@sebastian-roth Also, when we changed the subnet of the FOG server we didn’t create a new Server. I changed the IP values inside our original FOG server and reran the FOG Installer for the IP addresses to be changed throughout. After I ran the installer, I didn’t do anything with the certs inside the FOG server.

Thank you both for your help! George and I were messaging back and forth and my DHCP policies and scopes were pretty messed up. Looking back I have no idea how it worked before. After completely changing them the machines are booting into FOG again just fine. Appreciate the quick responses!
