Sonarr/Radarr lose connection to sabnzb

Hi,

I’ve installed sabnzb with radarr and sonarr, it mostly works fine but when i’m either reading/scanning or checking things on the HDD it seems, e.g. plex lib scan or radarr full scan. Sonarr mostly, but sometimes radarr decide they can not conncetion to sabnzb.

I get the error in sonarr “All download clients are unavailable due to failures”

Close

But at the same time radarr would work or vica versa.

Anyone has any ideas before i give up and just reinstall manually.
