I've tried Chrome, FireFox, even used Edge. They all do the same thing. Click the "Replace Key" button. Popup comes up. Shows the correct server. Auto closes. Nothing in the main window now happens. Before there was a "finish replacement" button that just opened the same popup again.
I don't see the point of this. All the right server details are there. Its the original key from nearly 5 years ago. USB drive has never been changed.
This is the most frustrating key replacement I've ever done.
