    Verbose mode:
    Code:

    Looks like a firewall issue. What's the output of
    Code:
    iptables -L
    ?

    Have you tried to disable the firewall for testing purposes?

    Are there any firewalls between you and the server (routers, etc.)?

    Yes we have MikroTik router.
    But all work with this router configurations until server was rebooted.

    Is it possible you ran iptables rules on the command line (without putting them in some configuration file)? Those iptables rules are lost on reboot.

    Thank you Falko.

    No there are no iptables that runs via command line.

    We restart server at other time when active mode worked, and after restart it was ok.

    I think it was some updates, and after restart active mode goes down.
    it was dh-apparmor, but I delete it after that by apt-get remove.

    Any ideas?
