I am currently unable to create or delete instances in my OpenStack Cloud (the cloud was working properly before, for a long time) .
Everything seams to be working properly acording to [juju status](https://pastebin.ubuntu.com/p/q8PGBGbDWB/), but I am unable to create instances, they get stuck in Building status and when I try t delete an instance I got the following error.
mchc@ubuntu:/data/git/openstack-cfg/client$ openstack server delete --wait 45f3f3ff-8f72-4953-8894-3eab2c3affe8
