Slow speeds

So i want to download the dying light 2 which i got from fitgirl and when i get in torrenting on qbittorrent (oh i have nord vpn too) suddenly the speeds are like 0.5Mib . Couple months ago i tried downloading other games and the speeds were normal. Ive tried everything every solution from internet and and AI too but nothing always is the same the speed goes to 3.8 MiB and then to 0.5
