are you using a dailyupload premium account? download of the files is only possible with premium account, else only downloading the stream is possible. see for yourself in browser, download button will show the warning

the dailyupload stream uses the same m3u8 feature like twitter and both are failing in ffmpeg. I'm looking into a solution but it also fails with latest ffmpeg and other tools like youtube-dl, so the issue is not caused by JDownloader
