PHP-FPM is set as a PHP handler at Plesk > Domains > example.com > PHP Settings.
This is a Plesk bug #PPPM-10717 that will be fixed in future product updates.
Until the bug is fixed, use the following workaround:
Go to Domains > example.com > PHP Settings and switch the PHP handler from FPM to any with CGI/FastCGI support.
Note: If only FPM by nginx is present in Domains > example.com > PHP Settings, enable Proxy Mode in Domains > example.com > Apache and Nginx Settings
- Modify FTP account settings.
Set PHP-FPM handler back in Domains > example.com > PHP Settings
- If the issue still persists, temporarily suspend the subscription and try again.
