Sorry if this topic is already solved but I can´t find it in the forum. Basically I can't create a private world, when i tryed to create it this message pops up: "can't connect with the server"
This has already been answered a few times just use the search feature.
I am not entirely sure if this will fix your issue but its worth a try.
go to your install folder: "...\life is feudal your own\" delete the "daemon" folder and have steam re-verify the file integrity and you might be good to go, if not keep searching the forums
