Issues with axoniq server API connectivity on AWS

Axon Framework
,
1

Hi Team,
We are using AxonServer-2023.1.0 in SE mode.
We are trying to deploy our services on AWS.
We have hosted the axon server on Windows EC2 machine and initialized it with default context and SE mode.
We are able to access this server’s Rest API as well as management UI URLS from public internet.
But we are facing challenge while connecting to the Rest API from our springboot app deployed into same VPC.
The spring boot app is deployed in server less mode using AWS App Runner service.
Please let us know if there is any documentation for deployment pattern for Axoniq server on AWS.
We keep getting below error:

It’s not a Rest API, but a gRPC API, possibly you need some additional configuration, because gRPC goes uses HTTP/2 as transport medium?

Hey Shrirang,
I notice the following log message:

Do you have the Axon Server hostname specified using the axon.axonserver.servers property? Could it be this value is set to empty? That would explain the missing hostname/FQDN.

Hi All, the issue got resolved. We were providing hostname property but provided public IP of the windows EC2 where Axon Server was running. The issue got fixed when we provided private IP as both of the services running in same VPC.
