Unable to port-forward to temporal pod deployed in the k8s cluster

in the k8s cluster i’ve a running pod which is temporal service (1 instance) everything configured and connected properly (postgres, web-ui ) even runned a hello world example just to confirm everything is correct and all worked.
But im unable to port-forward directly to pod and run with tctl the commands.

> kubectl port-forward temporal-7469d47869-wxq6z 7233:7233

Error Details: rpc error: code = Unavailable desc = connection closed
('export TEMPORAL_CLI_SHOW_STACKS=1' to see stack traces)

Questions:
What do i need to configure to allow it to accept connections?
Where should i bind the server ?

Thank you for your time.
