Configuration: Debian 7.0 64bit, ProFTPD 1.3.5, no firewall

Ftp client stops on entering passive mode (Total Commander).
This situation is not in 100% tries (50% i think).

In log i have no errors.

This problem affects all clients and software (aptana, total commander, filezilla).

Yesterday all works OK, but today i have problems. I changed nothing in the system.

Maybe somhe know how to solve this problem. I don't know how to diagnose them :(.
Is it possible that the problem is the network of a dedicated server provider

Regards
 
Hello,

You probably need to modify your /etc/proftpd.conf and uncomment line with:

Code: 
ExtendedLog    /var/log/proftpd/paranoid.log ALL default

and then restart proftpd. Wait for a while untill the issue happens again and check the log.
 
Nothing useful in log:
