nacos 1.4.1 : dom name can only have these characters: 0-9a-zA-Z-._:, current: DEFAULT_GROUP@@nacos‐restful‐provider-xxx #5399

Describe the bug when I use springboot with nacos 1.4.1, application throws NacosException: 

failed to req API:/nacos/v1/ns/instance after all servers([http://127.0.0.1:8848]) tried: ErrCode:400, ErrMsg:caused: dom name can only have these characters: 0-9a-zA-Z-._:, current: DEFAULT_GROUP@@nacos‐restful‐provider-192.168.31.102:56010;

there are same expcetion report in issues list, but my nacos version is different from theirs. so I have no idea whether my config is wrong or the exception is not solved.

my project: https://github.com/zhanjinhao/nacos-discovery.git

version

I have checked the nacos-client version and nacos-server version, they both are 1.4.1, and spring-cloud-alibaba:2.2.5.RELEASE is compatible with springcloud:Hoxton.SR8 in alibaba's official statement. Here is their page: https://github.com/alibaba/spring-cloud-alibaba/releases/tag/2.2.5.RELEASE. nacos-server runs in standalone mode.
