### Pre-check - [X] I am sure that all the content I provide is in English. ### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version Dubbo Java 3.2.9， OracleJDK 1.8，centos7，Dubbo register：阿里云MSE（nacos 2.1.2.0）Dubbo register mode：instance ### Steps to reproduce this issue 1. Change the provider application name (e.g., dubbo.application.name from patient-service-provider to distinct-patient-service). 2. Restart one provider instance (e.g., 10.0.18.9), and the consumer cannot subscribe normally. 3. Restart all provider instances, and the consumer reports "no provider available." ### What you expected to happen The consumer subscribes normally ### Anything else Some consumer logs show that the restarted instance (10.0.18.9) cannot be added to the invokers. class:o.a.d.r.c.directory.AbstractDirectory level:INFO message: [DUBBO] The invoker DefaultServiceInstance{serviceName='patient-service-provider', host='10.0.18.9', port=21350, enabled=true, healthy=true, metadata={dubbo.metadata-service.url-params={"serialization":"hessian2","prefer.serialization":"hessian2","version":"1.0.0","dubbo":"2.0.2","release":"3.2.9","side":"provider","port":"21350","protocol":"dubbo"}, dubbo.endpoints=[{"port":21350,"protocol":"dubbo"}], dubbo.metadata.revision=60a6cb6dc32ee581ff3f6d4eedea2283, dubbo.metadata.storage-type=local, timestamp=1725285283509}}, service{name='com.distinct.patient.api.PatientApi',group='null',version='1.0.0',protocol='dubbo',port='21350',params={side=provider, release=3.2.9, methods=createPatentdeprecated=false, dubbo=2.0.2, interface=com.distinct.patient.api.PatientApi, service-name-mapping=true, version=1.0.0, timeout=30000, generic=false, revision=1.0.0, serialize.check.status=WARN, serialization=hessian2, application=patient-service-provider, prefer.serialization=hessian2, dyna mic=true, REGISTRY_CLUSTER=nacos-registry},} has been added to invalidate list due to connectivity problem.
