I have an amazon EC2 amzn-ami-hvm-2014.09.2.x86_64-ebs instance running and port 443 does not seem to be open, even though I have added it to the instance's security group, both inbound and outbound settings:

enter image description here

I have run netstat on the EC2 instance and port 443 is not listed:

$ sudo netstat -nupt -l 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 2595/java tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 2061/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2103/sendmail tcp 0 0 127.0.0.1:8005 0.0.0.0:* LISTEN 2595/java tcp 0 0 0.0.0.0:8009 0.0.0.0:* LISTEN 2595/java tcp 0 0 :::22 :::* LISTEN 2061/sshd udp 0 0 0.0.0.0:68 0.0.0.0:* 1868/dhclient udp 0 0 172.31.40.1:123 0.0.0.0:* 2080/ntpd udp 0 0 127.0.0.1:123 0.0.0.0:* 2080/ntpd udp 0 0 0.0.0.0:123 0.0.0.0:* 2080/ntpd

How can I open the port 443? port 80 is working fine.

EDIT: more info added

I'm running a web app on tomcat 8. When entering the ip address on the internet browser, it is successfully redirecting to https. But the page does not display.

On my apache8/conf/server.xml file I have:

<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="443" />

and 

 <!-- Define an AJP 1.3 Connector on port 8009 --> <Connector port="8009" protocol="AJP/1.3" redirectPort="443" />

It works fine on my development machine, successfully redirecting to port 443.

Thanks in advance, Lucas

Reset to default

You need to configure apache(if you are running apache or the webserver you are using) to start using port 443. If you are using ubuntu you need to execute the following

sudo a2enmod ssl sudo a2ensite default-ssl sudo /etc/init.d/apache2 restart

Thanks, Dimos. I'm running a web app on tomcat 8. When entering the ip address on the internet browser, it is successfully redirecting to https. But the page does not display. It works fine on my development machine, successfully redirecting to port 443.
I also went through the process of opening the ports 80 and 443 as described on this page: java-notes.com
Glad I could help. Sometimes we just miss even the things we did so many times before

Thank you, Dimos Karagiannis for your answer.

I am working with tomcat8 and I totally forgot to set up Tomcat SSL configuration as stated on Tomcat's well documented page.

It was one of those things that I tried everything, except for the one thing I had done numerous times in the past.

To test that SSL was working, I quickly generated a keystore file (linux):

sslKeys]$ sudo keytool -keysize 2048 -genkey -alias tomcat -keyalg RSA -keystore tomcat.keystore Enter keystore password:changeit Re-enter new password:changeit

After having generated the keystore, I just referenced it from tomcat8/conf/server.xml file:

<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" teystoreFile="/pathTosslKeys/tomcat.keystore" password="changeit" />

That worked. This is only a temporary thing. I need to add a properly generated ssl cert.

I am a numpty!

you needed a ssl cert, but you also needed to have the connector port 443 line, yeah? It appears that was missing.
