Can you confirm that the request method is set to POST?
I am using the post method. The preview also displays the correct info
from my twitter account. So it appears to be grabbing the form fields, but
not communicating with Marketo.

Twitter is sunsetting the Lead Gen Card on 1/10/2017. It's been down for months already due to a bug on the Twitter side. Now they're shutting it down entirely.
