can't ssh remotely, ssh port is closed from outside
I was able to ssh in remotely to my droplet yesterday. I didn't change anything but I can't do it today.
I use the standard WordPress on Ubuntu 14.04 droplet.
I can ssh locally back to the server using the droplet console.
I've tested from other IP (using http://www.infobyip.com/sshservertest.php ) and it doesn't work either.
Web server on port 80 works.
The firewall seems to be empty:
ipchains -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination
I also checked /var/log/kern.log when I tried to connect, nothing.
I tried to restart the droplet, didn't help.
I'm kind of lost what else should I try
Is there a firewall front of my droplet which might block my ssh?
Is there any other diagnostic you could recommend to locate the issue?
I would appreciate any help.
