求教-digitalocean nginxconfig.io 的这个配置怎么改

想在 xx.com 和 www.xx.com 下放一个静态的 bei an 页 index.html
但是一直 502 Bad Gateway

尝试 docker-compose.yml 文件夹下的这两个路径都放了 index.html ，但是还是 502

./www/xx.com/public/index.html
./www/xx.com/index.html

nginx 使用 docke 部署

version: '3'

services:
  nginx:
    container_name: nginx 
    image: nginx:latest
    restart: always
    ports:
      - 80:80
      - 443:443
    volumes:
      - /etc/localtime:/etc/localtime
      - ./nginx.conf:/etc/nginx/nginx.conf
    
      - ./conf.d:/etc/nginx/conf.d
      - ./log:/var/log/nginx
      - ./www:/var/www

      - ./sites-available:/etc/nginx/sites-available
      - ./nginxconfig.io:/etc/nginx/nginxconfig.io
      - ./ssl:/etc/nginx/ssl
      - ./dhparam.pem:/etc/nginx/dhparam.pem
