Checkout Not Embedding

Hi Guys!

I am having a hell of an issue that I can’t figure out. We hooked up the API without having an SSL. Then, since we are embedding the checkout on a specific channel (www.neckenvy.com), we hooked up the SSL, and all the urls were updated, but the backend code that allows to embedd seems to be stuck on HTTP. I have no clue how to change that and our checkout right now is just an empty page. See screenshot: https://prnt.sc/myxv0r

If anyone can help, thank you so much!!
