Удаленная отладка python на vscode получила ETIMEDOUT

Question

Привет, я хочу отладить django на удаленном docker сервере. Вот моя попытка:

version: '3'    
services:
  db:
    image: postgres
    environment:
      - POSTGRES_DB=postgres
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
  web:
    build: .
    command: python manage.py runserver --noreload  0.0.0.0:8000 
    volumes:
      - .:/code
    ports:
      - "8000:8000"
      - "9000:9000"
    environment:
      - DJANGO_DEBUG=1
    depends_on:
      - db

Dockerfile

FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt

            "pathMappings": [
                {
                    "localRoot": "${workspaceFolder}",
                    "remoteRoot": "/code"
                }
            ],
            "port": 9000,
            "host": "192.168.1.15"
        }
    ]
}

            "pathMappings": [
                {
                    "localRoot": "${workspaceFolder}",
                    "remoteRoot": "/code"
                }
            ],
            "port": 9000,
            "host": "192.168.1.15"
        }
    ]
}

Ожидаемый : попадание в точку останова.

Фактически произошло : ETIMEDOUT 192.168.1.15 9000

Я действительно могу lnet 192.168.1.15 9000 с результатом:

Content-Length: 130

    {"type": "event", "seq": 0, "event": "output", "body": {"category": "telemetry", "output": "ptvsd", "data": {"version": "4.3.2"}}}

Если я посетил 192.168.1.15:9000 с браузером, я получил

Я не в курсе. Я пробовал разные версии ptvsd без удачи. Я провел часы Google безрезультатно
