| **Error Message**           | An error occurred in the financial institution connection.                                                                                                                                                                                                                                                                                                                                                                                                                                             |
| **Common Causes**           | For security reasons, we could not connect to the end user's selected account at this time.​ There can be several reasons: * Information provided during authentication is either incomplete or insufficient to link an account and access data * Incorrect response to security questions, for example, incorrect security code or an expired security code due to time lapse.                                                                                                                        |
| **Troubleshooting Steps**   | * Submit a [support ticket](https://developer.mastercard.com/open-finance-au/documentation/support/index.md#create-a-support-case-in-scm) for troubleshooting. Simultaneously, 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 end users to log into their application to ensure end users can take timely recommended action so that data access/refresh can be resumed. |
| **Retriable by End User**   | Yes, the end user will be able to resume session, once connection to the selected financial institutions is fixed. May need to make several authentication attempts to assist in resolving the error. ​                                                                                                                                                                                                                                                                                                |
| **Access to Latest Data**   | Yes, data refresh will be skipped until the issue is resolved.                                                                                                                                                                                                                                                                                                                                                                                                                                         |
