docker 部署nacos集群到mysql数据库的问题

问题遇到的现象和发生背景

docker 部署nacos集群到mysql数据库，外面使用的是nginx来做统一入口，nacos配置管理没有问题，但是服务注册于发现出现code:503 msg: server is DOWNnow, detailed error message: Optional[Distro protocol is not initialized
配置管理正常使用：

服务管理出现以下问题：

问题相关代码，请勿粘贴截图

以下是IDEA配置文件：
server:
port: 9002
spring:
application:
name: nacos-payment-provider
cloud:
nacos:
discovery:
server-addr: 192.168.0.103:2124 #nginx的访问路径
management:
endpoints:
web:
exposure:
include: '*'

运行结果及报错内容

使用idea客户端向nacos服务注册时报：
java.lang.IllegalStateException: failed to req API:/nacos/v1/ns/instance after all servers([192.168.0.103:2124]) tried: failed to req API:192.168.0.103:2124/nacos/v1/ns/instance. code:503 msg: server is DOWNnow, detailed error message: Optional[Distro protocol is not initialized]

我的解答思路和尝试过的方法

删除nacos下的data文件夹

我想要达到的结果

可以成功注册到nacos集群上不是单机模式并将数据存储到MySQL数据库中

你试试编码问题，我之前碰到过。指定项目启动的编码为UTF-8
