Wake on lan not working from osmc/vero4k

I have setup some NFS shares, and configured Settings/System/Power saving “try to wakeup remote servers on access”
This does not work from osmc, but it works from either my freebox, or manually using the wakeonlan commandline.
What’s going on ?
Thanks.
Using osmc 2019.04-1 on a vero 4k.

Without debug enabled logs demonstrating the issue, there is no way for anyone to speculate.

A debug log will allow us to see if Kodi is trying to at least send the WOL signal.
