I received an error with "Payment Failed - Gateway error. IO Exception: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 503 Service Unavailable". What does it mean?
This error means that the payment gateway is having diffculties linking to the bank to complete the transaction.
This can be caused if the the payers bank is having technical issues from their end eg: the bank is down.
Payments2Us goes back to recheck these txns four times a day (every six hours). If the next attempt of the txn is successful, the Status will go to
Confirmed - Checked ------Matching Complete. If the next attempt successfully links to the bank, but it is a bad txn eg: insufficient funds, do not honour, etc, the status will change to Error - Checked.
