Implementing MSNP15 in Python - 911 error but all tickets are correct

I am working on implementing the MSNP15 protocol in Python. I have verified that my hashing and encryption functions are working (or at least, they match up with examples I found online), however I am always receiving a 911 error back from the server.

Thanks for any help.

Python code is as follows;

msntest.py:

import socket
import httplib
from encryption import GetSSOTicket

username = "login@hotmail.com"
password = "password"

def ReadAll(sock):
    data = ""
    while 1:
        try:
            r = sock.recv(4096)
            data += r
        except socket.timeout:
            break
    return data


def SOAPRequest(xml):
    url = "login.live.com"
    con = httplib.HTTPSConnection(url)

    headers = {"Host": "login.live.com",
                "Accept": "text/plain"}

    con.request("POST", "/RST.srf", xml, headers)

    response = con.getresponse().read()

    con.close()

    return response

Modified your msntest.py a little and now it should work:
