I have checked that the port 443 is closed and is not listed on my droplet.
Here is the output when i run the command :
root@ubuntu-1gb-blr1-01:/# netstat -ntlp | grep LISTEN tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 4749/mysqld 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:
sudo lsof -iTCP -sTCP:LISTEN -P
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.
Hello,
In addition to what has already been mentioned, not that you would need to have an SSL certificate installed in order for Apache to also listen on port 443.
You could use Let’s Encrypt to get a free SSL certificate and certbot will also do the Vhost configuration for you automatically:

Hello,
A solution is to use UFW in order to manage your iptables rules.
UFW, or Uncomplicated Firewall, is an interface to iptables that is geared towards simplifying the process of configuring a firewall. While iptables is a solid and flexible tool, it can be difficult for beginners to learn how to use it to properly configure a firewall. If you’re looking to get started securing your network, and you’re not sure which tool to use, UFW may be the right choice for you.
To enable UFW, use this command:
sudo ufw enable
You will receive a warning that says the command may disrupt existing SSH connections. We already set up a firewall rule that allows SSH connections, so it should be fine to continue. Respond to the prompt with y and hit ENTER.
The firewall is now active. Run the sudo ufw status verbose command to see the rules that are set. The rest of this tutorial covers how to use UFW in more detail, like allowing or denying different kinds of connections.
HTTPS on port 443, which is what encrypted web servers use, using
````sudo ufw allow httpsorsudo ufw allow 443```
You can also check our full tutorial on how to setup a firewall with UFW on Ubuntu: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-with-ufw-on-ubuntu-18-04
Hope that this helps! Regards, Alex
