Failed to establish secure connection to 'EOF occurred in violation of protocol (_ssl.c:1123)

[BroadbentT]

Running as root on Kali linux 2019 full dist-upgrade, running neo4j bolt and bloodhound.

Followed your update regarding the drivers:

python -m pip install 'neo4j-driver==1.7.0' --force-reinstall
python -m pip install 'neo4j==1.7.0' --force-reinstall
python -m pip install -U ldap3
python -m pip install aclpwn

However. when I run the correct command I get the following error message. I think it has something to do with this (driver = GraphDatabase.driver(uri="bolt://localhost:7687", auth=("neo4j", "12345"), encrypted=False)) the encrypted=False bit, but do not know where to change this!!

Regards Tez.

The above exception was the direct cause of the following exception:

Were you ever able to resolve this? We're running into the same thing.

Please use the previews version of neo4j driver.
pip install neo4j-driver==1.6.2
and
this is now supported with the --dns-timeout parameter
