While your grammar, spelling, and punctuation are less than desirable, I'll enlighten you.
There are a few reasons: Your router is not supporting uPnP OR Bitcomet is not sending out uPnP requests to your router and your router is not letting in torrent connections, therefore you need to go and port forward them manually.
You also need to take into account, has Windows automatically added exceptions for your Torrent program or have you added exceptions to your Windows Firewall? (assuming you are using Windows)
I am not a fan of Bitcomet, I would recommend uTorrent instead.
