    I'm unable to connect to Neo4j using neo4j-python-driver version 5.3.0. Requirement is using Neo4j python driver to query NEO4J DB using cypher queries. It gives the error failed to connect to server even when the database is up and running and i can able to login and use through NEO4J Desktop. Getting below error

    neo4j.exceptions.ServiceUnavailable: Couldn't connect to <URI>:7687 (resolved to ()):
    [SSLCertVerificationError] Connection Failed. Please ensure that your database is listening on the correct host and port and that you have enabled encryption if required. Note that the default encryption setting has changed in Neo4j 4.0. See the docs for more information. Failed to establish encrypted connection. (code 1: Operation not permitted)


    Note : URI hided in the above error.

    I have added the exception to Ignores certificate verification issue, but it won't solve the issue.

    urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)


    Appreciate your help to resolve the issue.

    i'm connecting via below snippet

    from neo4j import GraphDatabase
    import urllib3

    #Ignores certificate verification issue
    urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)


    # Initialize connection to database
    driver = GraphDatabase.driver('bolt+s://<URI>:7687', auth=(',username', '<password'))


    query = 'match (n:Event{name:"test"}) return n'

    #Run Cypher query
    with driver.session() as session:
    info = session.run(query)
    for item in info:
    print(item)
