tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1626/sshd
tcp6 0 0 :::80 :::* LISTEN 17100/apache2
tcp6 0 0 :::22 :::* LISTEN 1626/sshd

Let’s list the services that are running:
Do you see Apache on port 443 on the list? If yes, then it might be a firewall issue. If no, then Apache isn’t listening on port 443, which probably is a wrongly configured VirtualHost, so let’s see the configuration for your sites.
Please let me know which Linux flavor, you are using.
In general you can use below command to open port 443 on any linux.
iptables -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT
service iptables save
service iptables restart
Hope it will help you.
Heya,
Just an update on an older question to clear some stuff up.
First, in order for your Droplet to listen on port 443, you need to configure something to use that port. In most cases, people configure Apache or Nginx, both are WebServices which allow your Droplet to server your website’s content.
With that said, even if you configure a WebService to listen on port 443 (which would be the secure port) you’ll need to allow it on your Firewall.
