Nope. The same. Just lost all LIFX. Will wait they will reappear.

Under switch control, is jumbo frames enabled? If so disable it.
Sorry to hear that. I would revert the changes that I suggested.
It is disable.

Yeah I doubt it would have done anything to help but making sure it was off for HE (HE doesn't deal well with jumbo frames)
That said it's still a strange issue. I have several lifx bulbs and they never do that. @bcopeland and suggestions for @JM4522 ??
@aaiyar @rlithgow1 thanks for your advices and clues. Everything I was reading after your comments pointed to the multicast mode... again. So I couldnt believe what @aaiyar suggested me to do didnt have any impact.... After more reading, just did another test this morning after making sure that IGMP was on (even if I did the test yesterday):
Rebooted HE and I now have Lifx discovered immediatly. I really dont know what happened yesterday. Either a Snafu or a Code 18...
In anycase I'll monitor it again but it looks this setting change had an effect
Thanks for everyone support in leading me in the right direction.

multicast is definitely needed for lan integrations like that (this includes homekit) So glad you got it running!!!!!!
Well - I was 12 days without rebooting. Did a reboot after upgrating to the latest version - Problem is still there unfortunately.
Hitting Refresh will sometime force a discovery sometime not - Just need to wait and eventually they show up
