I have a Kafka kraft in docker-compose inside a Ubuntu server. It works correctly in locally and I can for example, list topics:

~$ docker exec -it blopa-kafka-1 /bin/bash
I have no name!@8b166cb3a647:/$ kafka-topics.sh --bootstrap-server 127.0.0.1:9092 --list
__consumer_offsets
boton_topic
dht_topic
gps_topic
pulso_topic

The problem is when trying to connect from another computer (on the same network) with the following code:

KAFKA_BOOTSTRAP_SERVERS = os.getenv('KAFKA_BOOTSTRAP_SERVERS', '192.168.1.211:9092')
app = FastAPI()

def ckeck_conectivity_kafka(kafka_bootstrap_servers):
    kafka_host, kafka_port = kafka_bootstrap_servers.split(':')
    try:

        with socket.create_connection((kafka_host, int(kafka_port)), timeout=10) as sock:

    except Exception as e:
        error_message = f"[ERROR datos_kafka] Not conection {kafka_bootstrap_servers}: {e}"
        logger.error(error_message))

check_conectivity_kafka(KAFKA_BOOTSTRAP_SERVERS)

@asynccontextmanager
async def lifespan(app: FastAPI):
    global producer
    try:
        
        producer = AIOKafkaProducer(
            bootstrap_servers=KAFKA_BOOTSTRAP_SERVERS
        )
        await producer.start()

    except Exception as e:

        await asyncio.sleep(5) 
        yield 
        return 
    yield 
...
    
app.router.lifespan_context = lifespan

This is the trace I get when I run it the code:

INFO:     Started server process [135789]
INFO:     Waiting for application startup.

ERROR:aiokafka:Unable connect to node with id 0: [Errno -2] Name or service not known
KafkaConnectionError: No connection to node with id 0

INFO:     Application startup complete.
INFO:     Uvicorn running on http://127.0.0.1:8001 (Press CTRL+C to quit)

That is, it does not throw an error, the connection is made but there are problems with the name of service.

This is my .yaml:

services:
  kafka:
    image: 'bitnami/kafka:latest'
    environment:
      - KAFKA_CFG_NODE_ID=0
      - KAFKA_CFG_PROCESS_ROLES=controller,broker
      - KAFKA_CFG_LISTENERS=PLAINTEXT://0.0.0.0:9092,CONTROLLER://:9093
      - KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CONTROLLER:PLAINTEXT,PLAINTEXT>
      - KAFKA_CFG_CONTROLLER_QUORUM_VOTERS=0@kafka:9093
      - KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER
      - KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://192.168.1.211:9092
    volumes:
      - kafka-data:/bitnami/kafka/data
    tty: true
    restart: always
    ports:
      - "9092:9092"
      - "9093:9093"
      - "9094:9094"
volumes:
    kafka-data:
      driver: local

I have been able to connect with
telnet to 192.168.1.211:9092 or nc:

nc -zv 192.168.1.211 9092
  192.168.1.211: inverse host lookup failed: Unknown host
  (UNKNOWN) [192.168.1.211] 9092 (?) open

It does not know the service or the host but the port is open
but I imagine that some problem in the configuration prevents my code from working.
