If you use a Windows PC and are hosting your single-player world on your home Internet via Local Area Network (LAN), but a Timeout error occurs when your friend tries to connect to it, you may need to change your Windows Network profile settings from Public to Private. This will allow other Minecraft players to connect to your world via Home network LAN.
Change your Windows Network profile to Private
- Close Minecraft.
- Right-click your Internet connection icon (the wireless connection or network icon in the System Tray) and select Network & Internet settings.
- Select Properties for your Home Network connection.
- Under Network Profile Type, change the type from Public to Private.
- Start Minecraft, load your world, and click Open to LAN.
- Your friends should now be able to join your world from the Play Multiplayer screen!
Note: The Public profile is used for networks that you cannot trust, such as free Wi-Fi at a café. It is not recommended to change this setting if you are connected to a public network that you cannot trust.
