Thank you for getting back to us,@Paying Customer.

I understand you want to save time from contacting support and try another workaround instead of disconnecting your bank account from QuickBooks Desktop.

I appreciate you trying to perform troubleshooting steps to resolve the issue. Since you're still getting the same error, I recommend contacting our support team. This way, they can access your account in a secure environment. 

The steps provided by my colleague above are a request for a callback. You don't have to wait in the queue.

Additionally, you can check how to disconnect bank feeds in QuickBooks Desktop for more information.

Let me know if you have any other questions or concerns about bank connectivity. The Community and our support team will always be here to lend an extra hand. Take care and have a good day.
