When using your web widget in staging mode and choosing PayPal payment, it seems to call (or redirect to) https://sandbox.paypal.com/cgi-bin/webscr.
However, one cannot connect to that site because there's an SSL error. The certificate is only valid for www.sandbox.paypal.com, so one must probably just add a www. at the beginning of the host to make this work again.
