Hi Team Nova develop! I build OpenStack version Queens with 05 node (03 node controller, 02 node compute). I use HAproxy to load balancer all services. First, I create endpoint with http protocol. Everything is successful. Next, I change endpoint from http to https. After complete, I use openstack command normally. But, I can not use nova command, endpoint nova have been redirected from https to http.
