When i dispatch a message in the handler i have this error:
Could not connect to the AMQP server. Please verify the provided DSN. ({\"host\":\"localhost\",\"port\":5672,\"vhost\":\"\\/\",\"login\":\"guest\",\"password\":\"********\"}

messenger.yml
framework:
    messenger:
        # Uncomment this (and the failed transport below) to send failed messages to this transport for later handling.
        # failure_transport: failed

        transports:
            # https://symfony.com/doc/current/messenger.html#transport-configuration
            amqp: "%env(MESSENGER_TRANSPORT_DSN)%"
            # failed: 'doctrine://default?queue_name=failed'
            # sync: 'sync://'

        routing:
            # Route your messages to the transports

I just add rabitmq image in my docker-compose file and add an user given them admin permissions to permit him to have access to the host.

rabbitmq:
    image: bitnami/rabbitmq:latest
    container_name: rabbitmq
    volumes:
      - ./rabbitmq-persistence:/bitnami
    ports:
      - 15672:15672

and I use in .env file

MESSENGER_TRANSPORT_DSN=amqp://username:password@rabbitmq:5672/%2f/messages

You not pass in docker-compose a port 5672 IMHO. So you can't connect.

Edit: The Exception with message: Could not connect to the AMQP server. Please verify the provided DSN was thrown in \Symfony\Component\Messenger\Transport\AmqpExt\Connection:387 with super exception from amqp-extension which definitely indicates no connection, not a Symfony error.
