Why was the transaction declined?

There are several reasons for a rejected transaction. The most common are: 

1. Transaction not confirmed with 3D secure.
2. Not enough money on the card. 
3. Payment was refused by the buyer's bank. 
4. The transaction was considered a risk / attempted fraud. 
5. Unknown reasons. 

If multiple payments have been rejected by different buyers, please check the status of your payment provider. Especially whether payments are active.
