PXE-E18: Server response timeout

  • Hi, I was working with fog recently and for few days everything worked fine.
    I could capture/deploy images, but today I “finished” work so I thought that I’ll delete all hosts because I don’t need them now… Later when I booted up laptop to PXE I can see this:

    TBH I have no clue what happened - I reinstalled FOG and PFSense and it’s still the same.
    I’ll send tcpdump tommorow when I’ll have acces to machine
