Я пытаюсь получить доступ к API BambooHR (документация здесь), но я получаю следующую ошибку

    params = {
        'user': username,
        'password': password,
        'api_token': api_key}
    url = 'https://api.bamboohr.com/api/gateway.php/company/v1/login'
    r = requests.get(url, params=params)

Ошибка:

Я не уверен, чем это вызвано, поскольку я переустановил OpenSSL, запросы и не уверен, как решить эту проблему.
