Mautic form action not working

I have a custom form on my website and included the action URL from a Mautic form I created. The newsletter box can be seen on https://blog.okadabooks.com/video-adichie-with-trevor-noah-daily-show/

Each time the form is filled, I get the error “This form is no longer available.” even though the form is clearly still on the Mautic dashboard.

Does Mautic support getting data from forms that just hold the action URL? With all the fields properly tagged?
