Login via KeyRock returns error

Hi,

I am trying to login via KeyRock in Draco, but after configuring the app in KeyRock and adding the corresponding properties in Draco's config file.

Upon entering the Draco interface, I am redirected to keyRock and logged in. Then it redirects to the draco again and I get this error:

2022-06-23 06:42:32,651 ERROR [NiFi Web Server-79] o.apache.nifi.web.api.OIDCAccessResource Unable to exchange authorization for ID token: Connection refused (Connection refused)

What I can be doing wrong?

Thanks!
