Comment 5 for bug 1967945

I was trying to create the reproducer but
```
[root@b9d412d93405 /]# python3 -m venv ovb_repro
[root@b9d412d93405 /]# source ovb_repro/bin/activate
(ovb_repro) [root@b9d412d93405 /]# pip install python-openstackclient python-heatclient python-novaclient python-neutronclient python-glanceclient -c https://raw.githubusercontent.com/openstack/requirements/stable/wallaby/upper-constraints.txt -i http://mirror.regionone.vexxhost-nodepool-tripleo.rdoproject.org/pypi/simple, http://mirror.regionone.vexxhost-nodepool-tripleo.rdoproject.org/wheel/centos-9-x86_64 --trusted-host mirror.regionone.vexxhost-nodepool-tripleo.rdoproject.org

```

But http://mirror.regionone.vexxhost-nodepool-tripleo.rdoproject.org/wheel/centos-9-x86_64 is giving 404. Can we get this mirror back?
