Cause

Misconfiguration of the FTP websites and FTP users.

Resolution

1. Log into the server via RDP.
2. Execute the following command via the command line:

   C:\> plesk repair ftp -y

   Note: There is a probability, that the issue is resolved completely by this command. Check FTP access once again. In case the issue will persist, proceed further with the resolution.

3. Execute the following command via the command line in order to re-create FTP site in IIS:

   C:\> "%plesk_cli%\repair.exe" --reconfigure-ftp-site -webspace-name example.com

4. Execute the following command in order to re-create missing FTP users if any:

   C:\> "%plesk_cli%\repair" --repair-webspace-system-users -webspace-name example.com

If it is needed to re-configure all websites, do the following:

1. Log into the server via RDP.
2. Retrieve a list of all domains with hosting. Replace the *** symbols with your Plesk admin password:

   C:\> "%plesk_dir%"\MySQL\bin\mysql.exe -uadmin -p*** -P8306 psa -Ne"select name from domains where htype='vrt_hst'" > C:\domains.txt

3. Change your directory to %plesk_cli%

   C:\> cd %plesk_cli%

4. Execute the repair.exe utility for each domain:

   C:\> for /f "tokens=*" %d in ('type C:\domains.txt') do repair.exe --reconfigure-ftp-site -webspace-name %d
