HTTP-400 when syncing to web

a.ertel Member

Every time I try to sync to the Web, using the "sync now" button in the "Mobile and Web" tab (Quicken for windows), I get and error message that says "Quicken encountered a client side error while syncing your data [HTTP-400]. This has been for more than a week and I have tried many times.

Any suggestions or solutions?

    Hello @a.ertel,

    Thank you for reaching out to the Community and telling us about this issue.  I'm sorry to hear you're running into this problem. First, I would recommend you try logging out of Quicken, then logging back in. To do that, go to Edit>Preferences>Quicken ID & Cloud Accounts. Click on the blue link that says Sign in as a different user.

    When the confirmation box comes up, type "yes", then click Sign Out. Quicken will log you out and bring you back to the login screen. Login using your Quicken ID and password.

    Thank you.
