I can help you resolve the error to connect your bank account successfully, lee.
Can you tell us what bank are you trying to connect to QuickBooks and the error code you're encountering? This is to check if there's an ongoing issue with it and verify what exact error you're having.
Then, let's try to check if the bank is successfully connected if you're going to log in using a web browser. Here's the login page for QuickBooks Online: https://qbo.intuit.com/login. This is to isolate if you're only having this error from the mobile app.
If you're having an error both in the web and mobile app, here's an article on how to fix it: What
to do if bank transactions won’t download and go to Step 3: Fix specific banking errors.
