Thanks,
I;ve enabled labels in Deluge and managed to set a torrent to have a label, however when i alter the download client settings in sonarr to include the label, i get th following error in red at the top of the screen :
Test was aborted due to an error: Unknown method
in the sonarr logs i get :
NzbDrone.Common.Exceptron.ExceptronApiException —> System.Net.WebException: The remote server returned an error: (503) Server Unavailable.

as soon as i remove the label from the settings, it tests and saves fine.
SCRAP THE ABOVE…
I had to restart deluge for it all to take effect… it’s working now 
thank you!
