最近在学习 Go-Micro 框架，参考的是 <https://studygolang.com/articles/23208?fr=sidebar> 这篇文章。
在测试服务编写完成后，开启 Micro 服务输出内容如下：
```shell

```
可以看到授权似乎出现了问题，但其它日志输出正常
```shell
2020-08-04 16:58:40 file=server/rpc_server.go:840 level=info service=server Broker [tunnel] Connected to [::]:8085
{"id":"go.micro.client","code":500,"detail":"service go.micro.auth: not found","status":"Internal Server Error"}

{"id":"go.micro.client","code":500,"detail":"service go.micro.auth: not found","status":"Internal Server Error"}
```
接着我使用了试着输出服务列表，输出以下错误：
```shell
>micro list services
{"id":"go.micro.client","code":500,"detail":"connection error: desc = \"transport: Error while dialing dial tcp 127.0.0.1:8081: connectex: No connection could be made because the target machine actively refused it.\"","status":"Inte
rnal Server Error"}
```
按照它说的我去防火墙添加了**8081**端口的出入站规则，但还是输出同样的错误，所以想请教下各位这个问题需要如何解决？
这个问题看起来是好久以前的了，我们现在用go-micro 2.X版本，也有类似的问题我贴一下代码 ，哪位大佬能看出什么问题来
