I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository. There is a similar issue #10198. I did as the issue described, but still failed.

### Environment

* Dubbo version: branch 3.1
* Operating System version: win7
* Java version: 11

### Steps to reproduce this issue

1. modify the dubbo.properties in [dubbo-demo-xml-provider](https://github.com/apache/dubbo/tree/3.1/dubbo-demo/dubbo-demo-xml/dubbo-demo-xml-provider)
`dubbo.application.qos-enable=true`
`dubbo.application.qos-port=33333`
`dubbo.application.qos-accept-foreign-ip=true`
2. run dubbo-demo-xml-provider

### Expected Behavior

`telnet {ip} 33333` will connect to QoS server successfully.

### Actual Behavior

There is no exception. Provider is successfully started and running.
