Missing nameservers reported by parent FAIL: The following nameservers are listed at your nameservers as nameservers for your domain, but are not listed at the parent nameservers. You need to make sure that these nameservers are working.If they are not working ok, you may have problems!
This usually occurs when there is a mismatch between the name servers that you’ve assigned at the registrar end and the ones in your DNS zone file. Also, check the IPs and correct any mismatches. That should fix the issue.
