I have 3 domains with extension .it, .de and .nl where I can’t update the nameserver. My registrar told me that there is an error in the actual settings of the domain DNS and told me to check with zonecheck.org
When I do so I can see that my domain has a fatal error :
-does not support EDNS
Without correcting that I can’t modify my nameserver.
Can anyone help on that ?
Thanks in advance
