Unable to connect to stream repo on Rocky Linux since the change from mirrorlist to baseurl

[mikep234]

Following the instructions from here I am trying to rebuild a self hosted engine.
https://ovirt.org/download/install_on_rhel.html

I am using Rocky linux 8.9
[root@kvmnode1 yum.repos.d]# vim Centos-stream-extras.repo
[root@kvmnode1 yum.repos.d]# vim Centos-stream-extras-common.repo
[root@kvmnode1 yum.repos.d]# dnf repolist
repo id repo name
appstream Rocky Linux 8 - AppStream
baseos Rocky Linux 8 - BaseOS
cs8-extras CentOS Stream 8 - Extras
cs8-extras-common CentOS Stream 8 - Extras common packages
[root@kvmnode1 yum.repos.d]# echo "8-stream" > /etc/yum/vars/stream

[root@kvmnode1:]# dnf distro-sync --nobest
CentOS Stream 8 - Extras 16 kB/s | 7.9 kB 00:00
Errors during downloading metadata for repository 'cs8-extras':

• Status code: 404 for https://vault.centos.org/pub/rocky/8-stream/extras/x86_64/os/repodata/repomd.xml (IP: 18.165.83.66)
  Error: Failed to download metadata for repo 'cs8-extras': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried.

Back months ago this worked with the mirrorlists because I was able to build a self hosted engine. What changed?

@slmingol any ideas here?
