2 years ago Hi, can you try curl from the same host and see if the neptune endpoint is reachable. It could be a reachability/SG/VPC issue..
Also, how are you providing the credentials and the SERVICE_REGION values to the runtime? You can set up credentials through environment variable, or profile, or System property. SERVICE_REGION needs to be an environment variable.

If i enable iam authentication to neptune , its timing out with exception . I followed the https://github.com/aws/amazon-neptune-gremlin-java-sigv4/blob/master/src/main/java/com/amazon/neptune/gremlin/driver/example/NeptuneGremlinSigV4Example.java same example
Here is the full log
