Hosts file aanpassen
De FQDN voor op, daarna pas de aliassen
/etc/hosts
<IP_SERVER> ()
Mocht er een alias voor de FQDN staan, dan kun je foutmeldingen krijgen die hier niet meteen aan te relateren zijn.
Als je gebruikt maakt van een hosts file, let dan goed op dat er FQDN's in staan en de volgorde waarin.
Controleer de hosts file en pas deze eventueel aan:
De FQDN voorop, daarna pas de aliassen.
