问题描述

使用nacos下线一个节点的服务时，弹窗报错：

caused: errCode: 500, errMsg: do metadata operation failed ;caused: 
com.alibaba.nacos.consistency.exception.ConsistencyException: The Raft Group [naming_instance_metadata] did not find
 the Leader node;caused: The Raft Group [naming_instance_metadata] did not find the Leader node

解决办法

1、先停掉nacos
2、到nacos安装目录下，找到data->protocal
3、把protocal整个文件夹删了，然后重启nacos就行了
