Unable to connect my NAB bank to quickbooks

Could you provide the specific error code or message you encounter when trying to connect to National Australia Bank? In the meantime, log in directly to your bank's website to check for any service updates, security prompts, or maintenance alerts that may require your attention. Please also ensure that the bank login credentials you're entering into QuickBooks are correct.

As a workaround, if you need to categorize transactions immediately, you can manually upload your bank transactions using a CSV file. Once your bank feed is connected and working, remember to exclude any duplicate transactions.

Feel free to return if you have follow-up questions.
