Verify /etc/host entry for Minikube

This entry:

127.0.0.1 gracedb gracedb.default.svc.cluster.local

does not work in my Minikube installation on Alma9. I have to use:

10.100.100.10 gracedb gracedb.default.svc.cluster.local

Possibly it's different between Macos and Linux, or it's due to the new Traefik version I have installed? Needs to be understood.
