Unable to connect to Datomic Cloud using VPC endpoint

Datomic cloud successfully installed on AWS and able to access it using socks proxy. Now we are trying to connect to Datomic using VPC endpoint with REPL commands from a client machine which is outside of the datomic VPC. The VPC endpoint was created by following the steps mentioned in

https://docs.datomic.com/cloud/operation/client-applications.html#create-endpoint

Here is the error that we are facing.

Execution error (ExceptionInfo) at datomic.client.impl.cloud/get-s3-auth-path (cloud.clj:178).
Unable to connect to http://:8182

The VPC endpoint security group is allowing traffic only from a particular security group. I updated the security group inbound rules to allow traffic from Client machine and now i am able to access Datomic with VPC endpoint.
