QuickBooks has recently updated its connections with various banks for improving efficiency and reliability of the services. Major Banks like Chase, Bank of America, Wells Fargo, Citi Bank, and Capital One have already accepted the new connection method QuickBooks is using to connect with them. If you have not reconnected your account in QuickBooks after this recent update, then you might encounter QuickBooks error 377 in your QuickBooks Online application. You need to click the Update Now button in the notification banner for establishing a new connection with your bank.
