A Java LAN world can be joined by another Java client on the same local network while the host keeps that world open.
Quick answer
Confirm both players use compatible editions and versions. Then check account permissions, host status, console subscription requirements, and network reachability.
What to do
Work through these checks in order. Stop if a menu, command, or world state differs from the conditions described.
- Confirm your Minecraft edition and release, then identify the world, device, or server involved.
- Use Open to LAN on the host and record the port shown in chat.
- On the other device, use the LAN list or the host’s local IP and current port.
- Check the result in the game. If it differs, record the exact error or menu label and compare the official source for your version.
Edition and version differences
Java and Bedrock have different join flows. Account permissions, console services, host availability, and network conditions can also change the result.
If the result differs
Compare the current screen or error text with the conditions above. Confirm both players use compatible editions and versions. Then check account permissions, host status, console subscription requirements, and network reachability. Change one variable at a time so you can tell which step made a difference.
