DHCP/PXE Stopped Working

[dpotesta50]

Running the Fog 1.5 on top of Ubuntu 16.04. Everything was working perfectly fine but today I can’t get a laptop to PXE boot to the server anymore. Says NO DHCP or proxyDHCP offers were received. This was literally working perfectly fine on Friday. No changes were made, now it’s not working.
What do I check?

what device is providing your dhcp or proxydhcp services?
