CC-503 Error with Bank of Nova Scotia. Worked up until Sept 15, 2025

Hello @Russ Grabowski,

We appreciate you letting us know about this issue! I understand how frustrating it can be when your accounts stop connecting, especially after everything was working smoothly.

Please review and follow this support article regarding this error.

A CC-503 error generally occurs when your bank indicates that your login credentials are incorrect. This can happen even if your password hasn’t changed, for example if the bank updated security settings, requires additional verification for third-party apps, or if special characters in your password are causing a login issue.

It’s a good idea to verify your login directly on the bank’s website and ensure that Quicken is using the exact credentials recognized by the bank. If the issue persists after confirming your credentials, the support article suggests options like updating or resetting your password in Quicken, or deactivating/reactivating the account.

If none of these resolve the connection, the please reach out to Quicken Support directly. Our support agents will need to review your account logs and escalate if needed.

Thank you!

Thanks for the update! Glad to hear that worked for you.
