Running v1.31.0 in Docker on a Synology 918+ and my series requests are failing. Sonarr is also running in Docker on the same NAS. Docker images are all latest from LinuxServer.io.
When testing the Sonarr connection, it shows the error "Failed to connect to Sonarr". I've found the following errors in the logs:
2023-01-07T11:57:00.026Z [error][Download Tracker]: Unable to get queue from Sonarr server: 4K TV Shows
2023-01-07T11:57:00.024Z [error][Download Tracker]: Unable to get queue from Sonarr server: TV Shows
2023-01-07T11:56:02.373Z [error][Sonarr]: [Sonarr] Failed to retrieve profiles: connect ECONNREFUSED ::1:8989
I recognise the connection is refused but my configuration hasn't changed and Radarr continues to operate normally (identical setup, also in docker).
