Can't clone via HTTPS for CI Runners

Hi Folks,

Here's my goal: Run CI Multi Runner on a Mac for an iOS/Android project.

Here's what I'm running:

1. CentOS 6 Server with: Omnibus Gitlab v. 8.9.6-ce (Separate NGINX setup, v1.6.2 ) (also, note, this is a recent upgrade from Omnibus V7?)
2. Mac OS El Capitan (10.11?) with Xcode and everything. (Manually clones just fine via ssh)

Here's my NGINX setup for gitlab on the Centos Server:

upstream gitlab {
  server unix:/var/opt/gitlab/gitlab-workhorse/socket;
}

server {
  listen 80;
  server_name mygitinstall.com;
  return         301 https://$server_name$request_uri;
}

server {
  listen 443 ssl;
  server_name mygitinstall.com;
  server_tokens off; ## Don't show the nginx version number, a security best practice
  root /opt/gitlab/embedded/service/gitlab-rails/public;

  ssl on;
  include ssl.conf;
  
  ssl_ciphers "ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4";

}

Here's what i've run into:

1. Clone works fine from SSH, but not HTTPS
2. HTTPS clone works for tiny repos, but anything bigger and it fails pretty much right away with the below message:
3. I've ran the clones using the CI tokens too and it fails for big repos (over 50mb-ish), but not the little repos (5mb-ish).

git clone https://gitlab-ci-token:[token]@mygitinstall.com/person/project.git
Cloning into 'project'...
remote: Counting objects: 7626, done.
error: RPC failed; result=18, HTTP code = 200   
remote: Compressing objects: 100% (6382/6382), done.
fatal: The remote end hung up unexpectedly
fatal: early EOFs:   0% (1/7626)   
fatal: index-pack failed

I'm sure you've seen this before. I've looked through your issues list and found similar things. So, I upped the Unicorn.rb settings timeout to 6000 seconds (configured via gitlab.rb presented below) Workhorse has its timeout set to 10 minutes too.

Also, since its 8.9 series, Here's how things are running: my NGINX <---> Workhorse <---> Unicorn

Let me know what I'm doing wrong and how I can fix this. Attached is my full gitlab.rb file for reference. gitlab.rb

Please let me know what I should do to fix this problem.
