Using Stripe

I created a link in Stripe for my product.
I have tested the link in my browser successfully.
I installed it on a page in UI Builder/ using iframe
I appears it’s trying to load the page but no success.

Here is the link that Stripe published
Can this method be used.
When I run webpage inspect iI do not see any red flags.
