com.alibaba.nacos.api.exception.NacosException

具体异常如下：

com.alibaba.nacos.api.exception.NacosException: <html><body><h1>Whitelabel Error Page</h1><p>This application has no explicit mapping for /error, so you are seeing this as a fallback.</p><div id='created'>Fri Apr 14 14:31:24 CST 2023</div><div>There was an unexpected error (type=Forbidden, status=403).</div><div>unknown user!</div></body></html>

经排查，原因是本地指定了命名空间但是对应的nacos 的 discovery下未能配置用户密码导致 找不到/无法连接对应配置中心的服务

处理：指定配置命名空间，并配置用户密码授权就好了
