I can see how vital it is for you to connect your banks to QuickBooks, carrxpert. I’m here to provide insight into the error you’ve encountered and help you manage your transactions in QuickBooks effectively.
Bank error 155 occurs when your bank prevents QuickBooks from connecting and retrieving your data. This issue usually resolves itself once your financial institution allows a connection with QuickBooks.
To address the error message, I recommend contacting your bank and requesting them to enable connectivity with QuickBooks. If the problem continues, please ask the bank’s representative to elevate the matter through our OFX Connectivity page for a resolution. Ensure to take note of your case or ticket number for future reference.
