[Proftpd-user] Hi

Hello,
I am nut sure if I am in the right list. I used proftpd for about 2
years on a debian server. Recently I niticed that I can´t connect anymore.
Filezilla states:
"Status: Nächsten Versuch abwarten...
Status: Verzögere Verbindungsversuch da der vorherige fehlgeschlagen ist...
Status: Verbinde mit 192.168.1.252:21...
Status: Verbindung hergestellt, warte auf Willkommensnachricht...
Fehler: Zeitüberschreitung der Verbindung
Fehler: Herstellen der Verbindung zum Server fehlgeschlagen"
and so on and so on.
proftpd.log in va/log states only open and close of a connection
"Jun 06 21:08:48 LS-GL7D6 proftpd[1456] 127.0.0.1
(Workstation[192.168.1.100]): FTP session opened.

Jun 06 21:09:13 LS-GL7D6 proftpd[1470] 127.0.0.1
(Workstation[192.168.1.100]): FTP session closed."
Syslog states only connection:
"Jun 6 20:57:27 localhost proftpd[1216]: connect from 192.168.1.100

Jun 6 21:08:00 localhost proftpd[1470]: connect from 192.168.1.100
(192.168.1.100)"
And I don´t know anymore what the problem could be.
Does anybody have an idea how to solve the problem? I (think - ... hope
...) that I didn´t change anything on my server. I tried apt-get remove
and install ... "played" with configs .. but I can´t see any error
message pointing at the problem.
This is how my proftpd.conf looks like:
