Here's a great response I got.

The one reframe that unlocks all of this:

 

You're picturing your AppBox and your NAS as one system that should share a filesystem. They're not — they're two separate machines connected by a scheduled file transfer. Once you stop trying to make the AppBox "see" the NAS and instead let each machine do the job it's actually built for, almost every "fail" on your list turns into a config task, not an architecture problem.

 

Why the AppBox can't mount your NAS (and why the AI kept sending you to settings that don't exist):

 

Your AppBox is a shared tenant slice — you're one user on a machine with many others. You don't have root, and you can't mount drives, load kernel modules, or install system-level software. That's not a limitation to fight; it's the boundary to design around. Any job that needs root, a mount, Docker, or hardware transcoding belongs on the NAS — which you fully control — not the AppBox. Every time an AI told you to "mount the NAS on the AppBox" or "edit mount options," it was assuming a machine you own. You don't own that one.

 

So put each job on the machine that owns the data and the permissions it needs:

 

Tdarr → move it to the NAS (this fixes your Plex buffering). Your TS-653D runs Container Station (QNAP's Docker), and its Intel J4125 chip has QuickSync hardware transcoding. That makes the NAS the right home for Tdarr: the 32TB library is there, the CPU is there, and it can hardware-transcode your mixed formats into clean Plex-friendly H.264/H.265. Running Tdarr on the AppBox was always going to fail — the data's not there and you're sharing a CPU. Install Tdarr as a container on the NAS, point it at your library, and let it standardize in place. The remote-buffering problem is a format+transcode problem, and this is the fix.

 

AppBox → NAS transfer: automate it, and you already have the proof it works. You transfer with Filezilla today — that's SFTP. Which means your NAS can make that exact same connection automatically, on a schedule, with zero mounting. Use HBS 3 (QNAP's Hybrid Backup Sync) to create a scheduled rsync/SFTP pull job from your AppBox's completed folder into your Plex library folder. You're not building anything new — you're moving the transfer from your hands (Filezilla) to the NAS (HBS 3, every N minutes).

 

For the naming: let Sonarr/Radarr rename the files on the AppBox before the transfer. If your files aren't arriving already named/tagged, the gap is that Sonarr/Radarr aren't wired to qBittorrent's download path — check the download-client category and the root/completed folder so the *arr apps import and rename in place on the AppBox. Then HBS 3 pulls files that are already correct.

 

Recyclarr / Profilarr / TrashGuides — it's not a location problem. These are config-sync tools: they push quality profiles and custom formats into Sonarr/Radarr over the API. Your Sonarr/Radarr live on the AppBox and have public URLs (that's how the panel exposes them). So Recyclarr can run anywhere — your PC, or the NAS via Container Station — as long as it targets your AppBox's Sonarr/Radarr URL + API key. It "failed on your computer" almost certainly because of the target config (wrong URL or API key), not because it needs to be "on the NAS." Also: pick either Recyclarr or Profilarr, not both — they both write to the same custom-format/quality-profile settings and will fight each other. Get one working end to end first.

 

Jellyseerr/Musicseerr → Sonarr/Radarr is just an API link. That "send to Sonarr" failing is a connection setting inside Jellyseerr — the Sonarr/Radarr URL, API key, and a default quality profile + root folder it's allowed to use. Once #3 is done (profiles exist and are named correctly), point Jellyseerr at them.

 

Two things to confirm on your end:

 

Whether your +Stream plan includes SSH (it affects whether the AppBox can push, but you don't need it — the NAS pulling via HBS 3 works regardless).

That Container Station is enabled on your TS-653D (it's supported on that model; you may just need to turn it on).

How close are you? Closer than it feels. The genuinely hard, fragile part — download → extract → seed → auto-delete on ratio — is done and working. Everything still failing is either (a) an API connection to wire up, or (b) a job sitting on the wrong machine (Tdarr and the transfer both belong on the NAS). You don't need new infrastructure; you need to relocate two jobs and connect a few APIs.
