| **Error Message**             | An error occurred in the financial institution connection. Submitting a [support ticket](https://developer.mastercard.com/open-finance-us/documentation/support/index.md#create-a-support-case-in-scm) is the recommended action.​                                                                                           |
| **Common Causes**             | Connection is interrupted temporarily due to an unexpected error.
