Description of issue:

Unable to GET torrent from private tracker - 403 Forbidden error

I have added my RSS directly too uTorrent and it doesnt show any errors, downloads just fine. I tried the same in the uTorrent web-ui with a direct link to the Torrent file and it also worked.

I have reset my TorrentLeech RSS key several times incase that would be the issue, but it gives me the same 403 Forbidden error.

From the looks of things its that Sonarr User-Agent is blocked from TorrentLeech all of a sudden.
