Public bug reported:

Dalmatian 2024.2

Using auth_url in service_user section in nova.conf (for both control
and compute nodes) from official docs will lead to critical errors while
launching an instance:

The workaround for this is to define port and http protocol for keystone
authentication:

Instead of "auth_url = https://controller/identity"; should be used:

auth_url = http://controller:5000/identity
