Bittorrent web : Not Authorised , Wipeout

i have been trying to download torrents using bittorrent web, and as Brave is my default browser, the bittorrent web opens on the Brave Tab itself. However, it cannot download and returns the message : “Oops! we’ve lost connection to your browser. Wipeout. Please restart the Bittorrent Web application.”
However, the same link n bittorrent web works fine when i use other browsers.
