我通过在k8s中使用此图表（https://github.com/helm/charts/tree/master/stable/rabbitmq-ha）成功地设置了RabbitMQ群集，但是无法在exteranl .net核心应用程序中与服务器建立连接。收到此类异常：
RabbitMQ.Client.Exceptions.BrokerUnreachableException: "None of the specified endpoints were reachable
我已启用入口并可以使用主机名访问rmq管理控制台。我检查了Docker容器中的端口（5672，15672），它们已打开。怎么了？
