No doubt this question has been asked a lot, but, I've tried downloading the latest NVIDIA drivers so I can play my games, but I'm stuck. The Software Updater just doesn't work; it asks me to check my internet connection, which is working fine. When I tried looking for them on the NVIDIA website, all I got were links to these forums.
Try a different server at Software&Updates>Zorin Software.
At "Download from" select main server or if it doesn't work another server. You can make a test there to find the best download server.
The servers are probably overloaded at the moment.
Additionally, after you boot up your computer, and you click on your name at the login screen, a icon appears on screen. Select Zorin Desktop, not Wayland.
