APP generates wrong URL

[msi-tl]

Describe the bug Since Nextcloud APP version 3.7.19 (NC 20.0.9 and 20.8.1) in combination with Collabora Online - Built-in CODE Server 6.4.705 it's not possible to open documents over a public domain. The richdocuments app generates a URL for the local address of the server.

To Reproduce Steps to reproduce the behavior:

1. Install NC 20.0.9 with Collabora Online v 3.7.19 and Collabora Online - Built-in CODE Server 6.4.705
2. Create or open a file (don't care if a document, table or presentation)
3. The document doesn't open -> F12 tools show a url with local ip instead of the FQND
4. Additional read value of public_wopi_url from cli -> /occ config:app:get richdocuments public_wopi_url
5. See the variable with local IP instead of FQND. "wopi_url" has the FQND.

Expected behavior The public_wopi_url should have the FQND instead of the local IP of the server. Documents should open propertly.

Can you tell how you installed the richdocumentscode app in the beginning? Was it through CLI? Do you have an overwrite.cli.url set in your config.php?

Hi @juliushaertl,

i can reproduce the bug.

My setup:

This is my docker-compose running on a docker server:

version: '3.7'

services:
  # Database
  mariadb:
    image: mariadb:latest
    container_name: nextcloud_test_db
    command: --transaction-isolation=READ-COMMITTED --log-bin=ROW --innodb_read_only_compressed=OFF

      - ./data/nextcloud-db:/var/lib/mysql
    restart: unless-stopped
    environment:
      - TZ=UTC
      - MYSQL_INITDB_SKIP_TZINFO=1
    env_file:
      - mariadbadmin.env
      - mariadb.env
  
  # Redis
  redis:
    image: redis:alpine
    container_name: nextcloud_test_redis
    restart: unless-stopped
    volumes:

    command: redis-server --requirepass TEST

  # Nextcloud Web

    # Nextcloud cron
  cron:
    depends_on:
      - mariadb
      - redis
    image: nextcloud:stable-apache
    container_name: nextcloud_test_cron
    restart: unless-stopped
    volumes:
      - ./data/nextcloud-www:/var/www/html
      - ./data/nextcloud-data:/mnt/nextcloud-data
    entrypoint: /cron.sh

networks:
  traefik_proxy:
    external:
      name: traefik_proxy

In the config.php i changed 'overwrite.cli.url' => 'https://cloud-test.example.com',

This is the config for the app richdocumentscode:

php occ config:app:get richdocuments wopi_url is set to: https://cloud-test.example.com/custom_apps/richdocumentscode/proxy.php?req= and php occ config:app:get richdocuments public_wopi_url is set to https://cloud-test.internal.example.com/custom_apps/richdocumentscode/proxy.php?req=

The install is just docker-compose up -d and click next > next in the web ui.

Did you initially setup/install richdocumentscode + richdocuments while connected via http://<ip_address> by chance?

What happens if you either change the wopi_url/public_wopi_url from the command-line or change/re-save settings under Admin settings->Office?

The public_wopi_url gets populated I think from the Capabilities returned via `https://<domain.tld>/<apps_dir>/richdocumentscode/proxy.php?req=/hosting/discovery

Though there could be other possibilities too.
