Troubleshooting Payment Decline (Error Code 491) 💡 Quick Summary: Error 491 is a card security decline. It happens because our payment gateway uses 3D Secure (3DS) and requires 2-Factor Authentication (OTP). 🔍 Detailed Guidance The Gateway: Payments on our portal are processed through Cybersource (owned by Visa), requiring strict security checks to block malicious bots. The Solution: Try checking out with an alternative card that has 3D Secure / OTP enabled. If your international bank blocks the transaction, you may need to call them to authorize a payment to Sri Lanka. ⚠️ Critical Alerts & Requirements Charged but No Pass? If your card was charged but you did not receive your pass due to a page timeout, email info@thepekoetrailsrilanka.com with your payment receipt PDF, registered email, and the stage date.
