listeners=KAFKARTGS://:9092,CONTROLLER://:9093
inter.broker.listener.name=KAFKARTGS
controller.listener.names=CONTROLLER
listener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL,KAFKARTGS:PLAINTEXT

what did i misconfigured?
when i set configuration like below, it works well. but, above configuration don't.
i don't understand what's difference between them.
i just changed the name of listeners. TT
listeners=PLAINTEXT://:9092,CONTROLLER://:9093
# Name of listener used for communication between brokers.
inter.broker.listener.name=PLAINTEXT
# Listener name, hostname and port the broker will advertise to clients.
# If not set, it uses the value for "listeners".
advertised.listeners=PLAINTEXT://kafka-rtgs3:9092
# A comma-separated list of the names of the listeners used by the controller.
# If no explicit mapping set in `listener.security.protocol.map`, default will be using PLAINTEXT protocol
# This is required if running in KRaft mode.
controller.listener.names=CONTROLLER
# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details
listener.security.protocol.map=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL
