Here are the possible reasons why you're unable to connect your bank feeds to the program:
1. A problem at your bank.
2. An issue with your Internet connection.
3. A discontinued version of Windows or Quickbooks.
After updating your QuickBooks, most banks need identity confirmation before accessing data from QuickBooks. You’ll need to log in to your account outside the program and check your Notification inbox for details.
