domain refuses to connect using advanced iframe

I installed Advance iframe and am able to embed the following link –> https://cleversequence.com/

but am receiving an error when using this link –> https://partner.deringconsulting.com/courses/13/about

I receive an error on the page — partner.dering.com refuses to connect.

The page I need help with: https://elevatelegacy.com/work-at-home-wellness-course-offer/

This is because the page has a x-option header set:

(index):1 Refused to display ‘https://partner.deringconsulting.com/courses/13/about’ in a frame because it set ‘X-Frame-Options’ to ‘sameorigin’

If you like to include this page you need to ask the owner to remove this header.

Best regards,
Michael
