Apache2 SSL does not work on server or AWS

1. Check if apache2 listens 443

netstat -ntupl | grep :443

https://bobcares.com/blog/apache-not-listening-on-port-443/

2. Check if apache2 port conf

Apache2 either put listen 80 on virtual host config file /etc/apache2/sites-available/000-default.conf and listen 443 on virtual host config file /etc/apache2/sites-available/default-ssl.conf 

or at /etc/apache2/ports.conf

If not add listen 443

the listen 443 statement is usually wrapped around in <if statement

<IfModule  ssl_module>

listen 443>

</IfModule>

3. Check if ssl_module installed

dpkg -S mod_ssl.so

Should show something like :

apache2.2-common: /usr/lib/apache2/modules/mod_ssl.so

then enable the module a2enmod ssl

then restart sudo service restart apache2

if not install :

install the ssl_module by:(99% time the ssl_modl comes with apache2 server)

apt-get install mod_ssl

Also check on AWS networksecurity group to ensure port 80 and 443 are enabled for incoming traffic:
