Unfortunatelly there is no detailed error message, but found detailed informations in the browser network traffic:
[Payment Service] Setting application error state,{"status":400,"data":{"type":"CS_WEB_SERVICE_478","title":"UCO_CC_ERROR_FROM_CS",
"detail":"We are unable to authorize payment. Please contact your issuing bank or provide another credit card or an alternative form of payment (Error Code 478)."
}}
All bank card and payment requirements are met and I registered with the same bank card and data!
