Error 108 simply means there's a message on your bank or financial institution's (FI) website that requires action from you. Sign in to your bank or FI's website and either dismiss or act on all notifications. 

Here are some examples:
  • New terms of service
  • An announcement regarding maintenance or other site changes
  • A new offer 
If you don't see a notification, you may need to disable your pop-up blocker. 

Once you acknowledge all messages, return to QuickBooks and select Update from the Banking page.
