You may need to move the root of the tftp server to /grub to match the prefix assigned by the signed bootloader.
/etc/default/tftpd-hpa:
OPTIONS="-v -s /grub"
TFTP_DIRECTORY="/grub"
Can you see the grub.cfg file from grub?
grub> cat (tftp,10.10.1.13)/grub/grub.cfg
or
grub> cat (tftp,10.10.1.13)/grub.cfg
I also found it helpful for debugging the file to do the following:
grub> configfile (tftp,10.10.1.13)/grub/grub.cfg
error: can't find command 'kernel'
error: can't find command 'append'
...
You can use this to check the syntax for your file.
