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.

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? Here is the output of ufw
root@webshub:~# ufw status
