Failed to establish secure https connection to Jackett Indexers

[Logvin]

Sonarr version (exact version): 2.0.0.5153
Mono version (if Sonarr is not running on Windows):4.6.2
OS: Ubuntu 17.10
Debug logs: Unable to connect to indexer: Failed to establish secure https connection to ‘https://my.domain/jackett/UI/jackett/api/v2.0/indexers/iptorrents/results/torznab/api?t=caps&apikey=api_key_removed’, libcurl fallback might be unavailable.

Description of issue: Installed Sonarr on a new system, went to set up my indexers in Jackett. Works great there, but Sonarr refuses to allow them to be added. I get the error message above.

I can execute “curl https://google.com” and it returns HTML, but when I "curl " + Torznab feed URL it does not return anything.

curl is avaialble by default, but libcurl may not be. Turn on trace logging, then restart Sonarr, it’ll log more details about trying to fallback to libcurl or install mono 5.0+ and not worry about it.

I checked my versions…

So it is still not working, but the error is different.

Unable to connect to indexer: HTTP request failed: [401:Unauthorized] [GET] at [https://my.domain/jackett/api/v2.0/indexers/iptorrents/results/torznab/api?t=caps&apikey=api_key_hidden]

[markus101]

That’s a different error: unauthorized so bad username + password or API key.
