When I use RabbitMQ from localhost, I supply my RabbitMQConnectionString as localhost in my ASP.NET Core WebApi and everything works fine.

But I wanted to use RabbitMQ from a Kubernetes Cluster, so, I created a new Namespace in Kubernetes Cluster for RabbitMQ, then I created an app from the Kubernetes Dashboard with the image: rabbitmq:management I specified External Service with Port and target Port as 15672 for both. And waited for it to be deployed.

I can access the management portal of RabbitMQ with the External IP of service: xx.xx.153.133:15672 in the browser, but When I use this IP with port as RabbitMQConnectionString in my ASP.NET Core WebApi, it gives me the following error(through seq):

And when I supply IP only i.e. xx.xx.153.133, it searches RabbitMQ on 5672 instead of 15672 and gives me the following error:

Can someone please guide me through on how to proceed and fix the error.
