Clients cannot access port 8072

When the odoo17 image uses the following configuration, the client cannot access port 8072. As a result, Nginx keeps reporting errors.How to solve this problem?

nginx err：
upstream: "http://172.17.0.1:8072/websocket?version=17.0-1"
docker-compose.yml

version: '3.1'

services:
  web:
    image: odoo:17.0
    depends_on:
      - db
    ports:
      - "8069:8069"
      - "8072:8072"
    volumes:
      - ./odoo_web_data:/var/lib/odoo
      - ./config:/etc/odoo
      - ./addons:/mnt/extra-addons
      - ./logs:/var/log/odoo
    environment:
      - ODOO_DB_PASSWORD=odoo
    restart: on-failure

  db:
    image: postgres:15.0
    ports:
      - "5432:5432"
    environment:
      - POSTGRES_DB=postgres
      - POSTGRES_PASSWORD=odoo
      - POSTGRES_USER=odoo
      - PGDATA=/var/lib/postgresql/data/pgdata
    volumes:
      - ./odoo_db_data:/var/lib/postgresql/data
    restart: on-failure

Start with docker-compose.yml and the reported Nginx upstream request for /websocket on port 8072. Check how the Odoo 17 container exposes and listens on that port, then verify the Nginx connection path; done means clients can reach the websocket endpoint without the reported upstream errors.
