Wake on Lan stop working on i5NUC

Suddenly last week my ROCK server stop responding to WOL send by Asus app or from Asus Web GUI.
Any idea why?
thanks

Hello @MPV,

I’ve moved your post to #tinkering for visibility.

WoL happens at the BIOS level, “below” ROCK/RoonOS. It’s likely a configuration mishap in the NUC’s BIOS or on the network.

Thanks John, but I did not touch any bios settings. My Asus Aimesh was not changed either……just regular updates.

Any other idea?
