使用 Docker 和 nextcloud-fpm 的 Nginx 超时错误

Question

我有一个使用 nginx、nextcloud-fpm、mariadb 和 redis 的 docker-compose 文件（见下文）。mariaDB 和 Redis 连接似乎正常，但我无法让任何类型的 Web 界面（通过 nginx 端口 80 访问）工作。每次连接尝试都会在几分钟后超时，并且 Nginx 没有提供任何日志来排除故障。

我对 nginx 还不熟悉，所以任何帮助我都会非常感激。注意：我已经设置了反向代理，只需要 nginx 作为 Web 服务器，所以我不关心 TLS，只需要它在端口 80 上工作。此外，.env 文件实际上只是引用密码。

尝试在浏览器中访问http://10.0.0.234:8008

docker-compose.yml

version: '3.7'
