I am trying to set-up Sonarr (installed locally) and have it connect to rTorrent on my seedbox. I have gone into Download Client and added rTorrent. I have configured with host, port, URL base, username, password. When testing the set-up it returns the error “Unknown exception: Response from server does not contain valid XML.” Any ideas what is wrong? I have tried various things and searched but cant work it out. All help appreciated.
