Document the reverse proxy setup and container-restart gotcha
All checks were successful
Deploy / deploy (push) Successful in 22s

Records what wasn't discoverable from the repo alone after today's
outage: Cox blocks inbound port 80 so certs must use DNS-01, the apex
proxy host's destination has drifted before, the NPM UI can show a cert
as valid/in-use while nginx presents none on disk, and restarting via
the Unraid Docker UI throws "No such container" after every deploy
because Compose gives the container a fresh ID each time.

pipeline mechanics. Push to `main` on the `forgejo` remote
(`https://git.hippofam.com/ninja_hippo/arr-summary.git`) triggers
`.forgejo/workflows/deploy.yml`, which syncs into

**Restarting the container manually: use Compose, not the Unraid Docker
UI.** Every deploy recreates the container with a new Docker ID (same
name, `arr-summary`). Unraid's Docker tab caches the old ID, so hitting
Restart there after a deploy throws "No such container" — harmless, but
confusing. From the Unraid terminal:
```bash
cd /mnt/user/appdata/greendale && docker compose restart
```
`docker compose up -d --force-recreate` for a guaranteed-clean recreate;
`docker ps --filter name=arr-summary` to check real state regardless of
what the Unraid UI shows.
## Reverse proxy (Nginx Proxy Manager)
Two NPM proxy hosts front this app and `git.hippofam.com`, both using
Let's Encrypt certs issued via **DNS-01 through Porkbun** — required,
not optional: **Cox blocks inbound port 80** on this connection, so
HTTP-01 challenges (and plain `http://` requests generally) can never
work here. `http://hippofam.com` will always time out from outside the
LAN; only `https://` resolves. Both proxy hosts have Force SSL on.
`hippofam.com` → `http://192.168.86.33:5055` (the Unraid box, this
container's port). Verify the destination IP/port here before assuming
an outage is DNS or app-level — it has drifted to the wrong host before.
On 2026-08-26 the apex host's own cert (issued Aug 2025) went dark: NPM's
UI still showed it "In Use" with a valid, unexpired date, but nginx
presented no certificate at all for `hippofam.com` (TLS alert 112,
"unrecognized name") — the on-disk cert files had rotted independently
of the DB record NPM's UI reads from. `git.hippofam.com`, on a newer
cert from the same account, was unaffected. Fixed by pointing the proxy
host at the `*.hippofam.com` + `hippofam.com` wildcard cert already
issued and sitting unused, which forced NPM to regenerate the nginx
config with known-good cert files. If `hippofam.com` ever throws a TLS
handshake error again with NPM's UI reporting all green, suspect this
same on-disk/DB drift before anything else — check with:
```bash
openssl s_client -connect <public-ip>:443 -servername hippofam.com </dev/null
```
A clean run shows `subject=/CN=...` and `Verify return code: 0`; the
broken state shows `no peer certificate available`.
**Persistent state, never touched by deploys:** `.env` holds every API key
and `LOGIN_PASSWORD` — this project was already doing this correctly
before the Forgejo migration (compose file uses `${VAR}` substitution from
