Невозможно подключиться к командному метрическому потоку. в Eureka Admin

Question

Я получаю сообщение об ошибке ниже - Невозможно подключиться к командному метрическому потоку.

Я реализовал api-gateway-service из https://howtodoinjava.com/spring-cloud/microservices-monitoring/, используя загрузочную версию 2.1.2.RELEASE и облачная версия Greenwich.RC2 .
