我正在阅读入门教程linkerd，我已经stable-2.1.0安装在 kubev1.9.6和v1.12.3
我已经验证所有 pod 都在运行，并且网格正在通过仪表板工作。
当我尝试linkerd -n linkerd top deploy/linkerd-web在第 4 步中运行时，我invalid argument从控制器返回。
这是详细的输出：
DEBU[0000] Expecting API to be served over [https://xx.xx.xx.xx:6443/api/v1/namespaces/linkerd/services/linkerd-controller-api:http/proxy/api/v1/]

关于我接下来应该尝试什么的任何建议？
