Wake on LAN not working - NAS

Hi,

I have recently upgraded from LibreELEC v9 to v11, which went unexpectedly rather smooth, had a couple of issues, but nothing major.

However, I'm having an issue with trying to wake my NAS when Kodi starts. I did have Advanced Wake On Lan from mandark installed on v9 and this worked well, but is not supported on V11, so having to use the inbuilt Kodi wake on LAN feature and can't get it to work.

This is the wakeonlan.xml file configuration:-

<onaccesswakeup>
    <netinittimeout>20</netinittimeout>
    <netsettletime>500</netsettletime>
    <wakeup>
        <host>192.168.15.200</host>
        <mac>24:AB:BC:CD:11:DD</mac>
        <pingport>0</pingport>
        <pingmode>1</pingmode>
        <timeout>120</timeout>
        <waitonline>40</waitonline>
        <waitonline2>40</waitonline2>
        <waitservices>0</waitservices>
    </wakeup>
</onaccesswakeup>

Anyone got any ideas please?

Thanks
