Issue DNS issue on four domains

[jorge ceballos]

Server operating system version

centos 7

Plesk version and microupdate number

Plesk Obsidian 18.0.52 update 3

Hi,

4 domains in the server show "dns not resolvable" though they are configured exactly like the rest which are working ok.
Compared the domains' zones in var/named/chroot/var and they are exactly the same - working and non-working.
When running dig for these 4 domains, A record is not shown at all; the rest are ok.
Reapplied dns layout to no avail.

Any idea?

TIA

Is your server entered as the authoritative nameserver in the domain datasets where you lease your domains?

Hi Peter,

Yes, all the domains -working and non working - point directly to our Name Servers.

Some minutes ago, ran a check at dnschecker.org and the failling domains are ok in about half of the global checkpoints.
The working domains are shown ok almost instantly in all the checkpoints

Hi @Peter Debik

I have been doing DNS tests these past 48 hours and last night realized that all failling domains are finished in .com.mx .
Domains finishing in .com , .org, etc, are correctly propagated.

Any idea?

TIA
