I try to enable HTTPS, I have a valid certificate installed, and it works fine when I connect to the server within our company.
But from outside our company (e.g. sitting in my customers office) I can't get a connection over https (while http is working fine).
Using Internet Explorer, I get 'Internet Explorer cannot display the webpage', clicking 'Diagnose Connection problems' will give 'Windows received an HTTP error message: 403 (forbidden)'
It could be some firewall problem, but HTTPS in general is not blocked.I think the question was more related to incoming HTTPS connections (port 443 TCP) on the network you've deployed your APEX Listener at. Does your host have a public IP adress at all or is there a NAT rule that forwards incoming connections to your host?
E.g I can access Gmail, and also this very forums.oracle.com is https which I can access from my customers office.

Thanks for the reply.
There is NAT from the internet to an internal IP adress to my host.
Is there something special I should set for port 443?
My apex login is not using port 443 directly, the address is like
The strange thing is, that in some places I can connect to our site, but not from everywhere.

I can try the port which is used as standard by Glassfish (8181), I can try 443 as well but I doubt if I can open that port.
Even if I can open it, isn't is more vulnerable for hackers then?
