Public port 80 targeting private port 3000 on Azure Linux

Question

I have a Ruby on Rails website on Azure Linux (Ubuntu 14.04) that works perfectly from this address:

http://mydomain.cloudapp.net:3000

I want to get rid of the port in the address, and redirect it to a subdomain I have. I have set up the 000-default.conf on Apache as per below:

<VirtualHost *:80>
    ServerName myweb.example.com
    DocumentRoot /var/www/html/mywebsite
    ProxyPass / http://localhost:3000/
    ProxyPassReverse / http://localhost:3000/
</VirtualHost>

I have restarted apache2. On my domain manager I have created a CNAME from myweb.example.com to mydomain.cloudapp.net.

However, when I enter http://myweb.example.com I get 500 internal server error. It does work with http://myweb.example.com:3000. What am I doing wrong?

EDIT: error_log info after trying to access http://myweb.example.com

 If you are using a DSO version of mod_proxy, make sure the proxy submodules are
 included in the configuration using LoadModule.

Looks like you just need to load mod_proxy_http.

That's it. sudo a2enmod proxy_http fixed my issue – Arturo Aug 23 '15 at 16:08
