Launch kubectl failed after upgrade to 2.0.8

Hey all, first of all, forgive my english if there is any mistakes…

I’ve been using rancher 2.0.2 for about four months, and decided to upgrade to version 2.0.8. However, when I click Lauch Kubectl from Rancher GUI there is only this:

I’ve been roaming the google and trying to find the solution, but came up empty…

My suspicion is that the .kube/config file in rancher is not correct, because the certificate-authority-data part in the config provided from Rancher GUI is alot shorter from the config file in my workstation. Is there any way to modify the config file in rancher server to fix this problem? or is this is not the problem that making my web kubectl broken?

Any help really appreciated. Many thanks…

I have same issue in local Rancher 2 cluster. It just stopped working. I did not upgrade it.

yeah, in the end, I use kubectl natively in my workstation. Hopefully there will be some way to fix this
