Preview Page Loads – Published Page Won't

Looks like You edited your page urls and order you have 3 different things going on.

The URL that is working is: https://www.laser-tag-equipment.com/request/

But above you have the link as: /request-info
Which is redirecting to: https://www.laser-tag-equipment.com/contact-us/request-info/

That indicates its a child page of contact us but its actually the other way around. You have contact as a child of Request info.

At any rate, you need to fix your urls and order.
