I’m trying to set up a RabbitMQ instance using Docker, but I’m having trouble connecting to it from another service within the same Docker Compose network. Here’s what I have so far:

Docker Compose File:

version: '3.8'

services:
  rabbitmq:
    image: rabbitmq:3-management
    container_name: rabbitmq
    ports:
      - "5672:5672"
      - "15672:15672"
    networks:
      - my-network

  server:
    build:
      context: ./Server
    ports:
      - "5000:5000"
    networks:
      - my-network
    depends_on:
      - rabbitmq

  worker:
    build:
      context: ./workers
    container_name: python_worker
    environment:
      RABBITMQ_URL: amqp://localhost:5672
    networks:
      - my-network
    depends_on:
      - rabbitmq

networks:
  my-network:
    driver: bridge

I can access the RabbitMQ management interface at http://localhost:15672, but my my-service application can’t connect to RabbitMQ using the RABBITMQ_URL: amqp://rabbitmq:5672.
The error message I receive is: Error: Unable to connect to RabbitMQ server.
What I’ve Tried:

Verified that both services are on the same Docker network (my-network).
Ensured that the RABBITMQ_URL in my-service is set to amqp://rabbitmq:5672, which should be the correct internal URL.
Checked the RabbitMQ logs, but didn’t find anything helpful.
Questions:

What might be causing the connection issue between my service and RabbitMQ within Docker?
Are there any additional steps I should take to debug or configure the network settings?
Any help or insights would be greatly appreciated!
