Why isn't my 'Buy Now' payment option working?

[DjungelochJazz]

Hi,

I get the error "Checkout is currently unavailable due to technical problems. Please try again in a few minutes." every time i use the Apple pay button. I have read all other post about this issue and have tried plenty of different browsers and phones. I have had the page live for three months without any password, I have everything setup according to the earlier posts. 

Please help me get my payment working as they should.
