I successfully setup RabbitMQ cluster by helm usig this chart (https://github.com/helm/charts/tree/master/stable/rabbitmq-ha) in k8s, but can't create connection with server in my exteranl .net core application. Receiving such exception:

RabbitMQ.Client.Exceptions.BrokerUnreachableException: "None of the specified endpoints were reachable

I have enabled ingress and have access to rmq managment console with hostname. I checked ports(5672, 15672) in docker containers, they are opened. What is wrong with this?
