PDF embed for https pages

[Yonatans]

Hi,
I am trying to utilize the PDF embed API.

When I create a new project, I need to provide the allowed domain.

my domain is https://pages.mysite.com. When I try to add it I get an error message "Domain https://pages.mysite.com/ is invalid"

Any ideas how to support https?

Thanks!

Does that site actually exist?
