I have docker container running in localhost. And inside this container I have created one python script to access one endpoint which is from another server. After executing docker-compose exec server bash command, I will be inside the container. I could not access this endpoint inside the container. When I try curl command to check, it returns connection timed out error.

For the same endpoint, if I try it anywhere outside container, it works.

version: "3.2"
services:
  server:
    image: image1
    build: ./docker/
    environment:
      L_PASSWORD: "password"
      L_LICENSE_FILE: "/opt/l7esp/project/conf/esp.license"
    ports:
      - published: 8002
        target: 8002
        protocol: tcp
        mode: host
      - published: 8003
        target: 1487
        protocol: tcp
        mode: host
    volumes:
      - type: bind
        source: .
        target: /opt/l/project
      - type: volume
        source: data
        target: /opt/l/data
      - type: volume
        source: static
        target: /opt/l/server/lib/www/static
volumes:
  data: {}
  static: {}

This is the docker-compose.yml file that I am using. Is this anything needs to be done so that I can access the external endpoint inside the docker container?
Has anyone gone through the similar issues and resolved? Kindly guide me
