@Tom-Elliott Which information would help you to understand the problem more?

Secure Boot is disabled at the moment.

@sega I don’t know enough to answer your question intelligently.

I can tell you that for multicast imaging FOG uses the linux commands udpsend and udpreceive.

I don’t see any command line switches to pick which igmp mode is being used.

I can say its rare that there is ever a question on the revision of igmp being used.

@sega You can try something like this:

Sure it’s a help site, but it should be there to help out.

After many try&error runs, I managed to sign the files and to boot into the FOG menu with secure boot enabled. And I can deploy an image, register the host and do all the other things except boot from hard disk. Whenever I choose this option in the FOG menu he just goes back into the menu.
When I boot directly from the hard disk it works and also if I disable the secure boot option the FOG menu can boot from hard disk.

What could be the problem here? Oh and while I was troubeshooting I updated Ubuntu from 20.04 to 22.04 and FOG to 1.5.10

@sega Yes, though I think it’s specific to the multicast sessions bandwidth capability and limited at the storage node level (if my memory serves correctly)

I changed the code to PHP and now it works, so I think it was something security related from the browser.
