• Diagnostic report throws below error :

ERROR: [DCli0013 from diagnostic ConfigContexts@openshift/origin/pkg/diagnostics/client/config_contexts.go:285]
       For client config context 'privategithub/master.example.com:8443/<user>':
       The server URL is 'https://master.example.com :8443'
       The user authentication is 'master.example.com:8443'
       The current project is 'privategithub'
       (*errors.StatusError) User "system:anonymous" cannot list all projects in the cluster

       This means that when we tried to make a request to the master API
       server, your kubeconfig did not present valid credentials to
       authenticate your client. Credentials generally consist of a client
       key/certificate or an access token. Your kubeconfig may not have
       presented any, or they may be invalid.
