I updated Plex to version 0.9.12.3, and now when Sonarr tries notify Plex I get an error message.
Message:
Unable to connect to Plex Server: Unexpected character encountered while parsing value: <. Path '', line 0, position 0.: Unexpected character encountered while parsing value: <. Path '', line 0, position 0.
Exception:
