Public bug reported:

Hello everyone,

I installed openstack queens in centos 7.5.

I tried to create an instance with using dashboard and CLI and both got
error messages below:

Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
<class 'neutronclient.common.exceptions.Unauthorized'> (HTTP 500)

nova-api.log shows the following:
