Im trying to connect the Django to Neo4j using neo4j-driver but I'm getting Security error.

Error is :- neo4j.exceptions.SecurityError: Failed to establish secure connection to '[SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:600)'

Python Version 3.4.3 IN MACOSX

My Dependencies

CODE Views.py

from django.shortcuts import render
# Create your views here.
from neo4j.v1 import GraphDatabase,basic_auth
from django.conf import settings
from django.db import IntegrityError
from django.views.decorators.cache import cache_page

from django import template



uri = "bolt://localhost:7474"
driver = GraphDatabase.driver(uri, auth=("neo4j", "password"))


def friends(request):
    name = "Cameron Crowe"
    with driver.session() as session:
        with session.begin_transaction() as tx:
            for record in tx.run("MATCH (a:Person)-[:PRODUCED]->(f) "
                                 "WHERE a.name = {name} "
                                 "RETURN f.title", name=name):
                print(record["f.title"])

    return render(request, "friends.html")

Thanks Rishabh for writing a solution to the question.

I later realized that port number 7474 is used for http protocol for ssl use.

I have changed the URL form uri = "bolt://localhost:7474" to uri = "bolt://localhost:7687"

Worked like charm !!
