求指导，数据库连不上

[bestZwei]

显示{"code":0,"msg":"连接数据库失败：数据库地址填写错误！"}

我在1panel使用的 docker compose:

version: '3'
services:
  dnsmgr-web:
    container_name: dnsmgr-web
    stdin_open: true
    tty: true
    ports:
      - 8085:80
    volumes:
      - /volume1/docker/dnsmgr/web:/app/www
    image: netcccyun/dnsmgr
    environment:
      - DB_HOST=localhost # 1Panel-mysql-JDMB 也试过
      - DB_PORT=3306 
      - DB_USER=root1
      - DB_PASSWORD=12KJ3456 
      - DB_DATABASE=dnsmgr
    networks:
      - dnsmgr-network


networks:
  dnsmgr-network:
    driver: bridge
