Ok I registered a .ca domain this week and have been trying to set the custom nameservers but when I click submit the changes do not stay and goes back to the godaddy defauly why???
Does a record of your domain exist on the nameservers you are changing to? What happens when you run the following on terminal?
# dig domain.tld @ns.nameservers.tld
"domain.tld" being your domain and "ns.nameserves.tld" the new nameserver.
