Comment 19 for bug 1952414

This FQDN vs hostname may not be the root source of the issue. I did see the tendency multiple times in a row but there were some cases where one of some services failed even without having the difference on FQDN vs hostname.

In the following case, cinder failed to create a symlink of a cert while glance worked. But I don't see much difference in the relation data.

Anyway, hope I offered enough data by now to reproduce the issue so someone familiar with the logic of this HTTPS setup code can take a look.
