Hi. I had the same problem. I run Windows 10, and tried everything in Edge, Chrome, Firefox, and Brave browsers. I even disabled all security features and firewalls in various places. Nothing worked. But, I tried it on my iPhone 8, in Safari. Just log in, and pay, it worked. Then I went back to Windows, Edge, and finished doing all the other tasks. So, if you're completely stuck - go to Safari on an iphone to pay. Maybe it will work on other phones, maybe other machines.
