1.以上框住的服务和服务提供者都是在调试的时候产生的，均已停止项目已停机，但是在dubbo-admin里面并未删除（或者说是zookeeper未删除？），zookeeper的安装配置使用了https://dubbo.incubator.apache.org/zh-cn/docs/admin/install/zookeeper.html的配置

2. 消费方启动程序@reference里面不指定url，启动时会尝试去连接127.0.0.1和192.168.1.49这两个已停止的提供方，然后出现拒绝连接的报错
3. xxx

Pls. provide [GitHub address] to reproduce this issue.

应该自动删除已停机服务，消费方启动时不该再去连接已停止的服务

请问这种情况要怎么解决啊？还是设置错了？

[carryxyh]

#3785
应该和这个是相同的问题。

[Hmilyhyun]

所以我是自己打包一下还是等bugfix啊？

[carryxyh]

如果等bugfix成本比较高的话，只能自己打包了。

[cvictory]

@carryxyh How is it going now?

[bruce-qin]

还原到2.7.0吧 2.7.1有这个问题

[Hmilyhyun]

@bruce-qin 2.7.0因为两层代理问题提供方没办法抛出原始异常，会变成未声明异常~
