• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Hi

I am setting DNSSEC up and are using a couple of online services to validate if everything is okay. One of the services are DNSViz | A DNS visualization tool - When I do it for a domain I get some errors:

RRSIG NSEC proving non-existence of MyDomain.tld/CDNSKEY alg 14, id 47160: The TTL of the RRset (10800) exceeds the value of the Original TTL field of the RRSIG RR covering it (7200). See RFC 4035, Sec. 2.2.

I can fix it by setting the Zone defaults TTL to 3 hours - but it seems more like a hack. Should the system not align the TTL for the RRset with the Zone defaults TTL?
 
I am not able to replicate this issue but then again I'm using Debian 12 instead of AlmaLinux. I'm wondering if this is something the registrar is doing?
