Unable to download a file from local tftp daemon (atftp) [solved]

I setup a simple tftp server on my workstation using atftp.  I placed a test file in /srv/atftp/ and started the service.  I am unable to download the file connecting from the same machine as a test.  Wondering what I am doing wrong.

% ls -lh /srv/atftp 
total 7.8M
-rw-r--r-- 1 atftp atftp 7.8M Nov  5 12:25 initramfs.bin

% atftp --trace --verbose -g -l initramfs.bin 10.9.8.245
Trace mode on.
Verbose mode on.
sent RRQ <file: , mode: octet <>>
received 1. DATA <block: 1, size 0>, update last received block: 0 → 1
sent ACK <block: 1>

That makes a 0-byte file named initramfs.bin

On the server:

% journalctl -f -u atftpd
Nov 07 11:05:47 workbench atftpd[1384]: socket may listen on any address, including broadcast
Nov 07 11:05:47 workbench atftpd[1384]: Serving  to 10.9.8.245:60760

Nov 07 11:05:47 workbench atftpd[1384]: tftpd_file.c: 1178: recvfrom: Connection refused
Nov 07 11:05:47 workbench atftpd[1384]: Server thread exiting
Nov 07 11:06:20 workbench atftpd[1384]: socket may listen on any address, including broadcast
Nov 07 11:06:20 workbench atftpd[1384]: Serving  to 10.9.8.245:39852
Nov 07 11:06:20 workbench atftpd[1384]: recvmsg: Connection refused
Nov 07 11:06:20 workbench atftpd[1384]: tftpd_file.c: 1178: recvfrom: Connection refused
Nov 07 11:06:20 workbench atftpd[1384]: Server thread exiting

EDIT: it works if I invoke it in interactive mode... must be bad syntax with the flags.

% % atftp --verbose 10.9.8.245 
Verbose mode on.
tftp> get initramfs.bin
###  the file is successfully downloaded
tftp> quit

Maybe a stupid suggestion, but don't you want -r rather than -l?
