Cannot open port 443

Dear All,

       We are having a CentOS 7.4 on which the CWP is installed. Almost 60 domains are running on the server. We are planning to install SSL certificate for one of the domain. So we are trying to open the port 443 but we are not able to do so,

[root@srv ~]# telnet localhost 443
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

[root@srv ~]# systemctl status firewalld
● firewalld.service
   Loaded: masked (/dev/null; bad)
   Active: inactive (dead)

[root@srv ~]# service iptables status
Redirecting to /bin/systemctl status iptables.service
Unit iptables.service could not be found.


Thank You,

           

Looks like you have no service (Apache) that listen on port 443

exec this command in shell

netstat -an|grep 443
