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

Please let me know how can I open 443 port So that my website works over https.

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.
