ISSUE IN CONNECTING py2neo v4 to my neo4j server - neo4j

Question

I want to connect my neo4j's project server to py2neo in jupyter
I actually have 2 problems:
Given below is a picture of my neo4j browser connected with bolt//:localhost:11004, username: neo4j, password: password
But i am not able to connect to this server through py2neo on jupyter notebook.
The code in python is the following:
graphdb = Graph("bolt://localhost:11004", secure=True, auth=('neo4j', 'password'))
I am getting the following error:
KeyError Traceback (most recent call last)
~/conda3/lib/python3.6/site-packages/py2neo/database.py in __new__(cls, uri, **settings)

89 except KeyError:

During handling of the above exception, another exception occurred:

What i want to know is
1) The connection between neo4j and py2neo is made how exactly in py2neo v4
2) Do i always have to make a local connection or can i connect to the neo4j server
3) If i can connect to my neo4j server is it such that whatever py2neo queries i run on my jupyter notebook shall synchronise with the neo4j database too?

Answer 1

From the last line of the error, it looks like it's trying to connect on default bolt port (i.e. 7687).
I would suggest you use this format instead of full URI.
graphdb = Graph(scheme="bolt", host="localhost", port=11004,
secure=True, auth=('neo4j', 'password'))
