Question

编辑：添加了docker-compose.yml和pretix配置
大家好
我正在尝试使用此Pretix在服务器上运行docker-compose.yml。我刚刚将traefik标签更改为我的nginx环境变量，并调整了外部网络以使其与我的nginx网络匹配，但其他所有操作都是相同的。但是，当我转到自己的网站时，只看到带有内部服务器错误消息的pretix徽标。
浏览日志时，我发现pretix_app无法连接到数据库，但是我真的不明白为什么。

pretix_app | django.db.utils.OperationalError: (1045, "Access denied for user 'db'@'172.20.0.24' (using password: YES)")
