Gzip failing messages on nginx proxy environment

Problem:

Gzip is failing for js files and Gzip is failing for css files messages on status report

Environment:

--- HTTPS ---> Nginx Proxy (caching and ssl termination) --- HTTP ---> Nginx Web Server (where drupal lives)

Enabled Modules/Versions:

Drupal 7.39
AdvAgg 7.x-2.15+10-dev
HTTPRL 7.x-1.14+32-dev + patch (Allow to define a port - and some cleanup.)
cURL HTTP Request 7.x-1.7+1-dev

Tests:

• Upgraded to nginx to 1.8.1
• Upgrading php to version 5.6
• Quadruple checked nginx configurations
• Verified Gzip is working

Steps to gzip issue:

• Based on the issue Advagg hook_requirements() don't work if self-site not directly accessible, I have added "127.0.0.1 www.example.com" to my /etc/host file, and still get Adv CSS/JS Agg - Self Request Failure HTTP loopback requests to this server are returning a non positive response code of -1004(screenshot here) still shows on my report.
• After I manually verified that AdvAgg is working correctly like report message suggests, I set $conf['advagg_skip_404_check'] = TRUE; in settings.php
• After refreshing report page, I receive the gzip errors below. I believe it is very similar to the issueAdvAgg returning ssl error (maybe httprl related); however, the solution didn't seem very legitimate (SSL key doesn't seem like my issue here).

Solutions?

I have been facing this issue for months. Everything is working correctly I believe, but the messages still appear that gzip isn't working. I understand a proxy in front of the web server isn't the "standard" setup people use, but I can't believe more people aren't discussing this issue in the queue. Obviously a few people have had problems, but I just can't find what the ultimate solution is.

Gzip Errors:

<?php
Adv CSS/JS Agg - gzip	Gzip is failing for js files.
The web servers configuration will need to be adjusted. In most cases make sure that the webroots .htaccess file still contains this section "Rules to correctly serve gzip compressed CSS and JS files". Certain default web server configurations (nginx) do not gzip HTTP/1.0 requests. If you are using cloudfront you will have to add metadata to the .gz files. There are some other options if using cloudfront. Raw request info:
