When I tried to log into my remote Ubuntu server today, I got:

ssh: connect to host <ip> port 22: Connection refused

So I rebooted the server, thinking sshd might have crashed.

After the boot I could connect via ssh, but after 1 or 2 minutes the server closed the connection:

Connection to <ip> closed by remote host.

Trying to reconnect, the server refuses the connection again.

Manually doing

/etc/init.d/sshd restart

didn't help, /etc/hosts.deny seems ok.

This is extremely annoying, since I have so little time to diagnose or fix the problem. Help or ideas are greatly appreciated!

When the error message is "Connection refused" it means that sshd is no longer listening on your ssh port. If it was your firewall, you would have received a "Timeout". In either case, do ssh with verbose option and see exactly at what step the connection is getting dropped.
