How to use One Step Update to download transactions from Capital One credit card account? (CC-555 error)

Until about five days ago, One Step Update worked just fine in downloading transactions from my Capital One credit card.  Now I get error message CC-555, indicating that Quicken believes that Capital One's servers are denying access to Quicken.

Capital One tech support says they've made no change to their software, so they suggest contacting Intuit.  They think Intuit has made a software change.  They've heard the problem from other cardholders who use Quicken.

Note that I can visit the Capital One website and can successfully download the transactions in QXF format.  But I want One Step Update to work, since this is only one of about 20 diffferent accounts.

I have already tried the standard trick of deactivating One Step Update for the Capital One account, and then tried to reactivate it.  No luck.  Same error message.

Anyone else having this problem?  

Intuit, if you are listening, have you reached out to Capital One's tech people?
  • It  is 1/1/13 would think this issue is would be fixed.  Have not done finances for awhile.  Got the error message on download.  Prior to researching tried to disconnect and resetup.  Now when try to setup Quicken states it can not find Capital One Bank.  The bank web page states all downloads must be in started in quicken.  You can no longer download to Quicken from the bank's web page.  If you read Capital One's FAQ they state both methods still work.

    Was getting an error message originally before I disconnected the account.  I know can't get the account to connect.  The web address I use if I want to see the account online is  Capital One is not listed so I selected "Capital One Bank".  It is a checking account.
  • Capital One suffered a denial of service attack about three months ago, it has been resolved and I have been downloading successfully from my Cap One Bank savings account and my Cap One Card Services credit card account via Quicken's One-Step Update. Which error message code are you getting and have you reached out to Quicken support for help?
This issue is not due to a bug.  Support staff on both sides (CapOne & Quicken) may fail to understand what DDoS is, and make a statement that's not accurate.  Distributed Denial of Service attempts to make systems unavailable to users by keeping them too busy to handle other requests - basically, they flood the servers with traffic.  This is not a bug, and it's not a hack or virus.  A large number of US financial institutions have been the target of these DDoS attacks in recent weeks/months.

Capital One has requested we stop aggregation while these server issues get sorted out.  Server teams from both sides (Intuit & Capital One) are working together to get the service back on for our mutual customers.

We have posted a Containment article on the Quicken Support site - - where you can sign up for an email notification when the temporary block has been lifted.

Until then you will continue to receive CC-555 (Quicken Windows) or Error 155 (Quicken Essentials Mac) advising that the FI is blocking our access.
  • Having same problem. They did list on the Quicken contact page that this was a know problem but as of today it was removed, however I still could not connect. I deactivated my Capital One account and tried to reactivate when this first happened not knowing this could further complicate things.
  • I was just able to successfully update my Capital One account using one-step update. Ok for now......
  • I have had this problem for many days and still have it.  I look forward to receiving an email that this has been resolved.
Yes we have been actively working with Cap One OFX engineering since they contacted us about this a couple of weeks ago. There isn't anything that we can do but wait.  Cap One support may not be aware of it this, but should also know the difference between server issues and software issues.

This is a server issue.  Capital One has been experiencing some extremely high volume of server traffic and has blocked our aggregation off and on for the past couple of weeks while they sort things out.

FYI - do NOT deactivate and reactivate your accounts unless expressly advised to do so by help documentation.  Doing so may cause you to be unable ato reactivate when the error is due to denial of service (blocking), however temporary, and put your account into a "dead" state.  The only way out of that is to start a new account in your existing Quicken file.  And you're already using the prescribed temporary solution for updating accounts during a server block/outage.
  • I am having the same experience. Howver, having spoken to Capital One and also seeing the Intuit response, I'm not sure when this ever gets fixed since both sides seem to be pointing the finger at one another.
  • I called Capital One, and they said they will no longer be supporting the one-click update due to security reasons. This feature was disabled during their lost DDOS attack, and will no longer be enabled.
  • That's disappointing, that they've apparently given up on One Step Update.  I wonder if Intuit is doing anything to allay their fears about security.
  • The head scratcher for me is that Capital One Bank (online savings) is working just fine. Why should it be any different for the credit card side? Doesn't make sense.
  • I too am blocked from Capital One with this error. If its not resolved I may just have to go to another credit card..Don't they care?
  • Just talked to Capital One..They said its their problem..they're working it, but no ETA for solution....
  • Having the same problem. I was told by Capital One that Quicken "has a bug" and they (Cap 1)are preventing downloads till it is fixed and I should contact Quicken.  So how long is THIS expected to go on??
