HPS Gateway Error 2 | Solutions to Fix

HPS Gateway Error 2 typically refers to a transaction decline or authorization problem in a payment gateway context.

Specifically, error code “2” is commonly interpreted as an authorization response error, indicating that the transaction was declined due to issues related to the card, its limits, or authorization requirements.​

Causes

• Cardholder has exceeded daily credit limits or number of uses.​

• The issuer may need confirmation that the cardholder is in possession of the card (security measure).​

• General authorization failure due to card settings or limits.​

Solutions

• Ask the customer to contact their card issuer for more information or to address the issue.

• Suggest trying a different payment method if possible.

• Reattempt the transaction after confirming that all entered details (card number, expiration date, CVV) are accurate and the card has not reached usage limits.​

When to Escalate

• If multiple valid transactions are declined consistently.

• If the error persists after checking card details and limits.

This error is not typically related to technical faults in the gateway system, but rather authorization and cardholder validation by the issuing bank.

How to retrieve HPS gateway logs for Error 2

To retrieve HPS (or similar enterprise/payment/on-premises/data) gateway logs for troubleshooting Error 2, follow these general steps:

For Kubernetes-based Gateway Installations

• Get the pod name with:
  kubectl get pods -A

• List containers in the gateway pod:
  kubectl get pod <pod name> -o="custom-columns=NAME:.metadata.name,CONTAINERS:.spec.containers[*].name"

• Fetch logs for a specific container (replace <pod name> and <container name>):
  kubectl logs <pod name> --container <container name> -f

Separate containers may manage key functions (e.g., vprobe for connectivity, postgres for persistence); fetch their logs as needed for targeted diagnosis.​

For On-Premises Data Gateway (Windows)

• Open the gateway app, go to Diagnostics, and use Export logs to save log files (typically as a .zip on your desktop).

• To access Windows Event Logs, open Event Viewer, expand Applications and Services Logs, and select On-premises data gateway service.​

• Log files may also reside in directories like %localappdata%\Microsoft\On-premises Data Gateway.​

For SAP Gateway

• Use transaction codes:

  • /IWFND/ERROR_LOG (Gateway Hub)

  • /IWBEP/ERROR_LOG (Back-end Server)

• Filter by user, time, and date, then execute to display relevant errors.​​

For AWS API Gateway

• Enable and review CloudWatch logs for the API Gateway stage you are concerned with.​

Logs will help identify the request responsible for Error 2, allowing you to analyze the error context, involved endpoints, and trace back authorization or card-related issues commonly linked with this error code. Always reference your gateway’s product documentation for the most targeted log retrieval approach.
