the transport is not closed, prefer self.close()

Is it necessary to close the connection here? I tend to release the connection back to the connection pool and wait for the next authenticate
nebula3/gclient/net/Connection.py
Outdated

Authenticate failed does not mean the connection is broken, Why set _connection = None, we can just set _connection.is_used as False.
Let's see the connection pool how to call authenticate function:
def get_session(self, user_name, password, retry_connect=True):
"""get session
:param user_name: the user name to authenticate graphd
:param password: the password to authenticate graphd
:param retry_connect:
:return: Session
"""
connection = self.get_connection()
if connection is None:
raise NotValidConnectionException()
try:
auth_result = connection.authenticate(user_name, password)
return Session(connection, auth_result, self, retry_connect)
except Exception:
raise
the auth operation is undependent with connection, so auth failed does not Influence the connection unless there are IO Error.

I refer to the code under release function of session.py. I think you may right, self._connection.is_used = False is enought here
