WOL is a non-sense for a server, this is why it’s ignored since 6 years and will never be, so I down-vote the WOL feature. You should have your connexion always UP, and computer sleeping. This is possible. Cf. Wake on LAN (WOL) for Windows 10 PLEX Media Server when in sleep mode. Is it possible?
ARP address is aging in switch and there is only reality distortion to maintain the table. Plus some switches with energy saving that shut the port and destroy your magic WOL packet. Solution vendor based on WOL just lie to you as it’s not 100% reliable event on LAN. There is too much reasons to have WOL not working.
