Hi!

That log line above is where the Glance API server is using the glance
client to speak to the Glance Registry server, which runs on a separate
port from the API server (and possibly on a separate host entirely).

Make sure that in your /etc/glance/glance-api.conf file, you have your
registry_host and registry_port set appropriately. And in your
/etc/glance/glance-registry.conf, make sure you have your bind_interface
listening on the appropriate IP, which could indeed be 0.0.0.0.

Best,
