org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:8888/user-microservice/default": Connection refused

My user-service config client failed to load configuration from config-service. Initially, I thought the issue was with the config-service, but when I tested it using curl http://localhost:8888/user-microservice/default, it successfully returned data. The problem only occurs when using Docker Compose, whereas everything works fine when running directly in the IDE. Could you provide some insights to help resolve this?

Also, the configurations for both user-service and book-service are stored in a remote repository accessible from config-service server.

That's docker-compose.file:

version: "3.9"
services:
  config-service:
    build: ./ConfigServer
    container_name: config-service
    ports:
      - "8888:8888"
    environment:
      - GIT_USERNAME=${GIT_USERNAME}
      - GIT_PASSWORD=${GIT_PASSWORD}
    networks:
      - library-network

  discovery-service:
    build: ./EurekaServer
    container_name: discovery-service
    ports:
      - "8761:8761"
    depends_on:
      - config-service
    networks:
      - library-network

  gateway-service:
    build: ./API_Gateway
    container_name: gateway-service
    ports:
      - "8090:8090"
    depends_on:
      - discovery-service
    networks:
      - library-network

  user-service:
    build: ./user-microservice
    container_name: user-service
    ports:
      - "8081:8081"
    depends_on:
      - discovery-service
      - config-service
    networks:
      - library-network

  book-service:
    build: ./book-microservice
    container_name: book-service
    ports:
      - "8082:8082"
    depends_on:
      - discovery-service
    networks:
      - library-network

networks:
  library-network:
    driver: bridge

Start with the docker-compose configuration shown in the issue, especially the config-service and user-service entries, and compare how the configuration client reaches the server in Docker versus the IDE. Reproduce the failure with Docker Compose and verify that user-service loads its remote configuration without a connection-refused error.
