UE 4.7.6 downloading error why?

I have 4.7.5 when I’m trying to download update, a message appear after waiting 10 min says “Cannot download update patch”. I’m sure it’s not Internet connection problem, my connection is fast.
I tried enabling debug login but still same problem.

How to fix this ???
