Селен - добавить куки, которые не работают спорадически?

Question

Вот мой код:

водитель

def dl_driver(dl_path,display):
    pf = webdriver.FirefoxProfile()
    pf.set_preference("browser.download.folderList", 2)
    pf.set_preference("browser.download.manager.showWhenStarting", False)
    pf.set_preference("browser.download.dir", dl_path)
    pf.set_preference("browser.helperApps.neverAsk.saveToDisk",
                      "text/plain,text/x-csv,text/csv,application/vnd.ms-excel,application/csv,"
                      "application/x-csv,text/csv,text/comma-separated-values,text/x-comma-separated-values,"
                      "text/tab-separated-values,application/pdf,application/octet-stream")
    # pf.set_preference("browser.link.open_newwindow", 1)
    # pf.set_preference("browser.link.open_newwindow.restriction", 0)
    options = Options()
    options.set_preference("browser.link.open_newwindow.restriction", 0)
    options.set_preference("browser.link.open_newwindow", 1)
    if display.lower() == 'on':
        driver = webdriver.Firefox(firefox_profile=pf,options=options)
    else:
        options = Options()
        options.headless = True
        driver = webdriver.Firefox(options=options, firefox_profile=pf)
    return driver

Тогда

driver = dl_driver('path/to/download/', display='on')
driver.get('driver.get(url='https://sellercentral.amazon.in/gp/homepage.html')
cookies = pickle.load(open("cookies.pkl", "rb"))
# the cookies were dumped with: pickle.dump(driver.get_cookies(), open("cookies.pkl", "wb"))
for cookie in cookies:
    driver.add_cookie(cookie)
# Then I enter password and click signin

Работало нормально до пары дней go, но теперь это запрашивает OTP при каждом доступе.

Что-то не так с кодом выше?
