Method 3: Checking and Adding Correct IP Address and Port

If the IP address that you are using is not a static one, it will change whenever the Internet Connection is reset. So follow the steps in order to check to add the IP address into Minecraft Launcher

  • Go to the search bar and type Command Prompt
  • Right-click on the icon and choose “Run as Administrator
  • Type ipconfig” and note down the “IPV4 Address
  • Also, Navigate to the “Minecraft Servers folder>Maxwell (some random numbers)> MinecraftServer” and open the “Server Properties” text document.
Checking and adding correct IP Address and Port 1
  • Note down the “Server Port” listed there. In our case it was “25565” it should be similar in most cases however in some it is not.
  • Now open up Minecraft and navigate to the “Play Multiplayer” option.
  • Select the server which you want to join by clicking on it and select “Edit” from the below options.
Checking and adding correct IP Address and Port 2
  • The server name can be according to your preference but the “Address” needs to be the IPV4 address that we noted and the port number for example “XXX.XXX.X.X:25565” the “25565” is the port number and it may vary.
Checking and adding correct IP Address and Port 3
  • Click on “Done“, click on “Refresh” and check to see if the issue persists.

Note – There are some applications that are generally incompatible with certain elements of Minecraft and cause issues with it. The list of applications is available here.
