@yuvynuya Set Use uPnP / Nat-PMP port forwaring... "on" (checkmark it and restart the program). It might be that your ports aren't "open". Setting the checkmark qbittorrent will do that for you.
I would also checkmark the Use different port on each startup...
What firewall are you using? If windows Defender firewall check if QTB is an allowed program.
Start the Windows Firewall using the Run window
Press the Win + R keys on your keyboard, to open the Run window. Then, type "control firewall. cpl" Without the quotationmarks (") in the Open field and hit Enter or press OK.
Click.. Allow app to communicate through windows defender firewall ..... Check if there are checkmarks after the qbittorrent program
