One idea comes to mind…
Delete the prior download of the torrent from you uTorrent Pro... then...
Try logging in, on your web browser, to your account...
THEN download the torrent anew, and see if it works then...???
OMG that is ASTONISHING. It works!
In fact, consider this. I had a gaytorrent torrent just sitting in uTorrent, doing nothing. I logged on to gaytorrent.ru. The torrent continued to do nothing, even after stopping and restarting uTorrent. I found the original torrent on my Android and restarted it in uTorrent. Still nothing at all.
So I delete it in uTorrent, and, go to my browser where I am logged in to gaytorrent.ru. I do a search and find the same torrent I had previously downloaded, and download it again. Click it, it pops up in uTorrent, and WORKS!
Now what's so bizarre is that the only way my uTorrent gets gaytorrent torrents to download, is if I am signed in to uTorrent. I would only be starting them in uTorrent if I was already signed in to the site. So I don't understand why this is working now, when I've been unsuccessful through KitKat and Lollipop at downloading from the site.
Regardless of why, THANK YOU! (and if you can explain "why", I'd love to know!)
