Nextcloud Nginx 反向代理 MIME 类型问题

我在 FPM 模式下的容器设置中运行 Nextcloud。应用程序容器本身运行组件php-fpm，我还有一个额外的容器运行 nginx 作为 Web 服务器。我非常仔细地遵循这个例子：

https://github.com/nextcloud/docker/tree/master/.examples/docker-compose/with-nginx-proxy-self-signed-ssl/mariadb/fpm

这是我的 docker-compose.yml 文件：

  nextcloud:
    image: nextcloud:17.0.1-fpm-alpine
    container_name: nextcloud
    environment:
      - REDIS_HOST=redis
      - MYSQL_HOST=db
    volumes:
      - nextcloud-data:/var/www/html
    depends_on:
      - mariadb
      - redis
    env_file:
      - ./config/mariadb_nextcloud.env
    
  nextcloud-web:
    build: ./nextcloud-web
    container_name: nextcloud-web
    restart: always
    volumes:
      - nextcloud-data:/var/www/html:ro
    environment:
      - VIRTUAL_HOST={{ nextcloud_external_url }}
      - VIRTUAL_PORT=80
      - LETSENCRYPT_HOST={{ nextcloud_external_url }}
    depends_on:
      - nextcloud

这是nginx.conf复制到 nextcloud-web 容器中的文件（基于 Nginx，除了添加配置文件外没有进一步的更改）：

这几乎是上面链接中的标准配置。在这个容器前面，我使用的是Nginx-proxy带有 letsencrypt 配套程序的知名容器。大多数 Nextcloud 安装都有效（Web 前端、上传/下载、应用程序、大多数管理门户）。但是，我最近安装了一个自定义应用程序（SAML 配置），并且它的管理页面没有加载，而是给我带来了大量以下错误：

Content Security Policy: The page's settings blocked the loading of a resource at inline ("script-src").
The resource from “https://<my-url>.tld/apps/files/” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).
The resource from “https://<my-url>.tld/apps/files/” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).
The resource from “https://<my-url>.tld/apps/files/” was blocked due to MIME type (“text/html”) mismatch (X-Content-Type-Options: nosniff).

知道这是怎么回事吗？如能提供任何帮助，我将不胜感激。

原来这是文件权限问题。Web 容器没有custom_apps文件夹的读取权限，因此无法提供请求的文件。我不知道为什么它没有给出更有意义的错误消息。
