Barclays Online Banking - cannot add account since May 15, 2026

Question

I have been unable to add a Barclays Online Banking account to Quicken since approximately May 15, 2026.

When I try to add the account, I receive CC-503.

I have already had two support sessions with Quicken. During both sessions, support collected diagnostic data and filed an escalation. My Barclays username and password are correct and were verified during the support sessions.

An interesting part of the problem is that downloads for Barclays accounts that were already connected before May continue to work correctly. The problem occurs only when trying to add a new Barclays account.

Also, if I deactivate an existing Barclays account, I cannot add/reactivate it afterward because the connection attempt results in CC-503.

So, at this point:

* Existing Barclays accounts connected before May - downloads work.
* Adding a Barclays account - CC-503.
* Deactivating an existing account and trying to reconnect it - CC-503.

This issue has persisted for more than three months despite two escalations to Quicken Support.

Is anyone else experiencing the same problem with Barclays Online Banking?

Please describe the exact name and/or type of Barclays account that you have. A review of the list of supported financial institutions (fidir.txt file) finds a number of Barclays-sponsored credit cards, each of them with their own financial institution name … so, depending on the name on the card, you may have to activate your card accounts using a different, separate name than the generic Barclays entry on file.

Thank you for your response.

I have already completed all of the steps in the support article, both by myself and during two separate sessions with Quicken Support.

In particular, the last troubleshooting step in the article—deactivating the accounts—is how I ended up with my previously connected Barclays accounts disconnected. Unfortunately, once deactivated, they cannot be added back because the same CC-503 error occurs.

During my support sessions, it was also verified that I am using the correct Barclays login credentials. Before deactivation, downloads for the Barclays accounts that had been connected before approximately May 15, 2026 were working correctly. The problem is specifically with adding or re-adding a Barclays account.

Both Quicken Support sessions ended with diagnostic data being collected and the issue being escalated.

So my main question is not how to troubleshoot CC-503—I have already gone through that process multiple times.

My real question is: Am I the only Quicken user currently unable to add or re-add a Barclays Bank account, or is this a known/wider issue affecting other users as well?

Hello @Zeka,

I know this can be frustrating that you have been trying for 3 months to connect your Barclays Bank account. A CC-503 error occurs when your financial institution tells Quicken that your login credentials are incorrect.

With this error that you are receiving we do have a support article for the steps to try to fix the issue.

Due to the nature of this issue, if the error continues it is recommended that you contact Quicken Support directly for further assistance, as they can walk you through troubleshooting steps in real-time and escalate the situation as needed. The Quicken Support phone number can be found through this link here. Phone support is available from 5:00 am PT to 5:00 pm PT, Monday through Friday. I apologize that I could not be of more assistance!

Thank you.
