<!-- 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. ## Ask your question here consumer配置指定dubbo端口是7001，provider配置指定的dubbo端口是5001，<br> 但是建立连接时却是：The connection of /192.168.0.109:**51490** -> /192.168.0.109:5001 is established，<br> 导致调用接口时报No provider异常。 其中这个5位数的端口不是配置指定的，而且每次重启会改变。 - Dubbo version: 2.7.8 - Java version: 1.8 服务启动顺序：先启动consumer，再启动provider。 provider启动完成时**consumer**打出来的日志： ```log 2023-03-02 00:35:55.615 INFO 20228 --- [ncesChangeEvent] a.DubboServiceDiscoveryAutoConfiguration : The event of the service instances[name : ds-service , size : 1] change is about to be dispatched 2023-03-02 00:35:55.616 WARN 20228 --- [ncesChangeEvent] c.a.c.dubbo.registry.DubboCloudRegistry : APP ds-service instance changed, size changed zero!!!
