This morning, I'm getting error CC-503 "Oops. Did you mistype your login?" when trying to perform a one step update with my Sallie Mae account. I tried to reset the account to see if that would correct the problem, and the error came up again so had to cancel and now the account connection is terminated. My credentials or account information have not changed with the bank. There are NO non-allowed special characters used e.g. ampersand (&), left carat (<), right carat (>), backslash (), and forward slash (/).
