I've got sabnzbd, my indexers, and Sonarr all connected and they all work. The only thing not working is Radarr. I've copied over the API (by emailing it to myself) twice. I've made sure that the ip adresses and port were correct. I don;t kow if there is a setting on Radarr's side I've got to set before it works but I haven't seen anything about this issue.
