Minecraft: java.net.connectexception no further information. Me and my girlfriend get this error when we try joining each other's lan worlds

As stated in the title, we get the error Minecraft: java.net.connectexception whenever we try to connect to each other’s LAN worlds. We have tried several fixes including:

  • Using Hamachi
  • Turning off our firewalls
  • Creating new inbound rules for Minecraft
  • Installing a different version of Minecraft

Nothing so far has worked. We can connect to other servers just fine, but can never join each other’s LAN worlds.

    I believe that this is probably a firewall problem. Have both of your computers have firewall disabled on both public and home networks? My sister and I tried this after going days without being able to play lan and it worked but if you do not wish to do this then here is a way to let programs through your firewall, not ports. And also realise that Minecraft now has built in Java so please post the executable path in the launcher’s edit profile section. So to begin go to the start menu and paste this in:

    Control Panel\System and Security\Windows Firewall\Allowed Programs
    

    Then click change settings:

    Allow Programs section

    Then press allow another program…:

    And then what you must do is paste what is in your executable which you found in the Minecraft launcher:
    Executable Location
    .
    And then click add. I hope this help’s you

    My brother and I had the same problem. I couldn’t connect to his server and we used the exact same programs.

    Here’s the solution: swap roles, have whoever is hosting at the moment try letting the other person try hosting instead.

    We tried this, so now I’m hosting. Now, my brother and I can finally play together.

    We love Playing Games, especially Video Games.
