I turned off the firewall. Then, using nmap in the terminal, I issued the statement
Starting Nmap 7.12 ( https://nmap.org ) at 2016-08-15 11:00 PHT Nmap scan report for localhost (127.0.0.1) Host is up (0.00016s latency). Not shown: 968 closed ports, 27 filtered ports PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 631/tcp open ipp 3306/tcp open mysql 9000/tcp open cslistener
How can I force open TCP 443 on my machine?
