Configuring Provisions and WHMCS

I’m trying to setup WP Provisions with WHMCS and can register with my WHMCS setup. However, even though it is supposed to setup a new account automatically it sends it to pending.

When I try to activate it manually, I get this error:

Connection Error: 6 – Couldn’t resolve host ‘http’

What am I missing here? I have gone through the Provisions install instructions multiple times.
