pulpito-ng.ceph.com doesn't appear to work without vpn

I visited https://pulpito-ng.ceph.com/ without being on the Ceph Sepia Lab VPN.
The result was a "spinner" icon and there was not obvious error it just sat there making no progress.
I looked at the webdev console and saw it was trying to access, and fail, urls like https://paddles.front.sepia.ceph.com/runs/?page=1

Based on this I figured that this frontend relies on backend services that only are available when logged into the Sepia Lab VPN. A couple thoughts:

1. Don't expose pulpito-ng.ceph.com to the public internet - require the VPN
2. Show an error that says "You need the Sepia Lab VPN" if many api requests fail
3. Enable a mode for it to work fully without the VPN

Thanks!
