Axon Server connection issue – "UNAVAILABLE: io exception" when starting client

Architectural Concepts

Hi everyone, :blush:
I’m facing a connection issue between my Axon Framework application and Axon Server. When I try to start the client service, I get the following error:

UNAVAILABLE: io exception
Caused by: io.grpc.netty.shaded.io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused

Recently I completed power bi course in hyderabad and I’ve confirmed that Axon Server is running on the correct port (8124), and I can access the Axon dashboard in the browser. The axon.server.servers property is correctly set in application.yml.

I also check this :[Axon Server migration] Exception when starting the migration processs : Large Objects may not be used in auto-commit mode. Could this be a TLS/misconfiguration issue or something network-related? Any guidance on how to troubleshoot or fix this would be greatly appreciated.

Thanks in advance!
