Hello I am trying to connect to a neo4j database with py2neo. This code works so far:

graph = Graph(bolt=True, host='***',
              bolt_port=***,
              http_port=***,
              user='***',
              password='***')

But when I protect my IP address with a password over HTTP then I can't connect and I don't know how to authorize py2neo to connect.

Does anyone know how I can solve this? :)

Edit : When I open the ip in a web browser i need to input a user and a password before i can see the neo4j browser - and I do not now how to input these credentias with py2neo (because it seems that this is my problem)

  • `secure=True` does not work for you? (`Graph(...., secure=True,...)`). See also: http://py2neo.org/v3/database.html#the-graph . Also: http://py2neo.org/v3/database.html#module-py2neo.database.auth (see the `authenticate` function) – cowbert Oct 23 '17 at 17:56
  • @cowbert I tried it but every time I run graph.run({query}) i get an error – Benjamin Feldmann Oct 23 '17 at 18:27
  • please update your post with what you tried and the error(s) you received. – cowbert Oct 23 '17 at 18:42
  • The exact error message would be useful as well as how exactly you're doing *But when I protect my IP address with a password over HTTP* - I'm not quite sure how to interpret that... – Jon Clements Oct 23 '17 at 18:49

    This error is showing that the driver cannot parse the SSL response. Make sure the ports you're connecting to actually support HTTPS and not just plain HTTP (are you connecting to the correct secure ports?) – cowbert Oct 28 '17 at 16:32
