I attest that there is not an existing issue for this?

I have searched the existing open and closed issues

I confirm this is not related to a Cardigann YML Indexer

Current Behavior

With PTP, if a torrent is provided to Radarr but is removed before it's snatched, Prowlarr will start returning status code 500 (instead of 404).

These are the logs on Radarr's side, as you can see Prowlarr is responding with a 500.

Expected Behavior

An attempt at downloading a torrent that was removed from PTP should return 404.

Steps To Reproduce

No response

Environment

- OS: Linux
- Prowlarr: 2.3.0.5236
- Docker Install: Yes

What branch are you running?

Master

Trace Logs?

As you can see from the trace logs below, PTP responds with a HTML page for this torrent. I guess the problem is that the HTML page returns a 200 because it redirects to the deletion log.
