I'm currently trying to access the AWS Neptune Server, but I receive the error below when trying to connect.
I'm following this tutorial from AWS, yet without success: https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin.html
Has anyone encountered this issue before?
I thought it was because of the inbound/outbound rules, but it didn't work even when I allowed all traffic.
The endpoint is also correct. Double checked.

hosts: [neptuneTest.cu7geofyk01wr.us-east-1.neptune.amazonaws.com]
port: 8182
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV3d0, config: { serializeResultToString: true }}
