The server's host name doesn't resolve to external IP Address, yet all records are fine on nslookup and mxtoolbox no changes made and clearly worked for months proir to Oct. 18, 2024
Glad to hear I’m not alone (mixed feelings). Had been scratching my head as there’s been no DNS or firewall changes.
I'm on Server 5.2 and the same thing. Xfinity (both residential & business) was busy "enhancing [my] network" in October and I noticed this. It must be some kind of new security measure on the network side that doesn't let old software like MacOS Server 5 scan for service availability.
I've got this same issue and now, also, I can't get Server App to update Apple Push Notifications certificates…
Has anyone seen or heard anymore about this?
Reachability on mac server app 5.6.3
