Loaded torrents disappear after restarting container

In the log of cloud-torrent inside the container I see:

`/ # cloud-torrent -l
2018/06/06 17:05:37 Loaded new search providers
2018/06/06 17:05:38 couldn't open piece completion db in "/downloads": timeout
2018/06/06 17:05:38 initial configure failed: listen tcp 0.0.0.0:50007: bind: address already in use
`

Please help me, I wanna use this as my main torrent downloader.

Thanks a lot.
