I am having strange problem. My ispconfig 3 runs on ubuntu 10.04 . Its almost 6 months i am running this server and working good. Few days ago i upgrade packages of ubuntu . Now Ftp client like filezilla cannot establish to the server. It display Connection timeout. But when i try to connect ftp connection from my laptop to webserver with terminal , it gets established. I can see all folders of remote host (webserver). I look after log and cannot see any log. In log it show you are log in. Help urgently needed.
