CITI Bank Online CC-503 since 10/14/2025

Question

I'm running Quicken Classic Deluxe version R64.30 for Windows.

Quicken offers two links to add bank accounts at www.cit.com:

1) CIT Bank N.A New Login

2) CIT Bank Online.

Both options return error CC-503 when trying to Add Account.

I first encountered this issue on 10/14/2025. The CIT Bank Online login credentials I'm entering in Quicken are correct

Is anyone else having this issue?

As I stated above, "The CIT Bank Online login credentials I'm entering in Quicken are correct." A Quicken support tech watched me successfully log in to my CIT account at www.cit.com by using the very same credentials that are triggering the CC-503 error.

The Quicken support tech also observed that error CC-503 is returned whether I use CIT Bank N.A New Login or CIT Bank Online.

Quicken support has not resolved this issue.

Hello @Dsipname2,

Thank you for taking the time to share these details. The CC-503 error you’re encountering indicates that the financial institution is returning an “invalid credentials” response when Quicken attempts to connect.

I recommend reviewing this support article for more information on what this error means and what steps can help resolve it.

The article covers possible causes—such as a recent password change, temporary bank security prompts, or selecting the wrong instance of the bank (for example, CIT Bank N.A. New Login vs. CIT Bank Online).

If the issue persists after following the article, then we advise that you please contact Quicken Support directly for further assistance and possible escalation.

Thank you!
