dubbo -admin 无法注册到nacos

[wolfewf]

Environment

• Dubbo Admin version: 0.4.0
• Java version: 1.8.0_301
• nacos server version: 2.0.3

Steps to reproduce this issue

1. dubbo-admin-server模块使用的nacos-client版本是2.0.2，启动时无法注册到nacos，把nacos-client版本升级到2.0.3还是没办法注册，改成1.4.2版本就可以成功注册上去

你是说将 dubbo-admin 注册到 nacos 吗？我本地测试无论是 dubbo-admin 本身注册到 nacos 还是 dubbo-admin 监听 nacos 上的服务都是可以的。检查一下是否有错误日志呢?

错误日志就是nacos无法连接，换了nacos-client版本就可以了

nacos开启用户名密码验证后就连不上了，提示认证失败
