If you receive the message "We couldn't add your ticket" when trying to link your ticket, there are a few possible causes.
Ticket barcode invalid
Make sure the ticket number was entered correctly. You can ignore spaces when typing.
You might have opened the Eventportal for a different event or a previous year.
You might have accidentally entered your order number. Please use the ticket number printed below the barcode or QR code of your ticket.
Ticket already linked
Verify whether you were previously logged into the Eventportal with another account or if someone you know has already linked this ticket. You can release a linked ticket by clicking the "Remove Wallet" button.
Ticket type cannot be linked
Additional tickets, such as upgrades, parking, or camping add-ons, cannot be linked and therefore cannot be used to top up the balance in advance. Link your main ticket instead.
