How do I solve Name server glue missing issue from WHM?
The A records (the GLUE) got from the parent zone check are the same as the ones got from your name servers. You have to make sure your parent server has the same NS records for your zone as you do according to the RFC. This tests only name servers that are common at the parent and at your name servers. If there are any missing or stealth name servers you will be getting warning and will create issues or delay in response.
Error will be, “None of your local name servers can be authoritatively resolved, and no glue is proved. This will cause intermittent resolutions failures when the cached local NS record are used to resolve your domain.”
To solve the same you have to follow the below procedure,
If you are using private name server it should have zone record for NS1 and NS2.
2.Under DNS Functions choose Edit DNS Zone option
Confirm whether NS1 is having zone for NS1, NS2, A record, MX record and CNAME for mail, FTP and www too as ns1.example.com same for ns2.example.com
3.Click on Save.
Once the changes done you will get the issue solved.
