**gateway**

The payment method is in an unexpected state. This can happen when the payment method is not in a valid state for processing, a previous transaction was interrupted, or the gateway encountered an unexpected condition. Contact your payment gateway support if the problem persists.

## Recommended Customer Message

Your payment cannot be processed due to an unexpected issue. Try again or contact support for help.

## Root Cause[](#root-cause)

-   **Invalid payment method state:** The payment method is not in a valid state for processing transactions.
-   **Interrupted previous transactions:** Incomplete or interrupted prior transactions left the payment method in an inconsistent state.
-   **Temporary gateway issue:** The payment gateway encountered an unexpected state while processing the transaction.
-   **Gateway integration errors:** Incorrect API request sequence or invalid state transitions in the payment flow.

## Troubleshooting and Solutions[](#troubleshooting-and-solutions)

-   Ask the customer to retry the transaction after a short interval.
-   Verify the payment method is active and correctly set up for processing.
-   If the issue persists, ask the customer to add the payment method again before retrying.
-   Contact the payment gateway support team if the issue persists across multiple attempts.
