I am trying to access AWS Neptune Database from outside VPC (from laptop) with path User -> API Gateway -> VPC Link -> Private Network Load Balancer -> Neptune.

It is similar to the one mentioned below (for RDS). https://aws.amazon.com/blogs/database/access-amazon-rds-across-vpcs-using-aws-privatelink-and-network-load-balancer/

But I get the message : {"message":"Service Unavailable"}.

Security groups : Neptune SG allows ingress on 8182 from SG of NLB

Target group : on TCP 8182 (shows 1 target healthy)

API in API Gateway : route /sparql on method ANY with integration to NLB with VPC Link

Can you please suggest what can be wrong here?

Amazon Neptune is not currently a supported service using AWS PrivateLink.

  • Hello Taylor, I used VPCLink with API Gateway. Can you please guide on how to implement it (may be an alternate)? I read your comments on and seems there are options. https://stackoverflow.com/questions/72370652/how-can-an-aws-neptune-graph-be-queried-via-public-http/72370837#comment135568849_72370837 – Nisarg Aug 14 '23 at 18:54
