Экземпляр микросервиса Spring не регистрируется в Eureka, работающем на порту, отличном от 8761

application.yml моего микросервиса (клиент для Эврики)

spring:
  application:
    name: queue1

eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true  
    serviceUrl:
      defaultZone: http://localhost:8762/

server:
  port: 7777

app:
  id: ${random.uuid}

application.yml Эврики

eureka:
  instance:
    hostname: peer1
  client:
    register-with-eureka: false
    fetch-registry: false
server:
  port: 8762

Я запускаю Eureka с порта 8762 и ссылаюсь на это в своих микросервисах. Микросервис не может зарегистрироваться в Eureka. Ниже приведены исключения из журналов микросервисов.

Теперь самое главное, все будет отлично, если я изменю порт сервера Eureka и порт регистрации Eureka микросервиса на 8761 !!!! Регистрация микросервиса в этом случае проходит успешно.

Делал это несколько раз, прежде чем опубликовать вопрос, и он ведет себя так.

Любые входные данные здесь были бы очень полезны.
