Thank you for the suggestions but unfortunately neither of those are the issues.
I am familiar with torrent queuing and have both my upload and download queues set appropriately (10 active downloads and uploads)
I also know that all these torrents have active seeders because the tracker is reporting uploaders on the website.
I’m pretty certain this is an issue with resolution of the tracker with my client because if I can get it to resolve (in the past through force reannounce) everything downloads as expected.
