@nikgl That failure appears typically if you don't enter a tracker announce URL when creating the torrent.
You can use any valid URL, for example https://tracker.gaytorrent.ru . The GayTorrent.ru system will rewrite it (and thats where the failure message comes from, there isn't a 'key' for the URL to rewrite if there's put no URL).
If you use your personal announce URL looking like https://tracker.gaytorrent.ru/<here_your_personal_passkey>/announce
(you find it in the properties of torrents downloaded from GayTorrent.ru) and set it to private, you may save to redownload the .torrent file after the upload to get it seed.
BTW: I can access the upload guide...
