Curious if this is a regional thing: I'm in Australia and Nopy has always been terrible for me. So I almost never use it... I tried again on this file, and it averaged 72 KB/s, took 40 minutes, failed and restarted 11 times, and when it was supposedly "done" the hash apparently didn't match and I couldn't extract it anyway.
So I grabbed it from Zippy instead, which cost 20 seconds and a blocked popup.
Personally, from my part of the world my next preference if no Mega link is available has generally been Workupload. Good speeds, no nonsense.
