Is my website slow

Hey guys, I've just been playing around with my website and the page is loading slow: https://www.andrewsdevelopments.com.au/services2

Anyone else having the same issue with my page? And if so, any tips on making it load faster?

the /services2 page throws an error

the rest of the site loads okay for me, and I'm on a VPN atm

one comment, the navigation menu is kinda lost on the main site with the background video
