Hello!
Is your Kogito application secured (does it require a token from an Identity Provider)?
The Management Console will always make requests to
/q/oidc/.well-known/openid-configuration, but it fails silently if that endpoint is not found and assumes that your Kogito app is not secured. So that's probably not the issue.
Can you check the browser console for more error messages? It's possible that Management Console requests are being blocked by CORS.
