Ошибка URL в Droplet

Question

Следующий скрипт отлично работает на моем ноутбуке:

for elem,i in zip(range(10000), bar((range(10000)))):

    n = random.uniform(.01, 2)
    time.sleep(n)
    driver = webdriver.PhantomJS(desired_capabilities=desired_capabilities)
    driver.set_window_size(1120, 550)
    search_url = "https://www.parlament.ch/de/ratsbetrieb/amtliches-bulletin/amtliches-bulletin-die-videos?TranscriptId=" + str(elem)
    driver.get(search_url)

    try:
         element_present = EC.presence_of_element_located((By.XPATH, '//p[="ng-scope"]'))
         WebDriverWait(driver, 10).until(element_present)
    except:
         pass

    text = (driver.page_source).encode('utf-8')

    with open(time.strftime("parl_htmls/" + "%Y%m%d%H%M%S")+".htm", "wb+") as file:
        file.write(text)
        file.close()

driver.close()

Однако, когда я запускаю из Digital Ocean Droplet, я получаю следующие ошибки:

Traceback (most recent call last):

У кого-нибудь есть идея, как решить эту проблему?
