I am unable to connect my Paypal account in the form

Hi for some reason I am unable to connect my Paypal account to receive payments on one of my forms. It keeps saying that it has failed. 

Please refer to the following guide for our Paypal Checkout Integration:

https://www.jotform.com/help/542-How-to-integrate-PayPal-Checkout-with-your-form

Please check the popup after you log in your Paypal account. The following should be displayed and the blue button that says to go back Jotform should be clicked.
