Minecraft Server Unknown Host Fix: A Comprehensive Guide for Devs

Are you encountering the “unknown host” error message when trying to connect to your Minecraft server? If so, you’re not alone. Many developers have faced this issue, which can be frustrating and time-consuming to troubleshoot. However, fear not, as we’ve compiled a comprehensive guide to help you fix the Minecraft server unknown host issue once and for all.

What is the Unknown Host Error in Minecraft?

The Minecraft unknown host error is a networking-related problem that occurs when your Minecraft client cannot connect to the server due to an incorrect or non-existent server address. The error message usually looks like this:

java.net.UnknownHostException: servername.com

This error can have several causes, such as incorrect DNS settings, a typo in the server address, or issues with your internet connection. However, the good news is that these issues can usually be resolved with a few simple steps.

How to Fix Minecraft Server Unknown Host Error

Here are some steps you can take to fix the Minecraft server unknown host error:

Step 1: Check Your Server Address

The first thing you should do when encountering the unknown host error is to verify that your server address is correct. This is especially important if you have recently changed your server’s domain name or IP address.

To check your server address, open your Minecraft client and go to the Multiplayer tab. Look for your server and click on the Edit button. Check that the address is correct and does not contain any typos or errors.

Step 2: Check Your DNS Settings

If your server address is correct, the next thing to check is your DNS settings. DNS (Domain Name System) is the service that translates domain names into IP addresses, allowing your computer to connect to websites and servers.

To check your DNS settings, go to your computer’s network settings and look for the DNS server address. You can also try using a public DNS server, such as Google DNS (8.8.8.8), to see if this resolves the issue.

Step 3: Check Your Firewall and Router Settings

Your firewall and router settings can also cause the Minecraft server unknown host error. These settings can block the connection between your Minecraft client and the server, preventing you from connecting.

To check your firewall and router settings, make sure that Minecraft is allowed through your firewall and that any port forwarding rules for your server are set up correctly. You can also try temporarily disabling your firewall to see if this resolves the issue.

Step 4: Check Your Internet Connection

If none of the above steps resolve the issue, the problem may be with your internet connection. A slow or unstable connection can cause connection issues and prevent your Minecraft client from connecting to the server.

To check your internet connection, try running a speed test or contacting your internet service provider (ISP) for assistance.
