Open Stack

Are you using a tls proxy in front of Nova API? if so, you need to
adjust the osapi compute_link_prefix -
https://docs.openstack.org/ocata/config-reference/compute/api.html to be
the https url, otherwise it will autodetect as http. The ec2-service (or
novaclient) is probably doing link following from returned links, and
thus fails hitting the http ones.
