一、该问题的重现步骤是什么?
1. 注册中心的地址进行修改
2. 报错 failed to req API:127.0.0.1:8848/nacos/v1/ns/instance. code:500 msg: java.net.ConnectException: 拒绝连接 (Connection refused)
3.
二、你期待的结果是什么?实际看到的又是什么?
接口可以启动成功,报错 failed to req API:127.0.0.1:8848/nacos/v1/ns/instance. code:500 msg: java.net.ConnectException: 拒绝连接 (Connection refused)
三、你正在使用的是什么产品,什么版本?在什么操作系统上?
四、请提供详细的错误堆栈信息,这很重要。
