Почему Openshift не может получить доступ к API метрик, но метрики настроены?

Я пытаюсь настроить автоматическое масштабирование на openshift OKD. Я использую Openshift 3.11.

Итак, я установил метрики и метрики Hawkular, установил URL-адрес и установил файлы хоста, указывающие на него.

Получение HorizontalPodAutoscaler:

oc describe hpa

Таким образом, он не может получить доступ к Metrics API.

Кроме того, получение метрик APIProxy дает:

oc adm diagnostics MetricsApiProxy

Дает:
