Kubernetes dashboard GUI not coming, else i get json format

#1

Unable to get the GUI of dashboard, inspite the cluster is up and running.
I am able to login to the first kubernetes login prompt, but the output of that is a json file and not the UI of kubernetes, I used the same dashboard version below https://github.com/kubernetes/dashboard

Anyone please suggest. I have run out all google links to find a solution :frowning:
