"Page www. ... .com does not work" when Submlitting Event Registration Webform for immediate On-line Payment
Webform CiviCRM works great with a number of Payment Processors! Especially those that process in-line (e.g. PayPal Pro and iATS Payments - Credit/Debit) - if you want to use https://civicrm.org/extensions/cm-cic-payment you'll have to check in with the Author for it - to see why this is not working for you. 

I'm guessing CM-CIC may have a Payment Page? Then that will not work - you need an in-line payment processor.
