I had this happen before to me, I took a computer to a friends house, and it wouldn't connect. I didn't look into fixing it though. Make sure it's the same version of Minecraft? Patching the launcher manually : Use this method only if you have problems using TheOnlyMrCat's solution. Thank you for this answer.

“I Can’t See the Minecraft Game on the LAN”

Btw it looks like the path for lsregister may change slightly depending on OS X version. Note, on dozens of Macs ranging from In the launcher, go into launch options and create a new profile. In the text box that highlights type in the following text at the end: -Djava. Much nicer than hacking the Info. I've added this as the recommended method to the troubleshooting steps. Don't forget to scroll down and hit Save after typing it in.

Note that "Advanced settings" needs to be enabled for JVM arguments. Then type that address into Direct Connect on the other laptop, and you've got yourself a friend XD Have fun! EDIT: Whups, forgot something. Example: IP Address On the Mac you want to host the computer his Esc and then select Open to LAN Then on the Mac you will be joining the game select Multiplayer from the main menu and you will see the game which you can then join.

Could you provide more detail on how Hamachi actually fixes this problem? Hamachi is used to simulate a LAN network over the internet.


While it's possible it would also work around the IP4 problems when Hamachi is used by two people on the same intranet, it is definitely overkill. Featured on Meta.

This is, far and away, the biggest problem people run into when setting up Minecraft on their local area network LAN : everyone has Minecraft installed and fired up, but one or more players cannot even see the the hosting player to connect in the first place. This problem arises because of confusion over exactly what is going on behind the scenes with the Windows Firewall.

How to Use the Publish Command in Minecraft

In the screenshot above you can see the specific wording of the Firewall popup. Most people will, by default, see the security alert, see Java and either not know what it is or just know enough about Java to recall hearing about what a security problem Java has been over the years and click cancel. Fortunately, the solution for this problem is simple, as long as you have administrative access to the PC meaning that the default account is the administrator or you have the password of the administrator account.

Second only to the Java problem is the different-network problem.

For the vast majority of home users this address will look something like Once you have the addresses of the different computers, check to see if they can reach each other over the network with the ping command. While still at the command prompt, enter the command ping [IP address of the host player's computer]. So, for example, if you have two compueters—one with the address The ping command will give you an output that tells you how fast it was able to connect to the other computer as well as how many of the individual packets were returned successfully.

Some routers have a security feature which is typically only applied to Wi-Fi users and not hardwired Ethernet users that isolates users from each other so that everyone can connect to the Internet but individual users cannot connect to each other. As such, you need to either check the port when you open the game on the host machine it is displayed on screen immediately after you open the game, as seen below or you need to look at the listing for the game on multiplayer screen of another client on your network that can successfully connect where it will list both the IP address and port number under the name of the open game.

Now, like in minecraft 1. This occurred at two houses. We both logged in and both of us had different minecraft accounts, one of the houses allowed the firewall thing, and even found the ip, and even typed "local Host" and still nothing came up. Also, we had the same minecraft versions. Should I just downgrade to like minecraft 1. It just says cannot connect to server. Please reply as soon as possible!

Once I enabled the home and the public, I had no problems connecting to each computer after that.
