Neo4j into Drupal implementation


I am new to Neo4j and want to implement a graph database into a Drupal website. For this implementation I use this model: Neo4j | The Neo4j server is hosted on an Amazon Web Server. When installing the module in Drupal and connecting to Neo4j it gives the following error: "the website encountered an unexpected error. please try again later." and the whole Drupal site crashes.

Anyone had the same issue or knows what could be wrong?


Did you pass in username and password?

You have the wrong port, correct is: 7687 (which also has to be open in your firewall rules)
