Yes I downloaded it with jD2.
I think I figured out what causes it to fail and what gets the video to download...
When pasting your cookies:
jDownloader is checking the cookies
Then, after waiting a while for it to check you get this error
After the check turns orange "unknown error" and you try to start a download, it will say "blocked by cloudflare...
To circumvent the error and start the download you have to be quick:
When pasting your cookies, immediately go to downloads and force start your video download before the jD check gets orange.
In case you are to slow and you get the blocked by cloudflare message again, just stop all downloads, go back to account management
right click on your recurbate entry and select refresh (you don't have to paste the cookies again in this case).
Now immediately go back to downloads (you only have a few seconds) and force start your downloads.
