CC-800 error - Alliant Credit Union [Edited]

DRWendte

I'm running Quicken Classic using Windows 11. I have an Alliant Credit Union share account and an Alliant Credit Union Visa credit card. Every day for over two weeks, I have been receiving error messages when I've tried to run an update summary on these two accounts. I've attached a screenshot of the error message I receive. The message says the accounts have been deleted; they have not.

I have several times deactivated the download for Alliant and then re-established the online connection, but that has never been successful. I still get the error message when I try to update my Alliant Credit Union accounts. I have also several times "Reset" the accounts, but that has also proved fruitless. Any assistance would be appreciated.
