    Hello Nadine,

    I did test your form and I am unable to replicate the issue you are having. I was successfully redirected to PayPal checkout page. Please check the screenshot below:


    Have you embedded your form in any webpage where you are having this issue with? Please share the webpage URL and we will take a look.

    We will wait for your response.

    Thank you!

    Hello Nadine,

    This also happens if you use PayPal over VPN or Proxy. This is pretty common in workplaces.

    Thank you
