Hello starbeads,
Thank you for dropping by here in the Community. Allow me to step in and help get rid of the error message when connecting your bank in QuickBooks Online.
Since you're unable to locate any error message from the website, I recommend contacting your Bank Customer Service. One of them will need to check your account and make sure there's no pending message that need's your response.
After getting confirmation, if you continue to get the error message, it would be best to reach out to our Support Specialists this time. They'll need to take over and perform further troubleshooting on your behalf.
You can reach them through these steps:
- Log into your QuickBooks account.
- Click the Help option in the upper-right corner.
- Click the Contact us hyperlink.
For future reference in case you're unable to download bank transactions, you can visit this article:

As always, let me know for any additional questions you may concerning your Bank Feeds. The Community will be sure to get back to you.
