| **Error Message**             | End user must refresh accounts and answer OTP every time they want updated data.                                                                                                                                                                                                                                                                                                                                                                                                                         |
| **Common Causes**             | For security reasons, we could not connect to the end user's selected account at this time.​ Information provided during authentication is either incomplete or insufficient to link an account and access data. For example, incorrect response to security questions, such as incorrect security code or an expired security code due to time lapse.                                                                                                                                                   |
| **Troubleshooting Steps**     | * Data Connect alerts will automatically prompt the end user when they are in a session to take suggested remediation action on your behalf. * Best Practice: Developers may prompt the end users to log into their application to ensure the end users can take timely recommended action so that data access/refresh can be resumed. * If the issue persists, submit a [support ticket](https://developer.mastercard.com/open-finance-us/documentation/support/index.md#create-a-support-case-in-scm). |
| **Data Connect Fix Eligible** | No.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      |
| **Retriable by End User**     | Yes, the end user will be able to resume the session, once the connection to the selected financial institution is fixed. The end user may need to make several authentication attempts to assist in resolving the error. ​                                                                                                                                                                                                                                                                              |
| **Access to Latest Data**     | You will be unable to access the latest data for this user's account until the end user resolves the issue.​                                                                                                                                                                                                                                                                                                                                                                                             |
