I found the problem. Looks like when you upgrade from 13 to 14 it disables TFTP server. I have option 66 simply pointing to IP only. So when I tested HTTP it didn’t work either because I have to add “http://” as well as a port number for option 66 when using HTTP.
The fix was simple. Ether change provisioning to HTTP and update your option 66 or edit the file “etc/xinetd.d/tftp.rpmnew” to enable TFTP again.
