com.alibaba.nacos.api.exception.NacosException: failed to req API:/nacos/v1/ns/instance after all servers([localhost:8848]) tried: java.net.ConnectException: Connection refused (Connection refused) at

nacos启动了，ip：8848 nacos主页也没有问题

nacos依赖引入了

nacos配置：boostrap.yml

server:
  port: 3002
spring:
  application:
    name: static-service
  cloud:
    nacos:
      server-addr: 192.168.31.166:8848

原来是server-addr 当时打错了，当时写成server-add，耻辱柱啊

server-addr: 192.168.31.166:8848
