Boot into Safe Mode according to How to use safe mode on your Mac and try downloading and installing from there.
Note: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will assure a successful boot into Safe Mode.
Disable VPN and other 3rd party software that might be blocking the contact and try again to connect to the Apple Update server.
