7y/o Macbook, Mac OS update "Timed Out"

Hi there. I'm just trying to update my macbook so i can hopefully start streaming for the first time. Mac OS Update tool keeps saying "timed out".

Troubleshooting I've tried: Restarting the machine, Checking internet speed, Trying to download other software, successfully.

stats about my machine:

MacBook Pro (15-inch, 2017)

Version 10.14.6 (18G9323)

memory: 16 GB 2133 MHz LPDDR3
Processor: 2.9 GHz Intel Core i7

Kindly assist! i've updated my OS in apple products easily 100+ times and never encountered this
