[ovirt-devel] CI failures due to oVirt proxy getting forbidden access to CentOS mirrors

Hi, we are experiencing build failures due to *08:49:10* # /usr/bin/yum --installroot /var/lib/mock/epel-8-x86_64-6c17b26f3795335ce1ac45b0dcdbc9d5-bootstrap-8304/root/ --releasever 8 install dnf dnf-plugins-core distribution-gpg-keys --setopt=tsflags=nocontexts <https://jenkins.ovirt.org/job/ovirt-appliance_master_build-artifacts-el8-...
