builds fail even with faster runner

first example :

https://gitlab.adullact.net/adullact/puppet-freeipa/-/jobs/4985

On ipa-server2 the command yum is unable to install sssd with message :

Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install sssd-common' returned 1: One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail.

second example :

https://gitlab.adullact.net/adullact/puppet-freeipa/-/jobs/5007

On ipa-server2 the following command ipa-replica-install failed.

The command :

/usr/sbin/ipa-replica-install --principal=admin --admin-password='vagrant123' --hostname=ipa-server-2.vagrant.example.lan --realm=VAGRANT.EXAMPLE.LAN --domain=vagrant.example.lan --server=ipa-server-1.vagrant.example.lan --setup-dns --no-forwarders --ip-address 192.168.44.36 --no-ui-redirect --unattended

The error message :

ERROR : Reverse DNS resolution of address 192.168.44.36 (ipa-server-2.vagrant.example.lan) failed. Clients may not function properly. Please check your DNS setup. (Note that this check queries IPA DNS directly and ignores /etc/hosts.)

Needs to be investigated.
