Why do I keep getting Error Code U521 on Ticketmaster?

• There may be server issues such as outages, overloading, or the website is being updated.
• Your payment method (service) was not accepted due to insufficient funds.

• Ensure you’re buying tickets from a legitimate online platform – There are a lot of sites masquerading as the real thing, so always double-check the URL to ensure you’re not being catfished.
• Double-check payment method before submitting transaction – Before checkout, check whether you have sufficient funds to make the purchase and your credentials match your debit/credit card.
• Disable third-party extensions – Extensions, especially adblockers, prevent sites like Ticketmaster from loading properly and may keep popping up the Pardon for the interruption error message.
