How to enable Apache SSL Reverse Proxy on HTTP application - apache

Question

I've been having problems attempting to implement a reverse SSL proxy on Apache for an HTTP application on Ubuntu 14.04. As a baseline, the application works fine when I access it via port 8000 in the browser normally. For all intents and purposes, let's say the IP of my app is 192.141.56.11 (I do not have a domain name yet). The application runs with HTTP Basic Auth, I don't know if it's relevant. Basically I'm fishing for some glaring error here and would be grateful if you could help me out. Here is a log of my process:
I created my SSL cert and key and put them in the following locations:
/etc/apache/ssl/apache.crt (I performed chmod 644 here)
/etc/apache/ssl/apache.key (I performed chmod 400 here)
I then installed:
apt-get install apache2
a2enmod proxy
a2enmod ssl
a2enmod proxy_http
I then disabled the default config with:
a2dissite 000-default
I created the file "/etc/apache2/sites-available/redirect.conf"
I then created the file "/etc/apache2/sites-available/redirect.conf" and copied the text below:
<VirtualHost *:80>
Redirect "/" "https://192.141.56.11"
</VirtualHost>
After, I created the file "/etc/apache2/sites-available/reverse_proxy.conf" and copied below:
<VirtualHost *:443>
SSLEngine On
SSLCertificateFile /etc/apache/ssl/apache.crt
SSLCertificateKeyFile /etc/apache/ssl/apache.key
ProxyPass / http://127.0.0.1:8000/
ProxyPassReverse / http://127.0.0.1:8000/
and did:
service apache2 restart
I now attempt to access the UI of the application on another machine in the Chrome browser. When trying:
https://192.141.56.11
I get a general SSL connection error.
However, trying
http://192.141.56.11:8000
gives me the application, as if none of my config changed anything. However,
192.141.56.11:80
gives me an "Index Of" page with an html folder that says "Apache/2.4.7 (Ubuntu) Server at 192.141.56.11 Port 80"
192.141.56.11:443
gives me the same result except with "Apache/2.4.7 (Ubuntu) Server at 192.141.56.11 Port 443"
I've tried all manners of configurations but can't get what I want -- any ideas here?

Answer 1

EDIT: I tried https[:]//192.141.56.11 and got a more specific SSL error:
received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long)
EDIT2: After running apache, I get this warning;
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
I suppose this is fine as I am using an IP and not a domain name.
EDIT3: It turns out I needed to do:
a2ensite reverse_proxy.conf.
Now https[:]//192.141.56.11 works but defaults to an apache page. working on this.
EDIT4: I had to do
a2dissite default-ssl.conf
Now It actually redirects to the app on https[:]//192.141.56.11!! But I can still access the app via port 8000, which is bad {still working on}
EDIT5: IN the end, I couldn't figure out how to block access to the original app via port 8000 on Apache. Instead, I just implemented iptables on the server so that it can only be accessed via HTTPS. This is probably not the correct method. but all I could think of.
