¿Por qué veo errores de SyncLoadBalancerFailed al crear un clúster de VPC?

Al configurar el equilibrio de carga en mi clúster de VPC, veo un mensaje de error similar al siguiente.

Warning  CreatingCloudLoadBalancerFailed  55s                ibm-cloud-provider  Error on cloud load balancer kube-<CLUSTERID>-<SERVICE_UUID> for service <NAMESPACE>/<SERVICE_NAME> with UID <SERVICE_UUID>: Failed ensuring LoadBalancer: FindLoadBalancer failed: FindLoadBalancer failed: An error occurred while performing the 'authenticate' step: 400 Bad Request [{"incidentID":"XXX","code":"XXX","description":"Error message from IAM: '401 Unauthorized.

Este error se produce cuando la lista de elementos permitidos de IAM no permite la comunicación necesaria con las IP de panel de control.

Para resolver este problema, añada las IP de panel de control para la región en la que se encuentra el clúster en la lista de elementos permitidos de IAM.

Para obtener una lista de IP de plano de control por región, consulte el IBM/kube-samples repositorio de
