### 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 version: 3.3.0 openjdk:17-jdk-alpine Registry: ZooKeeper Orchestration: Kubernetes Network: Full connectivity between K8S cluster and ZooKeeper ### Steps to reproduce this issue - Deploy Dubbo provider services in K8S cluster, registered to external ZooKeeper. - Deploy Dubbo consumer services in the same K8S cluster, consuming the provider services. - Verify that service discovery works correctly and consumers can connect to providers. - Trigger a redeployment of the provider services in K8S (e.g., rolling update). - Observe that ZooKeeper registry updates with new provider addresses. - Notice that consumers continue attempting to connect to old provider addresses, resulting in connection failures. ### What you expected to happen When providers are redeployed in K8S and their addresses change in ZooKeeper, consumers should: Receive offline notifications for old providers. Update their provider address caches. Establish connections to new providers without errors. ### Anything else We are using Dubbo 3.3.0 in a Kubernetes cluster with an external ZooKeeper registry. The network connectivity between the K8S cluster and ZooKeeper is working properly. However, we are encountering an issue where after redeploying provider services in K8S, the ZooKeeper registry correctly updates the provider list, but the consumers inside the K8S cluster fail to receive the offline notifications for the old providers. This results in connection failures with error messages like "Failed to connect to server". ### Are you willing to submit a pull request to fix on your own? - [ ] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
