Unable to connect to Pulsar in Multi AKS cluster setup

@lhotari
Hello,
We have Pulsar cluster deployed across different AKS regions along with Pulsar Proxy. And when clients connect to proxy using the proxy endpoint it is not resolving to the external advertised Listener which is configured in the broker config. The error we are getting is below. Is there a specific config or parameter for this to work in a multi AKS cluster.(Single Pulsar cluster deployed acress multiple AKS clusters)
