All i can think of is that your card might be disabled for buying overseas/website products, you need to telephone your bank to enable it.

Or insufficient fund?

By the way my local banks called us to change our signature-based to PIN-based debit card for free since May~June 2016. Signature-based debit card is still usable but will be unable to make transaction after 18 December 2016 (many of us last minute change our debit card lmao). I'm not sure whether this is applicable to you or not.
