OK it's fixed!
On intoDNS, I can see this for "yugiohjcj.tk":
Code:
Domain NS records Nameserver records returned by the parent servers are:
ns1.yugiohjcj.tk. ['82.65.164.110'] [TTL=300]
ns2.yugiohjcj.tk. ['82.65.164.110'] [TTL=300]
a.ns.tk was kind enough to give us that information.
In fact, it was a problem on Freenom.
The domain was not correctly configured.
I had to do the following:
1) Services, My Domains, Manage Domain, Management Tools, Register glue records:
ns1.yugiohjcj.tk 82.65.164.110
ns2.yugiohjcj.tk 82.65.164.110
2) Services, My Domains, Manage Domain, Management Tools, Nameservers:
[X] Use custom nameservers (enter below)
Nameserver1: ns1.yugiohjcj.tk
Nameserver2: ns2.yugiohjcj.tk
If you don't do that, exactly in this order, there is an error and the domain is not correctly configured.
