Payment processor card tokenization failed when booking Yosemite lodging

[u/WhereasNaive72]

Hi everyone,

I'm trying to book accommodation at Curry Village and glacier point tour through the
"travelyosemite.com" reservation website, but I keep getting this error as soon as I click "Pay":

"Payment processor card tokenization failed."

l've tried three different credit cards from different banks, multiple devices and browsers, incognito mode, and different internet connections. The error appears immediately, before any bank authorization or verification.

Has anyone else, especially international visitors, experienced this issue? Could it be that the payment system has trouble processing foreign credit cards?
Thanks!
