[quote="babu.ganesh0708, post:1, topic:20685"]

Caused by: java.lang.IllegalArgumentException: Setting "dbms.connector.bolt.advertised_address" must be in the format "hostname:port" or ":port". "neo4j-community-neo4j-core-0.neo4j-community-neo4j-core.svc.cluster.local" does not conform to these formats

Not familiar with the HELM environment but somehow that string does not gets translated correctly and neo4j is expecting a valid hostname or ip-address

Add this to extra vars

  • name: NEO4J_dbms_connector_bolt_advertised__address
    value: neo4j-community-neo4j-core-0.neo4j-community-neo4j-core.svc.cluster.local:7687

The host name can be an internal host name or external if you want to be able to access it using external browser.
