UPDATE:  I did have to reach out to QuickBooks tech support for assistance and was bumped up 3 levels (which honestly happened pretty quickly) to get to someone who could help.  The tech (Dan) does not know why this situation existed, but the problem was with the Database Server Manager (QuickBooksDB).  It appeared to be installed and configured properly AND it was running as a Windows Service (Check Services to see if it is running).  However, when we opened QuickBooks Database Server Manager and checked the Port Monitor tab, there was no port listed for QuickBooks Database Manger 2023.  The solution was to Uninstall QB2023 and as a precaution, I also uninstalled QB2021 (our previous version), then re-installed QB2023.  I then opened QuickBooks Database Server Manager again, checked the Port Monitor tab and confirmed QuickBooks Database Manger 2023 was listed and active, then went to the Scan Folders tab and conducted a scan.  This resolved the issue.
