I have checked the issue and it seems that two out of the three nameservers from digitalplat.org are currently not working. Only ns1.digitalplat.org seems to be working, but ns2.digitalplat.org and ns3.digitalplat.org do not appear to respond to any queries.
Our ability to show and verify DNS information relies on the DNS of your domain actually working correctly, which doesn’t seem to be the case.
If this issue persist, please consider checking with DigitalPlat what the status is regarding this system degradation on their end.
And in case it wasn’t clear: this is not an issue on our end.
Please note that the DNS information shown in the client area is based on the actual DNS information of your domain. We do not use WHOIS information for this purpose (for a variety of reasons).
