Write the Server IP Address Correctly

You should first check whether you’ve written the server IP address correctly when you see this error. Contact the server owner or hosting company if you’re unsure what the IP address is. Sometimes, Minecraft servers change their IP addresses, so your address may no longer be valid. When this is the case, the server will usually be able to tell you where they moved their services and give you a new IP address.

You can also search for the server’s name in Google with IP to find if there are any common problems with people who play on that server.

The problem could also be related to your router configuration, especially if you don’t know how to enter public IP addresses into your router settings manually. Ensure you enter all the information into your router correctly, including your DNS information, and make sure DHCP is enabled on your network device.

If none of this work, try restarting your PC/router and uninstalling and reinstalling Java by downloading an offline installer package from Oracle’s website. Once installed, ensure all other programs are closed before opening Minecraft again and connecting to a server.

Disable Firewall for Minecraft

  • Open the Start menu and search for Control Panel.
  • Click on System and Security.
  • Click on Windows Firewall.
  • Choose the Windows Firewall on or off link.
  • Select the Turn off Windows Firewall option for private and public networks.
  • Tap OK to save your changes.
  • Restart Minecraft and check to see if the issue has been resolved.

  • Select Properties from the drop-down menu

In Properties, double-click Internet Protocol Version 4 (TCP/IPv4), which will open another window where you should see two fields below IP Address – one with Obtain an IP address automatically selected and another with Use the following IP address empty.

Select Use the following IP address, then enter the IP address of your DNS server in both fields (usually After typing in the second field, click OK twice to save these changes and close both windows. You may also set up a backup DNS server just in case by adding it in the third field as well if your ISP provides you with more than one.

Clear DNS Cache

You may see that Minecraft can’t resolve the hostname error because your DNS cache is full. If this happens, your computer will have trouble connecting to Minecraft servers. To fix this, you can clear your DNS cache. Here’s how to clear DNS cache in Windows 8 or 7:

  • Open up a command prompt as an administrator by pressing Windows+X on your keyboard and then clicking Command Prompt (Admin). Type ipconfig /flushdns and press enter.
  • Now type ipconfig /registerdns into the command prompt window and press enter. A confirmation message reading, “Successfully flushed the DNS Resolver Cache.” Will display.
  • Close all windows on your computer, including Command Prompt, if it’s still open. Restart the system so these changes can take effect, and try connecting to Minecraft again.

Ensure You Use the Right Hostname of the Server

The most common reason for the Minecraft Can’t resolve hostname error is because you’re using the wrong hostname for the server. The hostname is the address players use to connect to the server, so it’s important to be entered correctly. If you’re not sure what the hostname of your server is, you can find it in the Server Settings tab of the control panel.

Once you have the correct hostname, simply enter it into the Connect to Server dialog box and click Join Server. If you continue to have trouble connecting, use the valid port number. The default port for Minecraft servers is 25565, but some servers use a different port. You can check the port number in the Server Settings tab as well.

Check Server Problem

You may see Minecraft can’t resolve the hostname error because of a problem with the server you’re trying to connect to. This could result from the server being down or experiencing technical difficulties. If you can connect to other servers without issue, then it’s likely that the problem lies with the server you’re trying to connect to.

To fix this, you’ll need to contact the server owner or administrator and let them know about the problem. You should also include your IP address so they can identify what might be going on with your connection.
