# Prowlarr
|
||
|
||
Prowlarr is the indexer management layer for the *arr stack. It hosts the
|
||
indexer definitions and exposes them as Torznab feeds and downloads;
|
||
Sonarr, Radarr, Lidarr, and Readarr query those feeds and receive results.
|
||
|
||
**Host:** Dankserver — **Hostname:** `prowlarr.dankserver.local` — **Docs:** https://wiki.servarr.com/prowlarr
|
||
|
||
## Facts

| Item | Value |

|------|-------|
|
||
| Image | `lscr.io/linuxserver/prowlarr:latest` |
|
||
| Port | 9696 (host) → 9696 (container) |
|
||
| Min RAM | 256 MB |
|
||
| Auth | Forms (web UI) + API key (`/api/v1/...` and feed routes) |
|
||
|
||
## Live wiring (verified end-to-end 2026-08-30)
|
||
|
||
Indexer queries flow **through** Prowlarr; a grab hands off to the querying
|
||
app's own qBittorrent download client. Feeds are per-indexer:
|
||
|
||
```
|
||
http://prowlarr:9696/{indexerId}/api?apikey={GLOBAL_KEY}&t=caps|search|tvsearch|movie|music|book&...
|
||
http://prowlarr:9696/{indexerId}/download?link=...&file=... (torrent handoff)
|
||
```
|
||
|
||
| App | Indexer row | Prowlarr id | Categories | Status |
|
||
|---|---|---|---|---|
|
||
| Radarr | Prowlarr-YTS | 7 | [2000] | ✅ grabbed + imported 2160p Dark Knight 2026-08-30 |
|
||
| Sonarr | Prowlarr-Nyaa | 4 | [5000] | ✅ connection validated (202) |
|
||
| Lidarr | Prowlarr-Nyaa | 4 | [3000] | ✅ connection validated (202) |
|
||
| Readarr | Prowlarr-Byrutor | 3 | [7000] | indexer valid; download client parked |
|
||
|
||
The global API key is in `config.xml` (`<ApiKey>`); per-application keys are
|
||
only used by Prowlarr's own sync calls, NOT by the feeds. The arr download
|
||
clients authenticate to qBittorrent with the permanent WebUI password stored
|
||
in `/home/dank/.qbpass` (mode 600) on Dankserver.
|
||
|
||
**Readarr caveat:** Readarr is abandoned upstream (last release 0.4.x); its
|
||
qBittorrent client cannot authenticate against qB 5 (`Authentication
|
||
failure` on the connection test while Sonarr/Lidarr/Radarr pass with the
|
||
same credentials). The books pipeline is parked pending a Readarr successor;
|
||
the indexer row itself is healthy.
|
||
|
||

||
## Gotchas (all verified live 2026-08-30)
|
||
|
||
- **The feed route is `/{indexerId}/api`.** There is no `/torznab/{id}/feed`
|
||
— that path (and any other unmatched path) hits the Forms-auth catch-all
|
||
and gets `302 → /login?returnUrl=…`. An arr following the redirect parses
|
||
the login HTML and fails with a cryptic
|
||
`'/' is an unexpected token … Line 54` XML error that looks like an auth
|
||
problem. It is a path typo. Source: `NewznabController`
|
||
(`[HttpGet("{id:int}/api")]` + absolute
|
||
`/api/v1/indexer/{id}/newznab`).
|
||
- **The arr's Torznab joiner is `TrimEnd(baseUrl,'/') + apiPath` with NO
|
||
separator.** `baseUrl="…/7/" + apiPath="api"` silently becomes `…/7api`.
|
||
Either keep the leading slash on `apiPath` (`"/api"`) or end the baseUrl
|
||
with `/api`.
|
||
- Categories in the indexer row must be a subset of what the feed's `caps`
|
||
advertises; extras log "does not support the following categories" and
|
||
some feeds reject them.
|
||
- **A freshly created indexer row defaults to all-off.** If `enableRss`,
|
||
`enableAutomaticSearch`, or `enableInteractiveSearch` aren't set, the
|
||
app logs `Searching indexers for [X]. 0 active indexers` (Lidarr,
|
||
verified). Search proves TV + music chains 2026-08-30: Sonarr returned
|
||
76 live releases for an anime term, Lidarr 18 for YOASOBI – THE BOOK,
|
||
all via the Prowlarr-Nyaa feed.
|
||
- The v1 API collection is `/api/v1/applications` (not `/api/v1/app`);
|
||
GET responses carry `fields: []` — real settings values live in
|
||
`prowlarr.db` → `Applications.Settings` JSON (read-only inspection).
|
||
- Instance name/`InstanceName=Prowlarr` in `config.xml` does NOT prefix the
|
||
API/feed routes on this build (they answer at root; the `/Prowlarr/...`
|
||
prefix 302s to the SPA).
|
||
- **Application auto-sync cannot manage these rows** (they carry
|
||
`SyncLevel=2`): `POST /api/v1/applications/test` fails with
|
||
`Unable to cast object of type 'NzbDrone.Core.Thing…'` — Prowlarr v1
|
||
cannot deserialize Radarr 6.3's newer response types. The manual Torznab
|
||
rows above are therefore the real integration; sync neither duplicates
|
||
nor clobbers them.
|
||
- Prowlarr runs `AuthenticationMethod=Forms` + `AuthenticationRequired=Enabled`
|
||
healthily — the DryIoc crash combo was `None`+`Enabled` only (see
|
||
[[radarr]] auth notes).
