On an old Mac Mini running the last available OS X version, 10.7
Sonarr 2.0.0.5059
Mono 5.2.0.224 (also rolled back to mono 5.0)
Unable to connect to indexer: Error: SecureChannelFailure (One or more errors occurred.): (indexerURL here)
(The URL works in a browser)
Detail below seems to mean it’s in Mono SSL stuff. I read a suggestion to downgrade to Mono 5.2 but that didn’t change anything. Suggestions appreciated, thanks.
