    i had the same problem but if you are runing UFW you have just to stop it or allow ssh access.
    you just have to login in your droplet and use ssh access to desable the firewale or to allow _ssh acess.

Try running these commands and then start ssh (service ssh start): 
rm /etc/ssh/ssh_host_*

/usr/sbin/dpkg-reconfigure openssh-server

No. Today I had rebuild my droplet (Ubuntu 12.04 x32)- installed LAMP, created user, edited apache config. Few hours ago I opened and connected to droplet using putty and tried connect to droplet via SFTP (FileZilla). FilleZillla say "Network error: Connection refused" and I closed and open putty and he also say "Network error: Connection refused".

Hmm. I believe openssh logs to syslog, check if there are any errors: 
sudo tail -30 /var/log/syslog

sudo tail -30 /var/log/auth.log

So you have not edited anything in /etc/ssh/sshd_config? What do you have listed in the AllowUsers directive? Is the username listed, that you're attempting to log in with?

Is there a firewall running? What's the output of 
sudo iptables -L -n -v
?
