[BUG] Transmission torrents not auto-starting download.

[Matteo961]

I have gotten mediamanager and transmission integration semi-working.
The thing I don't understand is that the torrent is added to transmission but it does not start auto-downloading when added. The transmission settings for this are set correctly. Running the latest 4.1.0.

Also see this error in MMS
2026-02-19 17:30:00,288 - [-] ERROR - media_manager.torrent.download_clients.transmission - get_torrent_status(): Failed to get torrent status

Traceback (most recent call last):

File "/app/media_manager/torrent/download_clients/transmission.py", line 111, in get_torrent_status

transmission_torrent = self._client.get_torrent(torrent.hash)

File "/app/.venv/lib/python3.13/site-packages/transmission_rpc/client.py", line 569, in get_torrent

raise KeyError("Torrent not found in result")

KeyError: 'Torrent not found in result

Anyone else having this ?

Hi

just to clarify: did the torrent download already start in transmission and the torrent isn't displayed in MM? Or do you mean something else.

Hi @maxdorninger. I have the same issue with Transmission auto-starting, but I don't think that is an MM bug. Instead, the issue may be a transmission-rpc library bug because some torrents auto-start, while others don't and have to click on retry download button. Even with the Start when added preference enabled.

About what @Matteo961 says, that error only happened to me when the torrent was deleted, because the method TorrentService.cancel_download returns the status after the torrent has been removed.

MediaManager/media_manager/torrent/service.py

Lines 59 to 68 in d8405fd

	def cancel_download(self, torrent: Torrent, delete_files: bool = False) -> Torrent:
	"""
	cancels download of a torrent
	:param delete_files: Deletes the downloaded files of the torrent too, deactivated by default
	:param torrent: the torrent to cancel
	"""
	log.info(f"Cancelling download for torrent: {torrent.title}")
	self.download_manager.remove_torrent(torrent, delete_data=delete_files)
	return self.get_torrent_status(torrent=torrent)

I think line 68 should be removed, and the method returns None.
