Multiple issues with NGINX and Multisite

I recently transferred a client's private site to an nginx server to speed things up. I've had great success using Nginx in the past though this is the first multisite I've moved.

I'm getting two issues a the moment.

1: If I try to go to one of the Admins for a sub-site I get the error: This webpage has a redirect loop

2:If I go to one of my sub sites all of the images are missing and I see the url for the image are Mainurl.com/subsite/imagepath.jpeg.

I've tried changing permalinks along with many other options but no luck.

Any suggestions would be great.
