LAN Deauth
This modification solves the authentication problem for local LAN servers. It automatically disables the "online-mode" setting, which prevents the "Authentication servers are down for maintenance" error from appearing for players joining your world.
Important feature - for the mod to work, it only needs to be installed by the hosting player. Other participants can join without additional modifications.
How it works: When you start the game, you see the IP address and port in the information about the created world. Use this data for direct connection, since LAN games may not appear in the list of available ones.
