请提供 controller 日志、服务列表截图、controller 的运行时配置（注意脱敏）。

参考文档：

Please provide controller logs, service list screenshots, and controller runtime configuration (note desensitization).

@Erica177 configz 里有基于 Nacos 生成的WasmPlugin 配置但没有 ServiceEntry 等配置。可能是什么原因呢？

通过controller的日志观察是mcpserver订阅的服务没有返回实例节点，

controller.log

mcpserver引用的nacos服务是健康且有实例的吗，另外麻烦提供一下nacos sdk的日志，在controller的/var/log/nacos/log/mcp/log目录下

我换成ip就可以了，应该是容器里面无法解析域名。感谢各位老师的帮助

logan2013

应该是容器里面无法解析域名

这里配域名应该也是允许的吧。 @Erica177 怎么看？

CH3CHO

nacos服务的地址可以是dns，他的意思可能是nacos实例没有办法通过域名解析出来服务的ip

Erica177

确认没有问题，可以先关掉这个issue，后续有问题欢迎继续交流～
