drweb problem after update

[onweb]

Hello,
after upgrading to 8.1 (debian 3.1) drweb stopped working.
Error message:
Error reading from socket (Connection reset by peer)!
The licence key is ok, when I stop drweb, the .deamon file and the pid-file are deleted. netstat shows no other program using the socket.
From the logfile: "Daemon is installed, active interfaces: /var/drweb/run/.daemon 127.0.0.1:3000"

Are there any ideas?

Thank you
