflare challenge using seleniumbase, but somehow from yesterday everything broke down, my code does not work anymore. I share my code, I will be pleased if you help me to get through this problem. I have to mention that I am running this code on Ubuntu server.

import asyncio
import json
import os
from typing import Literal

from loguru import logger
from seleniumbase import SB as seleniumBase

logger.add("logs/log-of-{time:YYYY-MM-DD}.log", rotation="4 week")
logger.debug("That's it, Chiron Captcha is simple Like it!")


async def solve_cloudflare_captcha(
    cookies: list[dict], proxy: str, url: str = "https://x.com/"
) -> dict[Literal["cookies", "user_agent", "html_content"], str | dict]:
    proxy = proxy.removeprefix("http://").removeprefix("https://").removesuffix("/")
    logger.info(f"Launching browser session with proxy {proxy!r}")

    # Detect if DISPLAY is available, otherwise enable xvfb
    use_xvfb = False
    if "DISPLAY" not in os.environ or not os.environ["DISPLAY"]:
        logger.warning("No DISPLAY found -> enabling Xvfb virtual display")
        use_xvfb = True

    with seleniumBase(
        uc=True,
        headed=True,          # visible window (or virtual one if xvfb=True)
        headless=False,       # must be False for GUI automation
        test=True,
        locale="en",
        xvfb=use_xvfb,        # auto-enable xvfb if DISPLAY missing
        proxy=proxy,
    ) as sb:
        logger.info(f"Opening URL: {url}")
        sb.open(url)

        logger.info("Adding cookies to session...")
        sb.add_cookies(cookies)

        logger.info("Refreshing the page to apply cookies...")
        sb.refresh()

        html = sb.get_page_source()
        logger.info(f"HTML content on homepage {html[:200]}")
        logger.info("Attempting CAPTCHA interaction...")

        sb.uc_gui_click_captcha()  # GUI click for Cloudflare checkbox

        sb.wait_for_ready_state_complete()

        unlock_account_button = 'input[type="submit"]'
        first_page_element = "ul.TextGroup-list"
        if sb.is_element_present(unlock_account_button) and not sb.is_element_visible(
            first_page_element
        ):
            sb.click(unlock_account_button)
            logger.info("Submit button found and clicked")
        else:
            logger.error("Submit button not found")

        logger.info("Extracting updated cookies from browser...")
        cookies = sb.driver.execute_cdp_cmd("Network.getAllCookies", {})["cookies"]

        logger.info("Retrieving user-agent string...")
        user_agent = sb.execute_script("return navigator.userAgent;")

        logger.info("Grabbing page HTML content...")
        html = sb.get_page_source()
        logger.info(f"HTML content on page after solving {html[:200]}")

        if "Just a moment..." in html or sb.get_page_title() == "Just a moment...":
            logger.warning("Cloudflare challenge can't be solved")
            return False

        result = {
            "cookies": json.dumps(cookies),
            "user_agent": user_agent,
            "html_content": html,
        }

        logger.success("Cloudflare challenge solved successfully")
        return result


# === Run the script ===
if __name__ == "__main__":
    # === Proxy Configuration ===
    proxy_url = ""

    # === Cookies for Twitter Session ===
    cleaned_cookies = []

    session_data = asyncio.run(
        solve_cloudflare_captcha(cookies=cleaned_cookies, proxy=proxy_url)
    )

    if session_data:
        logger.info("Session output:")
        logger.info(f"User Agent: {session_data['user_agent']}")
        logger.info(f"Cookies Count: {len(session_data['cookies'])}")
        logger.info(f"HTML Length: {len(session_data['html_content'])}")
    else:
        logger.error("solving failed")

I am also facing the same problem and unfortunately the problem was not solved on my system today and I clicked in the wrong place which causes the rest of the steps to fail due to not passing the captcha.

[naweed1992]

are you working on windows or ubuntu?

[HELA-HELA]

I use both operating systems, Apple MacOS and Windows, and there are problems on almost all of them!!

It looks like you're calling WebDriver methods from CDP Mode, which either doesn't work, or is detectable.

sb.add_cookies(cookies) calls the WebDriver method add_cookie on the backend:

https://github.com/seleniumbase/SeleniumBase/blob/master/seleniumbase/fixtures/base_case.py#L4786

And sb.driver.execute_cdp_cmd is a WebDriver method.

There are CDP Methods for cookies. Here's an example that uses that: examples/cdp_mode/raw_cookies_async.py.

CDP Mode methods are listed at the bottom of SeleniumBase/examples/cdp_mode/ReadMe.md.

As for running in Ubuntu, there have been no issues bypassing Cloudflare Turnstiles.
