CIT Bank cc-503

I'm running Quicken Classic Premier R65.29 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 an Account.

I first encountered this issue sometime in late October to early November. The CIT Bank Online login credentials I'm entering in Quicken are correct. I have verified them by going directly to CIT Bank's website and logged in without issue. I even tried changing my password with the same results.

Is anyone else having this issue or have you found a solution?

Thanks in advance
