Update!
So I upgraded to Ubuntu 18.04 which did not resolve the issue. I then updated FOG to 1.5.9.71 which must have been release today 🙂 . After completing the FOG update, the services are running and I was able to successfully deploy 2 machines using multicast. I rebooted the server and verified that the services started after a reboot. Thanks for your help and working on this awesome software!
