Wake server when client starts

[Efficient_Good_5784]

I'm confused that everybody in this forum says that this thing is not working.
For me it works out of the box. My setup is similar to yours, I guess.

Waking up the Jellyfin server from a sleep state is possible, just not directly by the Jellyfin server itself when it's asleep.
OP states that he read WOL will not be implemented on the client side, so a 3rd party program will need to be used to send the wake packet to the server/computer.

In your case, it looks like your devices already handle this and wake your Windows PC just fine. Jellyfin isn't doing any of the waking up part, that would be your individual devices. All the clients do is search for a server to communicate with.
