Wrong with My Reverse Lookup PTR Record

ptr-recordreverse-dnswindows-server-2016

I can't figure out why my PTR record does not work on my new server. This configuration worked on my old server and I already confirmed with my host that they added a record on their end so that 72.164.185.in-addr.arpa points to serer.copblaster.com but whenever I do a rDNS check of IP address 185.164.72.225 on MxToolBox or anything else it says no PTR record found.

As my screenshot clearly shows I have a basic reverse lookup zone with PTR record setup properly.

enter image description here

UPDATE: Does this info help at all?

C:\WINDOWS\system32>nslookup -debug -d2 -type=PTR 185.164.72.225

Reverse DNS records on the public DNS need to be added by your ISP that owns the IP address. PTR records added to your windows DNS server are typically not accessible on the public internet. Windows DNS is not typically your authoritative DNS server for your domain or PTR records. Windows DNS is usually used to host internal (to your LAN) DNS records and will either use root hints or forwarders to resolve external domains.

Please contact your ISP to update PTR records.
