Dell Recycling refuses to print shipping label, #3

I'm trying this link https://www.dell.com/en-ca/dt/corporate/social-impact/advancing-sustainability/how-to-recycle/pcs-and-laptops/mail-back-form.htm#scroll=off

and I'm getting the error message "Unfortunately, we cannot generate your shipping label due to technical errors. We apologize for the inconvenience. Please try again later."
