| **Error Message**         | An error occurred in the financial institution connection. Submitting a support ticket is the recommended action.                                                                                                                                                                                                                                                                                                                                                                                      |
| **Common Causes**         | This error usually happens when the bank updates its website or server. These changes can disrupt the connection between your app and the bank, requiring changes/updates to restore the original connection.                                                                                                                                                                                                                                                                                          |
| **Troubleshooting Steps** | Submit a [support ticket](https://developer.mastercard.com/open-finance-us/documentation/support/index.md#create-a-support-case-in-scm) for troubleshooting. ​Simultaneously, Data Connect display alerts will automatically prompt the end user when they are in session to take suggested remediation action associated with this error. ​Best Practice: Developers may prompt the end users to log into their application to ensure the end users can take recommended action to resolve the issue. |
| **Retriable by End User** | Yes, the end user will need to make 3-5 authentication attempts which will assist in the troubleshooting process. ​                                                                                                                                                                                                                                                                                                                                                                                    |
| **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.                                                                                                                                                                                                                                                                                                                                                                                            |
