Can not get admin working on dedicated domain and dedicated admin server

Can not get admin working on dedicated domain and dedicated admin server

Hi,

 

I've been struggling with this for a number of days. I have a staging/dev site setup on AWS with the following architecture:

Main Store Site

 

(HTTPS/HTTP)AWS ELB -------> Varnish (dedicated server) -----> NGINX (dedicated server) -----> PHPFPM (dedicated server). 

Admin site

(HTTPS/HTTP)AWS ELB -------> Varnish (dedicated server) -----> NGINX (dedicated server) -----> PHPFPM (dedicated server). 

 

I have SSL offload working for the site using the HTTPS=on fastcgi_param and setting the Offloader header to X-Forwarded-Proto and the admin is accessible by going to the  main store site like so https://dev.example.com/admin_dev.

 

However we are trying to split the admin so it would work from admin-dev.example.com/admin_dev. This url resolves to a dedicated set of admin servers which have an identical code base to the store site.  We have tried setting the following:

 

Screen Shot 2017-03-24 at 13.41.55.pngWe thought this would work however we end up in an infinite redirect loop where it seems to be redirecting to itself. We aren't really sure what to change at the moment. 

 

We are using the following nginx configuration:

 

map $http_x_forwarded_proto $fastcgi_https {
    default $https;
    https on;
}
server {
    listen 80;
