Assistance Required: Authentication Error When Sending Credit Application Form

Hi,

I'm encountering an error message that states: "Authentication unsuccessful – the user credentials were incorrect."

This occurs when I attempt to send the credit application form to our customers. I've attached the form I’m trying to send for your reference.

Could you please advise on how to resolve this issue?

Your prompt assistance would be greatly appreciated.
