### Where is the URL used to view images defined?

I'm setting up an openstack cluster, and I think I must have made some mistake when installing glance, because when I run openstack image list, I get the following error: Unexpected exception for http://:9292/v2/images: Invalid URL u'http://:9292/v2/images': No host supplied. However, I can't seem to find where this faulty URL is stored, or how to fix it. Is it in a specific file? Thanks
