| **Data Connect Alert**        | An unexpected exception error has occurred while logging in. Try again later. If this error persists, contact your administrator.

| **Error Message**             | There are currently too many connections to the financial institution for the customer. It may help to have the customer log out of the financial institution website on any device they have it open on. Otherwise, have them try again later when the additional connections have dropped automatically. If the issue persists, submitting a support ticket is the recommended action. |
| **Common Causes**             | This error can happen for the following reasons: * If the user is trying to log in multiple times simultaneously, for example, if the user is already logged into their bank account, which then rejects a second login attempt. * Mismatch in account information as entered by the end user and what is available at the financial institution.                                        |
| **Troubleshooting Steps**     | Submit a [support ticket](https://developer.mastercard.com/open-finance-us/documentation/support/index.md#create-a-support-case-in-scm).                                                                                                                                                                                                                                                 |
