[syslinux] tftp problems

[Ray McCaffity]

Hello,
   I am a fairly experienced user.  I have set up tftp in the past at various times, although it's been a few years.
I am using version...
Version      : 5.2
Release      : 37.el9

On AlmaLinux 9.3, I currently have SELinux disabled.
]# firewall-cmd --list-services
cockpit dhcp dhcpv6-client http ssh tftp

I have tftp enabled on the firewall.  ( I have tried with the firewall completely disabled also )
I can get a file locally on the tftp server, as any user, even non-root.I cannot get any file remotely from any other system.  These are all Linux systems running either Fedora 39 or Alma 9.3
I get the same results on a Fedora 39 system, also with tftp-server installed.
This is the message from any client.

These are my systemd service files.

I have searched several web pages all over the web, but most have examples for either a/etc/xinetd/tftp-hpa file, or a /etc/default/tftp file.  I do not have either of these.
