Invalid argument in authentication request

Hi! I'm trying to authenticate using POST request, but got response "Invalid argument" and code 301.

I'm generating random int using "self.rand_int = randint(0, (1 << 32) - 1)", also I tried to use "2144632130" value, which I get in documentation, but nothing changed.

My code given below:

def get_token(self):

    rand_int = 2144632130

    api_address = f"https://{self.get_ip_address}:7443/sangforinter/v1/auth/party/login?verify=False"

    auth_string = hashlib.sha1(f"{rand_int}{self.get_password}sangfor3party{self.get_username}".encode('utf-8')).hexdigest()

    data = {

            'rand': rand_int,

            'userName': self.get_username,

            'clientProduct': '',

            'clientVersion': '',

            'clientId': '',

            'desc': '',

            'auth': auth_string,

            'platformName': self.get_platform_name

        }

    response = post(url=api_address, data=data, verify=False)

    return response.text

Any help would be very appriciated. Thanks in advance!
