The transaction could not be submitted or processed due to temporary issues, invalid data, or transmission errors. This is typically a transient error that may resolve on retry.

## Recommended Customer Message

There is a temporary problem with your submission. Please try submitting the transaction again.

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

-   **Temporary gateway processing issues:** The payment processor experiences momentary disruptions affecting transaction submissions.
-   **Invalid or incomplete submission payload:** Data required for processing is missing or incorrectly structured.
-   **Timeouts or transmission errors:** Network delays or interruptions during transaction submission.
-   **System maintenance:** The payment gateway is undergoing scheduled maintenance, affecting transaction processing.

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