[keycloak-user] Could not obtain configuration from server

[Pedro Igor Silva]

What version of Keycloak are you using ? Perhaps, Keycloak v4 ?

If so, you need to make sure your keycloak-authz dependency references the
same version.

The uma-configuration discovery endpoint changed to uma2-configuration.
