I keep getting The request timed out. and the mojave update will not load. HELP

Try using a Ethernet cable connection instead of Wi-Fi. I don't know the speed of your internet connection or the number of devices you have using it all at the same time. Try reducing the number of devices using your internet service connection while you are downloading the update.

You could also try downloading in Safe Mode.

Use safe mode to isolate issues with your Mac - Apple Support

Try this.

This won't load either.
