10.3 and 3.1 Plug'nPay Transactions Not Being Authorized, No Reason Code
Problem
PlugNPay is returning the following error whenever a credit card is processed:
'Transaction was not Authorized...'
Reason: '
No reason is specified. What is this error and how can it be resolved. Credit Card cannot be processed with this error.
Solution
This is typically the result of PlugNPay's inability to communicate with your server using port 443. To resolve this, VSI recommends you open port 443 fully for incoming and outgoing traffic.
However, if this is not possible or if you use an IP filter, then you be sure to allow connections to port 443 from the following IP addresses, which are owed by PlugNPay:
Server IPs:
209.51.176.0 to 209.51.176.255
206.25.10.0 to 206.25.10.255
209.51.163.240 to 209.51.163.255
209.51.171.150 to 209.51.171.158
96.56.10.14
69.18.198.4
The above IP addresses belong to and are used by PlugNPay. Their servers and office workstations use these IP addresses. Setting up your system to allow access from these IP addresses will prevent transaction not authorized failures as PlugNPay add/move servers and/or extend their system's abilities.
