I have noticed that Sonarr won’t grab an episode or can’t see the release until 1 sometimes 2 days after the release comes out. Is this a Sonarr issue or a usenet issue?
The API I am currently using is from Gingadaddy. If I go to the actual site, I can see the nzb release and am able to download it, but if i do a manual or auto search within Sonarr, it doensnt find anything.
Sounds like a problem with your indexer, Sonarr should see it on the RSS feed if your indexer is publishing that properly (and Sonarr has it enabled).
The fact that search is returning no results is also a problem with the indexer, likely, you can check the logs for the URL Sonarr used and check it in a browser if you want to see what Sonarr sees (before it spits out the results).
