Cần hỗ trợ: Khi chạy stack arr (gluetun + ProtonVPN WireGuard → qBittorrent) với gói 1 Gbps, tốc độ tải xuống ổn (10‑15 MiB/s) nhưng upload chỉ < 100 KB/s. Người dùng không chắc bị throttling hay cấu hình sai (port‑forward, firewall, VPN). Muốn tìm giải pháp cải thiện tốc độ upload. #ProtonVPN #Gluetun #qBittorrent #VPN #Network #TốcĐộ #Upload #SelfHosted #Linux #Docker
