Did you edit /etc/ssh/sshd_config?
Is OpenSSH running?
sudo ps wwaux | grep ssh
I think no:
I trying:
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?
I did not open this directory never. I connect only as root
Is there a firewall running? What's the output of
sudo iptables -L -n -v

Add server ip address to /etc/hosts

vi /etc/ssh/sshd_config

PermitRootLogin yes
PasswordAuthentication yes
AllowUsers user_a user_b user_c
systemctl reload sshd
