A couple of methods. Shutdown Router then same to computer. Disconnect all external drives. Restart Router and connect computer via Ethernet Cable ( Wifi is iffy ) Restart computer in Safe Mode ( Shift ) - immediately at startup. It does Repair Disk, Clears cache and only loads Apple Software and Fonts. Load slowly - normal. Try again and if possible do not let computer to go into Sleep or Screen Saver mode.


If over Wifi - same as earlier except Disconnect All Other devices using the wifi - what the Max Bandwidth for this computer.
