Question about Sonarr and Radarr

Sonarr version

Hello I use sonarr and radarr with a subscription to dediseedbox. But for quite some time when I reload film / series on sonarr or radarr I have this error which appears. I looked on the tracker I use (yggtorrent french tracker) and the torrent that I am looking for its available on the site
Do you know where it can come from please ?

Thanks for your answers guys.

First thing I would do is go and see if you can download the file through jacket and look at the logs there.
