Zoho not able to send outgoing gmail from Zoho Desktop

I am unable to send outgoing emails from my linked gmail account from the desktop application.  The outgoing works fine on the zoho app but not on the desktop.  I am attaching a screenshot showing the "Bad Credentials" message.  I have reset my password, reset the port settings and still am unable to get emails to go out from Zoho.  Please advise.
