Many Minecraft players have the problem that the local Minecraft network doesn’t work when they want to play locally with their friends. And as frustrating and annoying as it is, fortunately it can be fixed. Here’s how:

1. Temporarily disabling antivirus

2. Make sure you have enabled network discovery

3. Make sure each computer is connected to the same network.

4. Make sure all players are using the same version of Minecraft.

5. Make sure all participants have the same IP address.

6. Try a direct connection

7. Try playing without mods

8. Reassemble the tank

What doesn’t work on Minecraft LAN?

LAN (Local Area Network) is used, for example, to connect multiple computers in a local area. B. in a school, university, residential complex, etc. The connection is made via an Ethernet cable or via W-LAN connections.

For those who play Minecraft on Windows, it is very common to encounter an error, such as B. that the local network cannot be used, or cannot be used at all.

However, this does not mean that your device is not connected to the internet, just that Minecraft cannot use the local network to connect to other devices.

It’s very frustrating and it spoils the mood. But all you have to do is go to the control panel, access the Windows Defender firewall and allow it to allow access to Minecraft by checking the private and public sections for Java.exe or Java(TM)….. check. This solves the problem of the local network not working 90% of the time. However, if the problem is still not solved, try one of the methods in Troubleshooting.

Details about enabling Java in the firewall

The Windows firewall does not allow Minecraft to use the Internet unless the user gives permission. However, it would be logical to expect a popup request for access to Minecraft. But it’s not. Minecraft is actually a Java file, and to access the internet you need to enable Java.

If you don’t get that popup, here’s what to do.

Step one: Open the control panel. You can search in the Windows search bar

Step two: Click system and security

Step three: Click on the Windows Defender Firewall

Step four: Click the Allow Application or Function button through the Windows Defender Firewall.

Step Five: Select the private and public columns for JAVA and click OK.

Check the LAN connection. If this still does not work, disable the firewall and try again.

Other corrections

1. Temporarily disabling antivirus

The antivirus program on your device may interfere and affect your LAN connection. Even if it’s risky, temporarily disabling it can help solve the problem.

You can disable it by searching for your antivirus in the search bar and then disabling it for an hour or two while you play.

2. Make sure you have enabled network discovery

In order for your local network to work in Minecraft multiplayer mode, you must allow network discovery on your computer. That’s the way to do it,

Step one: Search for advanced sharing settings in the Windows search box

Step two: Click the Manage advanced sharing settings button.

Step three: Click on the Enable Network Discovery button

Step four: Click on Save Changes

3. Make sure each computer is connected to the same network.

If all devices that want to connect are not connected to the same network, there will be a LAN connection problem.

This problem is especially acute in places where you need to connect via wifi, because one device may be connected to wifi at home, while another device is connected to a free wifi nearby or to a neighbor’s wifi that you may have used once.

Therefore, make sure that all devices have the same internet connection.

4. Make sure all players are using the same version of Minecraft.

If the client player and the host player are using different versions of the game, there is a bounce, i.e. the connection is first established and then broken again, with a similar message:

To do this, the host must update the version number of the player’s Minecraft client. To do this, launch the Minecraft Launcher on the client machine and click Edit Profile. Select the appropriate version of Minecraft from the Use Version drop-down menu.

5. Make sure all participants have the same IP address.

If one device is connected with a wireless connection and the other with a wired connection, the two devices will have different IP addresses. Therefore, make sure that all devices are connected to a wireless or wired connection.

Another problem is the isolation of the PA. This is the configuration of the wireless router. When enabled, this setting prevents a device connected to the network via a wireless connection from accessing resources connected to the same network via a wired connection.

Therefore, we need to deactivate the isolation of the access points. That’s the way to do it:

Step one: Open the command line. You can search for cmd in the search bar

Step two: Type ipconfig and hit the Enter key. You will then see a list. The IPv4 address is your IP address, and that’s what you need.

Step three: After entering the IP address in the URL bar, call up the router’s configuration page.

Step four: Search for Wireless AP Enabled or Access Point Isolation from each description. The Wireless Configuration tab of the router’s browser configuration page typically contains settings for isolating the access point.

Step Five: Uncheck the check box to configure your router’s AP isolation.

Step six: Restart the router after disabling the AP isolation.

Step seven: If you are not the host, tell the host to check their own AP isolation configuration as described above.

6. Try a direct connection

You can also opt for a direct connection. For this, you will need the IP address of your host computer, which you can obtain by following the previous steps.

Once you have the IP address, you’ll need the game port you get when you start Minecraft on the host computer at the bottom of the screen.

Click on Direct Connect, enter the IP address and game port when making the LAN connection, and you’re ready to go.

7. Try playing without mods

Models can be very attractive because they can give the player a different look in the game. However, mods can also disrupt the multiplayer experience and cause Minecraft LAN to fail. So try playing without mods and that should solve the problem.

8. Reassemble the tank

If all else fails, you still have hope of reinstalling Minecraft and logging back in for multiplayer. Hopefully this will fix the LAN issue that isn’t working, and you can continue your Minecraft adventure.

The problems listed here are the most common problems players face. Especially the Windows firewall. Usually players keep getting java popups that they keep canceling because they think it has nothing to do with Minecraft.

If it’s not a firewall, it would certainly be one of the problems for which a solution was given above.
