Time out error updating program

Since the update version 8.4.0.5165 is made available, I have been stuck at 7.7% while downloading updates. Error log says Error: 0x80072ee2 - The operation timed out. My current version is 8.4.0.5076 and database version 25936. I have 3 machines with same problem Win10 version 1607 build 14393.321.

Any help is appreciated.
