If you’re trying to play Minecraft and suddenly get hit with the “Connection Timed Out – getsockopt” error, you’re not alone. This frustrating issue typically occurs when Minecraft is blocked from connecting to the server due to DNS problems, Windows Firewall restrictions, or incorrect network settings.

In this guide, you’ll learn what the ‘getsockopt’ error means and how to fix it with a few simple steps—no tech wizardry required.

🔍 What is the ‘getsockopt’ Error in Minecraft?

The “getsockopt: connection timed out” error in Minecraft generally means that the game is unable to connect to a server. The term “getsockopt” refers to a socket-level network function used in the background to establish communication between your game and the server. When this function fails due to network misconfiguration or blocks, Minecraft displays this error.

Common causes include:

  • Incorrect DNS settings
  • A firewall blocking Minecraft or Java
  • Network congestion or poor connection
  • Outdated network cache

Let’s walk through how to fix this.

✅ Step-by-Step Fixes for Minecraft getsockopt Error

🧹 1. Flush Your DNS Cache

Corrupted DNS records can interfere with Minecraft’s ability to connect to external servers.

How to do it:

  1. Click Start, search for CMD
  2. Right-click Command Prompt → select Run as administrator
  3. In the command window, type: 
    ipconfig /flushdns
  4. Press Enter
  5. You should see a message saying: “Successfully flushed the DNS Resolver Cache.”

This clears outdated DNS records and allows a fresh connection attempt.

🌐 2. Change Your DNS Server to Google DNS

Your Internet Service Provider’s (ISP) DNS servers may be slow or unreliable.

Switch to a public DNS like Google’s:

  1. Open Control Panel
  2. Set View by: Large icons
  3. Click Network and Sharing Center
  4. On the left, click Change adapter settings
  5. Right-click on your active network (e.g., Wi-Fi) → Select Properties
  6. Click on Internet Protocol Version 4 (TCP/IPv4) → Click Properties
  7. At the bottom, select: Use the following DNS server addresses
  8. Enter the following: 
    Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4
  9. Click OK and close all windows

These Google DNS servers are fast and reliable for most users.

🔥 3. Allow Minecraft and Java Through Windows Firewall

Windows Defender Firewall might be silently blocking Minecraft or Java.

Here’s how to unblock them:

  1. Click Start, search for Windows Defender Firewall
  2. On the left, click Allow an app or feature through Windows Defender Firewall
  3. Click Change settings (top right)
  4. Scroll down and find both Minecraft and Minecraft Launcher
    • Ensure both Private and Public are checked
  5. Also, look for Java or javaw.exe
    • If found, check both Private and Public for Java as well
  6. Click OK to save changes

✅ If Minecraft or Java isn’t listed, click Allow another app → locate their .exe files → and add them manually.

🔁 4. Restart Minecraft and Try Again

After applying all the changes:

  • Restart your PC
  • Launch Minecraft
  • Try connecting to the server again

The error should now be resolved.

📌 Bonus Tips If You’re Still Having Issues

  • Ensure you’re using the latest version of Minecraft
  • Temporarily disable any third-party antivirus or firewall to test connection
  • Try connecting to the server with a VPN to see if your ISP is causing the block
  • Reboot your router or switch to a wired Ethernet connection

🧠 Final Thoughts

The Minecraft getsockopt error might look intimidating, but it’s usually the result of a minor network or firewall misconfiguration. By following the practical steps in this guide—clearing DNS, adjusting firewall rules, and updating your network settings—you’ll likely get back to your Minecraft world in just a few minutes.

✅ Quick Fix Recap:

  • Flush DNS via Command Prompt
  • Switch to Google DNS (8.8.8.8 / 8.8.4.4)
  • Allow Minecraft & Java through Windows Firewall
  • Restart and reconnect
