原因

我也是百度了之后才知道。
这个错误是我们使用nacos2.0之后才有的，因为nacos2.0需要开放两个8848（nacos服务端口）偏移后的端口，
官网的解释:
https://nacos.io/zh-cn/docs/2.0.0-compatibility.html

而我们的配置：
原来报错的配置

spring:application:#  服务名称name: luoshen-gatewayprofiles:#  配置文件选择active: devcloud:nacos:config:#服务器地址server-addr: 127.0.0.1:8868# 配置文件格式file-extension: yml# 共享配置shared-configs:- application-${spring.profiles.active}.${spring.cloud.nacos.config.file-extension}

修改后的配置：

# Spring
spring:application:#  服务名称name: luoshen-gatewayprofiles:#  配置文件选择active: devcloud:nacos:discovery:server-addr: 127.0.0.1:8868config:#服务器地址server-addr: 127.0.0.1:8868# 配置文件格式file-extension: ymlshared-configs:- application-${spring.profiles.active}.${spring.cloud.nacos.config.file-extension}

我们发现多加了一个nacos地址，这个就是告诉服务如何连接那两个偏移的端口。
