    An HTTP code 400 is, actually, an internet error (as evidenced by the HTTP prefix).
    It means that the website that you were trying to connect to can't be found.

    SO, what exactly were you trying to do when this happened?  And, for what bank/card/etc did this error happen?

  • I wish I could tell you which one of my accounts is causing the problem. I have no trouble downloading the bank and credit card info into quicken itself.
    This issue with the HTTP-400 error happens every time I try to "SYNC" to the cloud.

    Please verify these settings:

    Go into Control Panel / Internet Options
    Start Internet Explorer. Click on Tools / Internet options.

    Click the Advanced tab.

    Ensure that all "Use TLS 1.0, 1.1, 1.2" have checkmarks.
    Uncheck all "Use SSL x.x"
    Click the Contents tab and click the "Clear SSL state" button.
    Click Apply, then OK.
    Close IE.
    Close and restart Quicken and see what happens.

    But that might not resolve any issues that Quicken has with not being able to access the Internet. Double-check your Firewall / Antivirus settings to ensure that the Quicken program (C:\[full and correct path name here]\qw.exe) always has permission to establish outbound Internet connections.
    If your AV / Firewall software creates log files, please review them, if necessary with the help of your AV software support team. That might show the problem and give you a way to easily resolve it.
