[BUG] <StatusCode 404 reported when connecting to nacos2.0.3 version container>

[Tanwencheng]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

1.拉取master分支的源代码，本地代码方式部署启动后，配置nacos注册配置中心时，显示测试连接失败StatusCode 404，后更换为镜像的app-nacos.yml 配置文件，可正常使用，希望找出问题原因

2.源代码app-nacos.yml配置

Hi, I found that this bug is caused by differences between versions of nacos api.
And it has been fixed. #880
