Hi Dear Nextcloud community,

I’ve been experiencing an issue (as many others) where documents don’t open for users who aren’t connected via tunnel:

"Failed to read document from storage, please try to load the document again.".

This problem appeared suddenly today after updating the containers yesterday. One of my colleagues created a document, worked on it for a while, and was then unexpectedly locked out of it (and most other documents as well). Between updating and her first creating the doc were at least 12 hours and it worked for here a few yours.

I’ve read through the documentation, but for a setup that’s marketed as “all-in-one,” there seems to be a lot of manual configuration necessary for what I consider a basic use case.

My current setup is simple:

  1. Domain/DNS points to our server

  2. Using Caddy as reverse proxy with Docker Compose

Here are my configuration files:

Caddyfile:

https://cloud.example.com:443 {
    header Strict-Transport-Security max-age=31536000;
    reverse_proxy localhost:11000
}

compose.yml:

services:
  nextcloud:
    container_name: nextcloud-aio-mastercontainer
    image: nextcloud/all-in-one:latest
    restart: always
    ports:
      - "8080:8080"
    environment:
      - APACHE_IP_BINDING=127.0.0.1
    volumes:
      - nextcloud_aio_mastercontainer:/mnt/docker-aio-config
      - /var/run/docker.sock:/var/run/docker.sock:ro
    depends_on:
      - caddy

  caddy:
    container_name: caddy
    image: caddy:2
    restart: always
    network_mode: "host"
    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile
      - caddy_data:/data
      - caddy_config:/config

volumes:
  nextcloud_aio_mastercontainer:
    name: nextcloud_aio_mastercontainer
  caddy_data:
  caddy_config:

I believe the Nextcloud project would benefit from a collection of tested, working configuration examples. I’d be happy to contribute to development/documentation efforts if I can help improve this aspect.

Many thanks in advance for any help! <3
