Environment

Release: 8.x

Cause

Priority of server names in the communication profile!

Resolution

In the Notification Server communication profile, there were 2 addresses for HTTPS Communication Hosts.

One with the FQDN name and one with the DNS name (Server's Alternative name); after changing the priority and bringing the DNS name first, the issue is resolved.
