Torrents do not upload

[Midori]

Torrents that I have created with qbittorrent are displayed under Error and do not load. I don't know why and need help.

If it's a private tracker, you don't seed the torrent once you create it.
You upload the created file to the tracker website.
THEN you download it from the website (!).
And that is the file you have to seed.

(explanation: the website inserts the tracker address and your own private key into the file.)
