Настройка keycloak и Spring

Произвожу настройки. Но при переходе по localhost:8080/api/admin Выдает ошибку:

Мой код application.yml

` keycloak:
auth-server-url: http://localhost:8484/auth
realm: Master
resource: my_client
public-client: true
#use-resource-role-mappings: true`

Настройки application.properties

keycloak.realm=Master

keycloak.resource=my_client

keycloak.public-client=true

keycloak.principal-attribute=preferred_username
