This message means one of these things: 1) The sshd process is not running, or is not listening on the default port. 2) A firewall is preventing your connection. You would normally check the first thing by using "ss" or "netstat" on the server, and verifying that the process is indeed LISTEN-ing on the expected interface(s) and port. For example: unicorn:~$ ss -ant | grep :22 LISTEN 0 128 0.0.0.0:22 0.0.0.0:* [...] This tells me that something is listning on port 22 on all IPv4 interfaces. If you don't see a line like this, then you need to investigate the ssh service more deeply. Perhaps start by running "journalctl -u ssh" to read its logs. If you *do* see a line like this, then you need to look at network-level stuff, like firewalls, routers, and so on.
