Sonarr has been working beautifully for months on my DiskStation NAS but recently can’t connect to any indexer. I’ve restarted Sonarr but no difference. For instance, in trying to add KAT the log shows the following:
Unable to connect to indexer: Error: NameResolutionFailure
System.Net.WebException: Error: NameResolutionFailure
