To get this to work:

you need to have https/port 443 configured correctly and open
(including through firewalls) to whatever networks you want to give
it access from (localhost, internal, external).

Your telnet test shows you successfully connecting -- via ipv6
(Trying ::1...) -- to port 443 on the local machine. You need to
continue testing the "b" and "c" options from my earlier message:

  > (ideally external) network

if you want clients to be able to connect from "b" internal networks
and/or "c" external networks.

As noted earlier, your netstat output is only showing ipv6 for port
443. That may be what you want, but generally isn't sufficient for
full external client access. If you need ipv4 too you'll need to
configure things appropriately -- that's a host networking, not
apache/httpd, issue.

By the way, the "s_client" test that was suggested is useful, but I
think is harder to get the different types of server side responses
from than a simple telnet. If the port is open but it's potentially a
security protocol/certificate issue, then s_client is the right tool.
Trying to debug your current issue with a browser is almost useless.
