Describe the Bug
Our scenario is to persist nacos data in mysql.
We deployed nacos serivce and mysql service, and mysql is used as nacos storage db.
It ran normally for the first few times. After restarting the kubesphere cluster, nacos connected to mysql timed out.
For abnormal messages, please refer to the following screenshot

Versions Used
KubeSphere: v3.4.1
Kubernetes: v1.26.14

Environment
How many nodes and their hardware configuration:
CentOS 7.9 / 1 masters: 4cpu/10g; 2 nodes: 4cpu/16g

Please tell me whether it is a problem with DNS resolution or a problem with network connection. How to solve this problem?
Very urgent, please help
Expected behavior
all service ok

使用nacos-operator快速启动一个就不会错了，参考 https://nacos.io/zh-cn/docs/quickstart/quick-start-kubernetes/

这其实并不是ks的问题，是nacos的问题

这里dns解析不成功，internal ip可以连接，这里dns不是kubesphere生成？目前我这里重新安装了一个kubershere集群,新集群没有出现这个问题，老集群问题依然存在
