Description of issue: I have a 4k and hd versions of sonarr. Both were fine until the update before last I believe. Now, the HD 2nd instance no long connects to the same indexers that are still working fine on the 4k 1st instance of sonarr. All indexers provided by Prowlarr. I can fix the connect failures, but its fails again in seconds to minutes or after the first search requested.
