Answer 1

If you have successfully logged in to your game, you can sometimes still run into problems with communication between your computer/network and the server that you are trying to connect to.

Possible solutions are:

• Check that your network connection is enabled, and that no programs are blocking outgoing connections.
• Try disabling any existing firewall program, or changing its configuration options.
• Restart your modem/router.
• You may also want to try logging out of your account and then logging back in, as this refreshes your profile's authentication and connection with our servers.

It is also possible that this can occur when the Mojang servers are having difficulties processing requests. If you have tried the above solutions, please wait a bit and try your server login again later.

How to make a Minecraft server

At a very high level, making a Minecraft server follows a few basic steps:

1. Install the latest version of Java

2. Install the latest version of the Minecraft server software

3. Configure your server & network

4. Start the server

5. Check that your server is accessible

Things to keep in mind before you start.

Setting up a server takes some effort. You need a bit of technical know-how to properly configure a Minecraft server.

You should have a basic understanding of computer and networking concepts, which are fundamental to managing any kind of server.

Specifically, you should be comfortable and familiar with:

• Using the command line
• Networking (IP, DHCP, ports)
• Your system configuration
• Your network configuration
• Your router configuration (for home setups)

Running a Minecraft server from home?

You don’t need a top-of-the-line system to run a Minecraft server, but a desktop computer is ideal.

While you can run a Minecraft server and play on the same machine, you’ll need a more powerful system to do it.

And lastly, use a wired ethernet connection for your server instead of wireless. A wired connection is more reliable.

What if you don’t want to host your server at home?

Hosting any kind of server from home means you’re exposing your home network to the world.

If you’d rather not take that risk, then you can use a hosting provider instead. You’ll need to pay a monthly or annual fee, but you won’t have to deal with the hassle of managing the server hardware.

A GoDaddy Virtual Private Server is a good fit if you’re just getting started. Just keep in mind that you’re sharing hardware with other users, so keep an eye on resource usage.

If you need a little more oomp and you want to hook up a lot of players, you might try a dedicated server instead.

Make a Minecraft server on your Windows PC

1. Get the latest version of Java.

Open the Windows Control Panel. Under Programs, look for Java, and click Update Now.

Open a command prompt and enter java -version. You should see a version number.

2. Choose a location for your Minecraft server files.

Before you download the Minecraft server software, choose a location on your PC where you’d like to run the server from.

When you first run the server, it’ll create a few configuration files. It’s best to have all of these files stored in a dedicated folder.

You could place this folder on your Desktop, in your Documents folder, in your Programs folder, or anywhere else you’d like. It’s entirely up to you.

3. Download and start the Minecraft server software.

Download the server software from the Minecraft website. It comes as a Java .jar file. Save it to the location you chose in the previous step.

Double-click the .jar file to start the server. It’ll create the server configuration files, which need to be modified before the server is ready to use.

Accept the EULA: A text file called eula.txt was created. Open the file in a text editor and change eula=false to eula=true. Failing to accept the EULA will prevent you from starting the Minecraft server.

What if you see a “Can’t save server properties” error? Run the Minecraft server as an administrator by right-clicking the .jar file and selecting “Run as administrator”.

4. Enable port forwarding on your router.

Note: Port forwarding can be a security risk.

If you’re just hosting a server for players on your local network, you don’t need to worry about port forwarding. If, however, you want to make your server accessible to the world, you’ll need to enable port forwarding on your router.

For Minecraft, you’ll need to forward TCP port 25565.

You’ll also need to enter your server’s local IP address as the Output IP or Server IP for the forwarded port. This tells the router which device to point at. To find your server’s local IP, open the Terminal and enter ifconfig.

5. Start the Minecraft server.

Double-click the “start.command” file you created in step 3. A Terminal window will open. You’ll probably see error messages the first time you run the server. This is normal.

Once the server is running, you can invite others to connect to your server via your local IP address if they’re on your home network, or via your external/public IP address if they’re not on your home network.

You can find your public IP address by searching for “my ip address” on Google.

To check if your server is accessible, enter your public IP address into the Minecraft Server Status Checker.

Make a Minecraft server on a Linux host

If you’re not inclined to host a Minecraft server at home, you can spin up a Linux hosting plan to do it instead. This way you’re not responsible for managing any of the hardware, plus you’re not exposing your private home network to the public.

As mentioned before, a Linux VPS hosting plan from GoDaddy is a lightweight option if you’re experimenting or not expecting a lot of players to join your server. If, however, you’re expecting a lot of players, you should look at using a dedicated Linux server instead.

1. Install Java

While SSH’d into your host as the root user, enter the command:

    apt-cache search openjdk

This’ll list the available OpenJDK packages that can install Java. For this example we’ll select openjdk-7-jdk, which is the OpenJDK 7 Development Kit.

Update the list of available packages from the remote repositories:

    apt-get update

Then install the selected software package:

    apt-get install openjdk-7-jdk

Press “Y” when prompted to authorize the required storage space for installation. Once that’s done, verify that Java has been successfully installed:

    java -version

You should see the version of Java that has just been installed.

2. Create a location for your Minecraft server files.

Create a directory on your host where the Minecraft server files will be saved, then change to that directory.

    mkdir minecraft
    cd minecraft

3. Download the Minecraft server files.

Within the Minecraft directory, run the wget command to download the Minecraft server files:

    wget -O minecraft_server.jar https://s3

Next, we’ll need to install and run “screen”, so that your server continues to run even when you’re not connected:

    yum install screen
    screen

4. Start your Minecraft server.

java -Xmx512M -Xms512M -jar minecraft_server.jar nogui

(Tip: You can change the -Xmx and -Xms settings to adjust allocated memory for the Minecraft server. For example, you could enter -Xmx1G -Xmx1G to bump it up to 1GB of RAM. The available memory will depend on your hosting plan.)

To make sure everything is running correctly, stop your server with:

    stop

Then edit the “server.properties” file and set:

    enable-query=true

Save the “server.properties” file and restart your server. From there, enter your server IP address into the Minecraft Server Status Checker to see if it’s publicly accessible.

5. Point a domain at your Minecraft server.

Providing players with an easy-to-remember domain name instead of a complicated IP address makes it even easier for people to connect to your Minecraft server.

It’s super simple: Update your domain’s DNS records by adding an “A” record for your domain (using @ as hostname), or subdomain (using something like “mc” as the hostname), that points to your Minecraft server’s IP address.

Note that it can take up to ~24 hours for DNS changes to take effect globally.
