qBittorrent official forums

Hello there,

I just set up my openmediavault NAS at home from an old pc. I installed the qBittorrent on it and when it's running I do not see any upload. It was running all day and still shows 0 B upload. When my own PC seeding the (same) torrents there almost 50gb upload in a day. I forwarded its port, I even changed it several times and still nothing happening. I don't know what should I do. Is there anyone who know a solution to this problem?

port forwarding: done on the correct IP and on a port >50000(TCP+UDP)?
What tells you any Googled site able to check if a port is open ? (check for "check open port")
Is UPNP used? If not disable it on QBT/Router and confirm the port used
