I've been looking into this recently. Nord VPN and others can be great for downloading on public trackers with great speeds. However Nord VPN and others are terrible for private trackers like here. A lot of VPNs including Nord, prevent you from seeding so you cant upload for shit, messing up your ratio.
@IncubusAZ This is what Nord say about it "Port forwarding and triggering could work with a VPN protocol in general, but not with NordVPN. Our apps block almost all port communication from within your device except for the ones most commonly used by popular applications. This was a tough decision that may inconvenience some users, but we’d like to explain why we did this...." https://nordvpn.com/blog/port-forwarding/
I was wondering for ages why I couldn't seed for shit and I think this might be it.
