After updating to Sonarr v3, I can no longer connect Sonarr to Plex Media Server to force a library update when new content is imported. The connection was working fine with v2, and continues to work fine with Radarr. The only potential fix I could find via google was to make sure Plex isn’t set to require secure connections, which I did. I also tried it with “Use SSL” both disabled and enabled. I checked the logs, relevant part linked below, and the error doesn’t seem to be helpful. I tried purposely entering the wrong IP/port and got the exact same error.
