I am able to connect to graphenedb with version 3 (because I was not able to connect with v4), but after I reinstalled with v4 using the git install, I am not able to log in now. I am following the recommended login method from the documentation, and below is my code.
I am using ubuntu 16.04 and python version 3.5.2.
I have the account and password in the code, and since it's a test database, you can use it for testing. Thanks!
from py2neo import Graph
uri='bolt://hobby-decofbokkgfdgbkemhfoical.dbs.graphenedb.com:24786'
user='Sen'
pwd='b.QS1afdAYIUnb.FWIkIyENscjeVzMJ'
graph = Graph(uri, auth=(user, pwd), port=24786)
And the response is as such,
S: [CLOSE]
Traceback (most recent call last):

Thanks!
Your Neo4J instance is using TLS for its bolt connection, but your py2neo is not.
That traceback is characteristic of trying to connect to a TLS server with a normal, unencrypted connection.
In order to fix this problem, tell py2neo that your bolt connection should use TLS by passing in secure=True to the initialization of your Graph instance:
graph = Graph(uri, auth=(user, pwd), port=24786, secure=True)
