Have you looked at the windows update history, there should be some more information there.
Also have a look in the event viewer for any particular error at that time.
Or it could possibly mean it's been pulled from the servers and they have a auto cancellation in effect for updates in mid stream through the update channel.
I had the Windows update issue on Win10, but I waited for a week and all updates were done. Firstly they weren't updating. It was showing cancelled just like your error.
