I try to start dubbo-samples-annotation project, but failed.

First, I start AnnotationProviderBootstrap , that is ok.
and output log :

[24/02/23 12:38:13:013 CST] main  INFO server.Server:  [DUBBO] qos-server bind localhost:22222, dubbo version: 3.2.0-beta.5-SNAPSHOT, current host: 192.168.31.232

And then, I try to start AnnotationConsumerBootstrap , it's failed! The output log below:

[24/02/23 12:51:28:028 CST] DubboShutdownHook  WARN integration.RegistryProtocol:  [DUBBO] null, dubbo version: 3.2.0-beta.5-SNAPSHOT, current host: 192.168.31.232, error code: 99-0.

You can remove

System.out.println("greeting : " + annotationAction.doGreeting("world"));
  System.out.println("reply : " + annotationAction.replyGreeting("world"));

in AnnotationConsumerBootstrap .
it will always time out

This is a log when shutting down.
