Nopy is hit and miss, they are new, and still in beta, so they occasionally have issues, but recent BS aside, they have been pretty good most of the time. Part of this is over use.Why are 3/4 of the Windows links garbage?
Filesupload leads to re-direct shit. Uploadhaven has a nginx error. Nopy is always trash because it takes 3 hours to download something.
Uplaod haven works for me all the time.
Get a downloader (like Jdownloader2 or something), and you will have a lot less problems.
