Troubleshooting the FTP error in Plesk for Windows Server: User cannot log in, home directory inaccessible

    In my case, the 503 FTP problem was due to another additionnal cause, caused by Plesk however.

    The 503 FTP problem appeared after I restored a subscription from a Plesk Backup.

    As all the solutions listed on this page did not succeed, I went to "Computer Management > Users and Groups" (I am running a Windows 2012 R2 Web Server).

    I discovered that the user account in charge of running the for service for this website was "DISABLED" !

    Obviously, I re-enabled this user, and Boom : The FTP access was available anew, solving and vanishing the 503 FTP error.


    The cause is that this user account was disabled by Plesk while restoring the backup, then Plesk forgot to re-enable it.

    I am not sure if this issue will appear wether you check or do not check the "Disable website while restoring from backup" on the Plesk panel).

    I hope that this issue was solved in Plesk Onyx. This happened to me in Plesk 12.5 latest update at time of writing (25th, Novembre, 2018).

    Fo what it worth, I am sure this comment will help some of you, folks ;)
