| **Error Message**             | Temporary connection issue for the financial institution. Wait a few minutes and try again.

| **Common Causes**             | Connection is interrupted temporarily due to an unexpected error. It is possible that during the add account process via Connect an error occurred in the financial institution connection. ​For already added accounts this means that the customer's account information has changed at the financial institution or user account data has mismatch. This indicates an issue with duplicate accounts. The end user has two accounts that appears to be the same in the returned data. |
