NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f8374a801d0>: Failed to establish a new connection: [Errno 111] Connection refused

[zhoujs93]

I have been getting the following error:

Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f8374a6f0d0>: Failed to establish a new connection: [Errno 111] Connection refused')': /session/c1ec428988d418ea8126f2afcf645f80/execute/sync

This is the code which I am running:

def setup_stealth_chrome_driver(proxy=None):
    # service = ChromeService(executable_path='./data/chromedriver')
    options = ChromeOptions()
    options.add_argument(f"user-agent={get_random_user_agent()}")
    options.add_argument("--disable-blink-features=AutomationControlled")
    options.add_argument("--headless")  # If you need headless mode
    options.add_argument("--log-level=ALL")
    options.add_argument("--verbose")
    seleniumwire_options = {}

    if proxy:
        # logger.info(f'Setting up proxy: {proxy}')
        # options.add_argument(f'--proxy-server={proxy}')

        seleniumwire_options = {
            'proxy': {
                'http': proxy,
                'https': proxy,
                'no_proxy': 'localhost,127.0.0.1',  # Bypass proxy for local addresses
            }
        }

        # driver = webdriver.Chrome(service=service, options=options, seleniumwire_options=seleniumwire_options)
    driver = uc.Chrome(options=options, seleniumwire_options=seleniumwire_options)
    driver.set_page_load_timeout(60)
    driver.set_script_timeout(60)
    # Apply stealth mode
    stealth(driver,
            languages=["en-US", "en"],
            vendor="Google Inc.",
            platform="Linux",
            webgl_vendor="Intel Inc.",
            renderer="Intel Iris OpenGL Engine",
            fix_hairline=True,
            )

    return driver

And this is the code where I am using the web driver:

def main(proxy):
    driver = setup_stealth_chrome_driver(proxy=proxy)
    clear_browser_data(driver)

    try:
        account_number = login(driver)
        time.sleep(180)
        logger.info(f'account number is: {account_number}')
        index = 1
        element_exists = False
        start_time = random.randint(0, 30)
        end_time = (start_time + 29)
        logger.info(f'start time is: {start_time} and end_time is {end_time}')
        found_during_hour = False
        pst = pytz.timezone('America/Los_Angeles')
        current_hour = datetime.datetime.now(pst).hour
        start_datetime = datetime.datetime.now(pst)
        num_games = 0
        element_exists = locate_by_xpath(driver,
                                         '/html/body/div[11]/div[2]/div[2]/button[2]', timeout=15)
        if element_exists:
            button = WebDriverWait(driver, 30).until(
                EC.element_to_be_clickable((By.CSS_SELECTOR, 'button.text-xs'))
            )
            button.click()
            css_selector = 'button.relative:nth-child(2)'
            button = WebDriverWait(driver, 30).until(
                EC.element_to_be_clickable((By.CSS_SELECTOR, css_selector))
            )
            button.click()
            time.sleep(5)
        while True:
            current_time = datetime.datetime.now(pst)
            if current_time.hour != current_hour:
                current_hour = current_time.hour
                found_during_hour = False  # Reset the flag for the new hour

Note that in addition I am running this in multiple threads as well where each thread is running their own webdriver. Does anyone know how to debug this error ?

Did you figure this out? I have the same problem. Mutliple processes seem to be interfering with each other somehow.

I am getting this kind of error too. This happens on scripts which used to work. Now it doesn't work on
Ubuntu 22.04.1 LTS
Google Chrome 126.0.6478.61
undetected-chromedriver==3.5.5

but exactly same script works on
MacOS 12.0.1
Google Chrome 126.0.6478.62
undetected-chromedriver==3.5.5
