tftp transaction in UEFI shell states "too few arguments"

Hello, I am an ultra-beginner to UEFI world.
I was trying to setup a way to transfer the files from a server (running Linux) to a client setup (running UEFI shell).
I was able to ping server's IP address from the client setup and vice-versa.
I installed tftpserver on server.

Code:[~ || $> cat /etc/default/tftpd-hpa
/etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/srv/tftp"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure"And I have a file abc.txt in /srv/tftp.

Code:[~ || $> ls /srv/tftp
abc.txtFrom UEFI shell of client, I am trying to download the file from server.
And I have `tftp.efi` created in UEFI shell of client setup.

Code:FS0:\network\> ls
Directory of: FS0:\network\
05/03/2024 14:39 <DIR> 16,384 .
05/02/2024 16:45 <DIR> 0 ..

tftp: Too few argumentsFor some reason, this error does not go away.
I tried other options mentioned in `tftp -?` but in vain.
Any help to break-through is highly appreciated. Thank you!
