Too many redirects error with https and domain access module
Just in case anyone stumbles upon this (or perhaps for my future self). The issue ultimately ended up being Cloudflare. If you use Cloudflare for any of your domains don't forget to include it in the stack of things you're looking at when debugging (like I did).

If you use Cloudflare, there is a section under the "Crypto" menu for "SSL". I believe the default setting is "Flexible", if you leave this setting you can end up in a situation where you're bouncing between your load balancer and Cloudflare.
The setting you want is "Full" once it is set to "Full" you shouldn't keep getting bounced around.

This also explains why our .com was not getting the redirect error. Our .com is the only domain not on Cloudflare b/c that DNS is out of my control
