I have been planning to use my rpi as torrent downloader. I did work for a while. but suddenly it stopped connecting to torrent trackers rendering it unable to download any torrents. at the same time, my desktop which is connected to the same router my rpi is connected is able to connect to trackers and download torrents.
any network configs I should change. please note that it used to work before. and afaik, the rpi is reaching to the tracks but cannot connect to it.
EDIT 1: I have tested different ports for incoming connections. The port is open but it is not downloading.
