@sername1985-0 No... This is definitely NOT why you are having an issue. This error you are seeing is a SCRAPE error, which generally only comes up when you are not actively trying to seed the torrent. This error is because our tracker does not support scrape.
You could have a queuing issue in your torrent client, limiting the number of torrents that are actively seeding. It may be worth giving your settings a glance and see if you can find where this setting is located.
