[UNET] Client timeout on PC to XBox

Hi!

I have a wierd problem, I created a UNET demo scene to see if I can connect different platforms over LAN.
I have a NetworkManager and ServerBroadcast on both client and server setup.
Everything works flawlessly when server and client are PC or phone, but when I try to run the server on XBox (Dev mode) and the client on PC, I get the broadcast message from the XBox, but when I try to connect, I get Timeout

I tried to change the server port a few times, nothing changed
I tried to manually set the xbox ip and start the client, I still get timeout, so its probably not in the broadcasting

Any ideas? I'm really lost here

Thanks!
