ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine

For some reason I get the following error only when I open up a nested webdriver instance. No idea what is happening here.

I am using Windows 10, geckodriver 0.21.0, and Python 3.7.

Here it is in a codepen, since it is wayyy too long!

create_webdriver_instance Function

def create_webdriver_instance():
    options = Options()
    options.add_argument('-headless')
    try:
        ua_string = random.choice(ua_strings)
        profile = webdriver.FirefoxProfile()
        profile.set_preference('general.useragent.override', ua_string)
        return webdriver.Firefox(profile) # profile, firefox_options=options

        print('\nSection: Function to Create Instances of WebDriver\nCulprit: random.choice(ua_strings)\nIndexError: {}\n'.format(error))
        return webdriver.Firefox() # firefox_options=options

Does anybody have any idea whatsoever what might be causing the connection to abort?
