[BUG]我也遇到了operation time out

Describe the bug
A clear and concise description of what the bug is.

我之前是直接使用的你的compose文件，直接梭哈（正常使用），但是最近我有别的容器也会用到postgresql数据库，
我就把postgresql数据库分离出来了，作为一个单独的compose去管理postgresql，里面的账号数据这些都没动

然后修改了ttrss的compose与数据库地址信息之后，就重构容器ttrss后不正常了

Have you googled?

Deployment method

• Docker or docker-compose
• Version of the image used [e.g. latest, nightly, 19.8]

ttrss的compose：

version: "3"
services:
  service.rss:
    image: wangqiru/ttrss:latest
    container_name: ttrss
    ports:
      - 181:80
    environment:
      - SELF_URL_PATH=https://****.com/ # please change to your own domain
      - DB_HOST=postgres # 修改为新的数据库容器的服务名称
      - DB_PORT=5432
      - DB_NAME=ttrss # 修改为你的数据库名称
      - DB_USER=postgres # 修改为你的数据库用户名
      - DB_PASS=**** # 修改为你的数据库密码
      - PUID=1000
      - PGID=1000
      - SESSION_COOKIE_LIFETIME=72 # cookie 过期时间：小时
    volumes:
      - feed-icons:/var/www/feed-icons/
    stdin_open: true
    tty: true
    restart: always

  service.mercury: # set Mercury Parser API endpoint to `service.mercury:3000` on TTRSS plugin setting page
    image: wangqiru/mercury-parser-api:latest
    container_name: mercury
    restart: always

  service.opencc: # set OpenCC API endpoint to `service.opencc:3000` on TTRSS plugin setting page
    image: wangqiru/opencc-api-server:latest
    container_name: opencc
    environment:
      - NODE_ENV=production
    restart: always

volumes:
  feed-icons:

postgres的compose（进容器后感觉正常使用）：

version: '3'
services:
    postgres:
        image: postgres:13-alpine
        container_name: postgres
        ports:
          - 5432:5432
        environment:
          - POSTGRES_PASSWORD=****  # feel free to change the password
        volumes:
          - /root/docker_data/postgres/data/:/var/lib/postgresql/data # persist postgres data to ~/postgres/data/ on the host
        restart: always
