Hello,

I am facing a problem with PXE Boot on my network. A client machine is trying to boot via PXE, but when booting from the FOG server, it displays the message “PXE over IPv4” and fails to load the image.

Environment Information:
FOG Server: Ubuntu 20.04 LTS, FOG version 1.5.x (it was working fine until recently).
Client Machines: DELL (the same machine that was working before).
Router: EdgeRouter (configured with options 66 and 67 for the FOG server).
Machine BIOS Settings: Secure Boot disabled, Fast Boot disabled, UEFI boot enabled.
Network: The client machine is on the same network/subnet as the FOG server, and there are no network changes, such as VLAN changes.
