I also noted that, but don't know what to do. >As you seem to receive some resources via HTTP, the request should get >logged somewhere. I use "tail -f /var/log/apache2/access.log" and error.log on the console and then enter IP address in the browser.When I enter http://w.x.y.z the page is shown and access.log shows some messages.I also see some debug messages in error.log IMO, the messages aren't important! since I see the page in the browser.However, when I enter https://w.x.y.z nothing is shown in the console. >You always tell you're accessing "w.x.y.z" and >said "the server's page is reachble by an IP address", so I understand >you're not using a host name, but IP address to connect. w.x.y.z reads >like an IPv4 address, while your earlier report of open ports just >gave an IPv6 port open for listening: > >root@webshub:~# netstat -tulpn | grep 443 >tcp6 0 0 :::443 :::* >LISTEN 14709/apache2 > >So there might be a chance your browser's requests doesn't even end up >in *your* server. I also think such thing is the root of the issue. Things are 1) Yes, I don't have hostname. So, I have to enter ip address. 2) The SSL certificates are created for our university where they have host name. 3) I don't know if the certificates are only usable with subdomains only. Any thought? 4) The netstat command shows the IPv6. Is that a firewall issue? iptables? ufw?
