SocketError: Connection refused using py2neo to a remote server - authentication

Question

While this issue has been addressed a couple of times in the past at SO and I tried all the suggestions, the problem still remains and I am hoping someone would shine a light on this.
My company set up a neo4j (v2.1.6) graph database at a remote ubuntu server.
In order to modify and update data into the server, I am using a python package, py2neo.
The server's endpoint address is http://fake-address.com/db/data and the authentication Id/password are 'fakeId' and 'fakePassWord'.
In order to access the remote database, in my local machine python terminal,
I tried the following:
from py2neo import authenticate, Graph
authenticate("fake-address.com:80", "fakeId", "fakePassWord")
graph = Graph("http://fake-address.com:80/db/data/")
result = graph.cypher.execute("CREATE (a:Color)")
Unfortunately, the above command resulted in the following error message.

Sorry about the long error message and I greatly appreciate any suggestions.

The issue has been resolved. The problem must have been in the authentication in py2neo. With the newest version of py2neo (2.0.4), the connection was properly made.
