<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy --> - [ x ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.0.5 * Operating System version: k8s/spring boot * Java version: jdk11 ### Steps to reproduce this issue 1. 在配置文件`application.yml`中开启探针 ```yaml dubbo: application: name: demo-provider qos-enable: true qos-accept-foreign-ip: true ``` 2. 启动应用，此时consumer可以正常调用provider，可以正常返回结果。 3. 但是，访问以下三个地址 ```bash curl -v http://localhost:22222/live # 返回true curl -v http://localhost:22222/ready # 报错 curl -v http://localhost:22222/startup #报错 ``` 访问http://localhost:22222/ready 异常信息如下： ``` 2022-01-27 12:20:58.515 ERROR
