I am using the Neo4jVector from langchain community, I can't seem to be able to connect to my instance on aura, I caught the error and printed it

Unable to retrieve routing information Could not connect to Neo4j database. Please ensure that the url is correct

Hi, have you checked that your Aura instance is running, and that port 7687 is available for network traffic?
