Kong Manager with https not showing Workspace

When viewing in http everything is working fine. Default workspace shows and no errors. But when calling Kong Manager w/ https, no Default workspace is showing and the “create workspace” button is inactive.

Any one managed to get this to work on the free-mode (open source) version? Or is this feature not supported?

Could you pls share the reference link and configurations you followed to bring up kong manager in free mode…
And are you able to create services/routes via the manager UI ?
Because i am not able to load the manager UI and everything is greyed out.
