HCP Vault Kubernetes Configuration

Kubernetes auth configuration is not showing up in UI under
Access - Auth Methods - Kubernetes - Edit Configuration

While trying to view Kubernetes auth for HCP Vault under UI following error pops up:

Sorry, we were unable to find any content at `/v1/auth/kubernetes/config?help=1` .
Double-check the URL or go back home.

Kubernetes configuration works from CLI as I’m configuring it over CLI.

Note: This Vault cluster has enabled public access and is used over public URL.
