Introduction

Minecraft is a popular sandbox video game that allows players to build and explore 3D worlds. One of the key features of Minecraft is its multiplayer mode, which enables players to join or create servers and play with friends. However, many players have encountered issues when trying to find and connect to local area network (LAN) servers. In this article, we will explore how Minecraft finds LAN servers and provide solutions to common problems.

What is UPnP and How Does it Relate to Minecraft?

UPnP (Universal Plug and Play) is a protocol that allows devices on a network to communicate with each other and access shared resources. In the context of Minecraft, UPnP is used to enable the game to discover and connect to LAN servers. When you enter "multiplayer" mode in Minecraft, the client says "Scanning LAN for Local Servers..." This is because the game is using UPnP to scan the network for available servers.

How Does Minecraft Use UPnP to Find LAN Servers?

When you enter "multiplayer" mode in Minecraft, the game sends a request to the UPnP server on your network to discover available servers. The UPnP server then responds with a list of available servers, which are typically running on a specific port (e.g. 25565). Minecraft then uses this information to connect to the available servers.

What is the Problem with UPnP and Minecraft?

Many players have reported issues with UPnP and Minecraft, including:

UPnP not enabled: If UPnP is not enabled on your router, Minecraft will not be able to discover LAN servers.
Port forwarding issues: If the port used by the Minecraft server is not forwarded to the correct IP address, Minecraft will not be able to connect to the server.
Firewall issues: If your firewall is blocking the port used by the Minecraft server, Minecraft will not be able to connect to the server.

Solutions to Common Problems

UPnP Not Enabled

If UPnP is not enabled on your router, you can enable it by following these steps:

Log in to your router's web interface.
Look for the "UPnP" or "Gaming" section.
Enable UPnP.
Save your changes.

Port Forwarding Issues

If you are experiencing port forwarding issues, you can try the following:

Check your router's port forwarding settings: Make sure that the port used by the Minecraft server is forwarded to the correct IP address.
Use a port forwarding tool: Tools like Port Forwarding or Port Forwarding Wizard can help you configure port forwarding settings.
Contact your ISP: If you are still experiencing issues, contact your ISP for assistance.

Firewall Issues

If you are experiencing firewall issues, you can try the following:

Check your firewall settings: Make sure that the port used by the Minecraft server is allowed through the firewall.
Add an exception: Add an exception to the firewall for the Minecraft server.
Contact your ISP: If you are still experiencing issues, contact your ISP for assistance.

Conclusion

Minecraft uses UPnP to discover and connect to LAN servers. However, many players have encountered issues with UPnP and Minecraft, including UPnP not enabled, port forwarding issues, and firewall issues. By following the solutions outlined in this article, you should be able to resolve these issues and enjoy playing Minecraft with your friends.
