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.
Problem solved !
VirtualHost was wrongly configured. Now the port 443 is listing using this command :
: 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 4269/apache2
tcp6 0 0 :::22 :::* LISTEN 1626/sshd
tcp6 0 0 :::443 :::* LISTEN 4269/apache2
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.
When i run command service iptables save then Error "iptables: unrecognized service"
