    Umbraco login is not working

    I'm having an issue with Umbraco 7.14 with which I can't login to the Umbraco in new server and I receive the message "Login failed for user ". Using developers tools I also get the error "Failed to load resource: the server responded with a status of 403 /umbraco/backoffice/UmbracoApi/Authentication/PostLogin 403..

    Hi Priya,

    You probably tried to login with the wrong password too many times and umbraco locked you out.

    To fix this go to the database, open umbracoUser table and update userNoConsole to 0 for your username.

    Otherwise ,Please have a look on this thread https://our.umbraco.com/forum/umbraco-7/using-umbraco-7/50407-Login-failed-for-user-in-Umbraco-7

    Regards Dhanesh :)

    Hi Priya,

    If https://our.umbraco.com/forum/umbraco-7/using-umbraco-7/50407-Login-failed-for-user-in-Umbraco-7 this doesn't help

    Then please do a fresh install and migrate the content from old one to new one using Usync.

    Regards Dhanesh :)

    Did the machine key in the web.config change for any reason? Back office uses the machine key and the decryption key to encrypt and decrypt user passwords. If this has changed for some reason then you won’t be able to login. Also check whether other users can login.

    Hello Angelo,

    In my case as I'm using Plesk Control panel.

    The below changes fixed the issue.

    Go to Tools & Settings > Web Application Firewall (ModSecurity) (in the Security group).

    Set the web application firewall mode to Off or Detection only accordingly.

    Let me know if that worked.

    Regards

    Param

    Hi Angelo,

    I’m glad it worked out!

    Actually, this Web Application Firewall (ModSecurity) is to prevent attacks and secure the web applications, so it verifies all requests from the server.

    When it is set to - On the predefined rulesets prevents the UmbracoAPI requests and other authentication related requests which causes the issue.

    Regards

    Param
