Apache SSL not accepting outside traffic

Question

Running Apache 2 on Ubuntu 11 in Amazon EC2. Tried to add a new SSL VirtualHost by doing the following:

Added "Listen 443" to ports.conf. Added new VirtualHost in my enabled site and "SSLEngine on".

The strange thing is this: I can curl https://localhost and get a response, but I can't curl my https url from a remote server.

Netstat shows that it's listening on 443:

# netstat -tulpn                         
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      1923/apache2    
tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      1923/apache2    
tcp6       0      0 :::22                   :::*                    LISTEN      482/sshd        

But, if I nmap the internal IP from another collocated EC2 box, it shows that only ports 22 and 80 are open:

$ nmap -P0 xx.xxx.xx.xx  

Starting Nmap 5.21 ( http://nmap.org ) at 2013-02-23 09:48 UTC
Nmap scan report for xxx
Host is up (0.00058s latency).
Not shown: 998 filtered ports
PORT   STATE SERVICE
22/tcp open  ssh
80/tcp open  http

Nmap done: 1 IP address (1 host up) scanned in 3.98 seconds

Additionally, I have verified that ufw is disabled and there are no entries in iptables.

Can anyone offer suggestions on how to troubleshoot this? Thanks in advance!

Answer 1

Does your AWS Security Group for your EC2 instance allow inbound 443? It needs to for HTTPS Traffic to work.

That sounds like it might be your problem to me!
