use

netstat -na

to check if somethng is LISTENING on port 443 then shutdown that service or change its port

you should also check if there is any firewall rules on that port

iptables-save

hope it helps.

OK, i try 80 port and it’s working, this is useful

thanks for answer but i use only ssh server, no web server.

Are you running a web server with SSL? If so, then your web service would already be using port 443 and you should select a different one. You should be able to access your droplet to do this via the web console in the control panel.

Hello,

In addition to what has been mentioned, I advise against using a reserved port for SSH, 443 is a reserved TCP port for HTTPS:
