-# Nextcloud Admin Warnings Review
-
-## 1. Reverse Proxy Forwarded Headers
-
-**Problem:** Nextcloud doesn't see the correct client IP because Caddy isn't sending the required forwarded headers, or Nextcloud isn't configured to trust them.
-
-**Fix:** Two changes needed:
-
-**a) Caddyfile** — Caddy already sets `X-Forwarded-For` and `X-Forwarded-Proto` by default, so no Caddyfile changes are strictly needed. However, verify Caddy is on the `proxy` network and connects to `nextcloud:80`.
-
-**b) Nextcloud config** — Add trusted proxy config. Run inside the Nextcloud container:
-
-```bash
-sudo docker exec -u www-data nextcloud php occ config:system:set trusted_proxies 0 --value="caddy"
-sudo docker exec -u www-data nextcloud php occ config:system:set forwarded_for_headers 0 --value="HTTP_X_FORWARDED_FOR"
-```
-
-Alternatively, add these environment variables to `nextcloud/.env`:
-
-```
-TRUSTED_PROXIES=caddy
-```
-
----
-
-## 2. Log Errors (16 errors since March 15)
-
-**Problem:** 16 errors logged. These need to be inspected to determine the cause.
-
-**Fix:** Check the logs:
-
-```bash
-sudo docker exec -u www-data nextcloud php occ log:watch
-# or
-sudo docker exec -u www-data nextcloud php occ log:list
-# or read the log file directly
-sudo docker exec nextcloud cat /var/www/html/data/nextcloud.log | tail -50
-```
-
-Review and address the specific errors. Common causes after a fresh install include missing config values (several of which are listed below).
-
----
-
-## 3. Maintenance Window Start Time
-
-**Problem:** No maintenance window configured, so heavy background jobs run at any time.
-
-**Fix:**
-
-```bash
-sudo docker exec -u www-data nextcloud php occ config:system:set maintenance_window_start --type=integer --value=1
-```
-
-This sets the maintenance window to start at 1:00 UTC (3:00 AM CEST). Adjust the value (0-23) to match your low-usage hours.
-
----
-
-## 4. MIME Type Migrations
-
-**Problem:** New MIME types are available but not yet applied.
-
-**Fix:**
-
-```bash
-sudo docker exec -u www-data nextcloud php occ maintenance:repair --include-expensive
-```
-
-This may take a while on large instances but is fine on a fresh install.
-
----
-
-## 5. Missing Database Indices
-
-**Problem:** Missing optional indices on `filecache` and `properties` tables that improve query performance.
-
-**Fix:**
-
-```bash
-sudo docker exec -u www-data nextcloud php occ db:add-missing-indices
-```
-
----
-
-## 6. AppAPI Deploy Daemon
-
-**Problem:** No default deploy daemon configured for external apps (ExApps).
-
-**Fix:** This is only needed if you plan to use ExApps (like the AI assistant apps). If not, this warning can be ignored.
-
-If you want to set it up, it requires a Docker Socket Proxy or direct Docker access from Nextcloud. This is a more involved setup — see the [AppAPI documentation](https://cloud-py-api.github.io/app_api/).
-
-**Recommendation:** Ignore unless you need ExApps.
-
----
-
-## 7. Two-Factor Authentication Not Enforced
-
-**Problem:** 2FA providers are available but not mandatory for all users.
-
-**Fix:** To enforce 2FA for all users:
-
-```bash
-sudo docker exec -u www-data nextcloud php occ twofactorauth:enforce --on
-```
-
-Make sure you have a 2FA provider app installed and configured (e.g., TOTP) **before** enforcing, or you may lock yourself out. Install TOTP first:
-
-```bash
-sudo docker exec -u www-data nextcloud php occ app:install twofactor_totp
-```
-
-Then set up 2FA for your admin account via the web UI before enforcing.
-
----
-
-## 8. Default Phone Region
-
-**Problem:** No default phone region set for validating phone numbers without country code.
-
-**Fix:**
-
-```bash
-sudo docker exec -u www-data nextcloud php occ config:system:set default_phone_region --value="DE"
-```
-
-Use the appropriate ISO 3166-1 code for your region (DE = Germany).
-
----
-
-## 9. Server ID Not Configured
-
-**Problem:** No server ID set. Only matters for multi-server setups.
-
-**Fix:** Even on a single server, setting it avoids the warning:
-
-```bash
-sudo docker exec -u www-data nextcloud php occ config:system:set instanceid --value="$(openssl rand -hex 5)"
-```
-
-**Note:** Only do this on a fresh install. On an existing instance, `instanceid` is already set automatically — check first:
-
-```bash
-sudo docker exec -u www-data nextcloud php occ config:system:get instanceid
-```
-
-If it returns a value, this warning may be about a different server-id config. In that case, set `server_id` instead:
-
-```bash
-sudo docker exec -u www-data nextcloud php occ config:system:set server_id --value="nextcloud-1"
-```
-
----
-
-## Quick-Fix Summary (run in order)
-
-```bash
-# 1. Trusted proxy
-sudo docker exec -u www-data nextcloud php occ config:system:set trusted_proxies 0 --value="caddy"
-
-# 3. Maintenance window (1:00 UTC)
-sudo docker exec -u www-data nextcloud php occ config:system:set maintenance_window_start --type=integer --value=1
-
-# 4. MIME type migrations
-sudo docker exec -u www-data nextcloud php occ maintenance:repair --include-expensive
-
-# 5. Missing DB indices
-sudo docker exec -u www-data nextcloud php occ db:add-missing-indices
-
-# 8. Phone region
-sudo docker exec -u www-data nextcloud php occ config:system:set default_phone_region --value="DE"
-
-# 9. Server ID
-sudo docker exec -u www-data nextcloud php occ config:system:set server_id --value="nextcloud-1"
-```
