@george1421 I do not have 2 DHCP servers. I have a DHCP server, and a Relay that points at it. I did find the solution to my issue. The LAGG configuration between my 2 Juniper EX4600 switches got messed up. Only some traffic would pass, and not everything. After correcting the issue, I am all good now. Thank you all for the help.
Cheers! 
@george1421 I did already check the traffic using the monitor function of my Palo Alto. Everything looks good. Plus this just worked a few hours earlier. Thanks for the help. I know I probably have a very weird situation.
@george1421 Thanks for the reply. I am running the isc-dhcp server that you can install via the installfog.sh script. It is running on the Fog Server. Configuration is:
# DHCP Server Configuration file\n#see /usr/share/doc/dhcp*/dhcpd.conf.sample
# This file was created by FOG
#Definition of PXE-specific options
# Code 1: Multicast IP Address of bootfile
# Code 2: UDP Port that client should monitor for MTFTP Responses
# Code 3: UDP Port that MTFTP servers are using to listen for MTFTP requests
# Code 4: Number of seconds a client must listen for activity before trying
# to start a new MTFTP transfer
# Code 5: Number of seconds a client must listen before trying to restart
# a MTFTP transfer

I’m having issues with UEFI boot on 1.5.9. I am using FOG as a dhcp server on the vlan I created for imaging. I do have dhcp-relay setup on my Palo Alto firewall. Devices can legacy boot to the server, but not UEFI. I just captured an image using UEFI only a few hours ago, so it was working. Now that I tried to deploy that same image, machines can’t boot to the server. Please help, and thanks in advance!
Can’t upload. I get an error about the maximum image size. Uploaded to google drive. Link is: https://drive.google.com/file/d/1QLr-bUJX0TSAN_K9MQpaB9l_HIN8rqbn/view?usp=sharing
Issue getting clients to boot. This ipxe error is thrown, and then it states chainloading failed. I am running fog server 1.5.9 and using tls. Any ideas?
Thanks, you can mark this as solved. Updated client worked beautifully. Thank you all so much!!
When I attempt to install FOG Client, it returns an error. “Unable to Install CA Cert.” This occurs when the server is setup for HTTPS, and the client installer is checked for HTTPS. I have tried googling this issue with no avail. Any assistance is greatly appreciated.
I was informed it was due to the ssl certificate not being trusted.
When I install FOG 1.5.9 and select HTTPS enabled for install, client devices show boot.php Premission denied during boot. Any assistance?
