Aimaster, wol is not working

[Caktuz]

When trying to wake the nas with Aimaster i'm getting this error: send failed: invalid mac address?
It's not possible to change the mac address in Aimaster only the ip.
The wol works fine with other android wol apps.
If anyone know how to get it working please tell

I have faced this problem only one time before.

Finally, I have power off the NAS by the other phone or PC. Then change the IP of that NAS to another IP which must not be assign to another device before (I use DHCP with address reservation to reserve a permanent IP to that NAS). The problem doesn't appear again.

Thanks for your feedback.
I always use static ip for my nas, computer ect.
Waking up the nas from my computer works half the time, but from Aimaster it is a no-go.
