95% of jobs sent from Sonarr fail

Sonarr version (exact version): 2.0.0.5338
Mono version (if Sonarr is not running on Windows):5.18.0.240
OS: Synology Diskstation
Debug logs: https://pastebin.com/XVFYdWkU
Description of issue: +95%

I have noticed lately that the majority of jobs that are sent to my downloader from Sonarr (SABNZBD) fail.

Once the download completes in SAB, SAB marks the job as complete but i notice that it moves downloaded files from incomplete to complete folder, and fails to extract the RARs. Therefore, Sonarr never completes the job because there are no files to pickup.

SAB can download and extract files usually sent from Couch Potato or directly from uploaded NZBs.

I just don’t know where to look. I’ve posted on the SAB forum, too but have not yet found a solution.

Has anyone else noticed a MASSIVE increase in dud or fake releases from their indexers, or have experienced anything similar?
