> All other commands so far has worked fine. I can see services in nova and upload images in glance

Specifically, which glance commands worked?

Does a 'glance image-list' work?
Does a 'glance image-show <id>' work?

It looks like the glance registry can't validate tokens:

2016-02-05 17:52:58.133 1845 CRITICAL keystonemiddleware.auth_token [-] Unable to validate token: Unable to establish connection to http://controller-win:5000/v2.0/auth/tokens
2016-02-05 17:52:58.190 1845 INFO eventlet.wsgi.server [-] 127.0.0.1 - - [05/Feb/2016 17:52:58] "GET /images/detail?is_public=none&limit=20 HTTP/1.1" 503 235 4.373681

If you send a curl command directly to the registry to list images what happens?

$ curl -v -H 'x-auth-token: <insert-a-real-token>' http://<registry-ip>/images/detail?is_public=none&limit=20'

what do the relevant glance-api.conf and glance-registry.conf configuration sections look like?
