Pro Sites not working

I was on a live chat with Huberson Dorvilus but got cut off. I have unlocked support access to my network.

When you got to the pro sites url: and you try to register with test stripe details ( nothing happens. It registers the user but not the site. And there are no success or error messages. I have WP_DEBUG and WP_DEBUG_LOG set to true and WP_DEBUG_DISPLAY set to false but there is nothing there.

Stripe records the API calls but no transactions are going through.
