I would hazard a guess that you’re sites are far enough away from the TFTP server that they’re timing out. I’m not sure where the documentation exists at this point, as it was just a user modification that did this and not something official, but you can set up remote TFTP servers (generally just add the TFTP service to a remote FOG node) and then use NFS to share the /tftpboot/pxelinux.cfg/ directory from the main site’s TFTP server to the node sites’ TFTP servers. If your issue is TFTP timeouts then that would take care of it.
