Hi,I’m using Rancher-V2.2.5(Mac osx)  
1.Copy kubconfig file from Rancher cluster page to ~/.kube/config.  
2.When I run `kubectl version `,returns “Unable to connect to the server: x509: certificate signed by unknown authority”.  
But,When I run `sudo kubectl version`, It works ok.

When I login with root in the shell,run with command `kubectl version `,still returns “Unable to connect to the server: x509: certificate signed by unknown authority”.  
I’m confused,what’s happend?Pls help me,Tks!
