FTP Login suddenly does not work anymore

[Floezen]

I have a freshly installed Plesk 12 on CentOS 7.
FTP logins worked fine yesterday. Today I get a 530 Login incorrect.
I think the only change since yesterday was a server reboot.

/var/log/secure tells me that /etc/ftpusers is missing

Jun  8 00:33:19 macbook proftpd: PAM unable to dlopen(/usr/lib64/security/pam_stack.so): /usr/lib64/security/pam_stack.so: cannot open shared object file: No such file or directory
Jun  8 00:33:19 macbook proftpd: PAM adding faulty module: /usr/lib64/security/pam_stack.so
Jun  8 00:33:19 macbook proftpd: pam_listfile(proftpd:auth): Couldn't open /etc/ftpusers

What went wrong, what would be the solution?

Look at this solution http://syamkumar-linux.blogspot.ru/2013/04/how-to-fix-proftpd-login-failed-error.html or http://www.raymondpopowich.com/sys-admin/plesk-proftpd-pam_stack-so-file-directory/

1. How do I restart the Plesk ProFTP?

systemctl restart proftpd

->
Failed to issue method call: Unit proftpd.service failed to load: No such file or directory.

/etc/init.d/xinetd restart

->
-bash: /etc/init.d/xinetd: Datei oder Verzeichnis nicht gefunden

2. Restarted the whole server instead. But changes as mentioned in above link did not help.

less /var/log/secure:

Jun  8 14:14:46 illenberger proftpd: pam_listfile(proftpd:auth): Couldn't open /etc/ftpusers

Looks like the same issue https://talk.plesk.com/threads/ftp-login-error-530-after-install.325909/

I had the same problem and I figure out that the hostname was wrong. Check it out
