I was successfully connecting to NZBPlanet indexer a few days ago, it went down and now i’m getting the following error. I can get to their API through a web browser but Sonarr is not liking it.
i was getting a ton of failures connecting to the indexer when it was down, and it seems like Sonarr has just blacklisted the indexer!! (although i’m not sure thats possible). I tried deleting the indexer and recreating but now i get the error every time i try to create and test it.
Please help
