I exposed service Kong Manager with NodePort
Howerver, when I access to portal, I can not use portal to: Add service, route, …
Why? Please help me!
Thank you!

@Shadow - I assume you have enterprise: enabled in your values.yml

Click on a workspace (default) and you will be able to add routes etc.,

Also add the two env entries which is same URL you are trying to access in browser,

admin_api_uri: “http://localhost:8001
admin_gui_url: “http://localhost:8002

It looks like kind of whitelisting, even if I use in browser it does not display the manager page.
