How to Fix the Minecraft Connection Timed Out: Getsockopt Error

Getting hit with a “Connection timed out: getsockopt” error right when you’re trying to jump into a Minecraft session is genuinely annoying. Even more so when so many of the proposed fixes in video and step-by-step guides don’t do the trick.

The error has stumped plenty of players and the reason is that it can be caused by several different things. This guide covers all of them, with step-by-step instructions for each fix so you can work through them until you find the one that solves it for you.

What Causes the Getsockopt Error in Minecraft?

You’ll typically see the “Connection timed out: getsockopt” error when you’re attempting to join a multiplayer server or a LAN world. It usually appears when Minecraft’s Java client tries to communicate with your operating system to establish a network connection, but fails. 

The “getsockopt” in the error refers to a function used to retrieve information about a network socket. It’s essentially the mechanism Minecraft uses to check the status of its connection to a server. When that check fails or times out, you get this error. 

Although you don’t need to understand the technical details to fix it, knowing that it’s a network-level problem helps you focus your troubleshooting in the right place (i.e. your network and system settings).

Common Causes of Minecraft Connection Timeouts 

Before we get into the fixes, it helps to understand what might actually be causing the problem. The “connection timed out” error in Minecraft is essentially a Java network exception – it means your game tried to establish a connection with a server, waited for a response, and gave up after receiving nothing back.

There are a few reasons this can happen:

• Firewall blocks: This is the most common culprit. Windows Defender Firewall or third-party antivirus software may be blocking Minecraft’s Java executable (javaw.exe) from accessing the internet.
• Server-side issues: The server you’re trying to connect to might be offline, undergoing maintenance, or experiencing high traffic. If Mojang’s authentication servers are temporarily down, this can also prevent you from connecting.
• DNS problems: Your Domain Name System (DNS) translates server addresses into IP addresses your computer can use. If your DNS is slow, misconfigured, or returning outdated results, Minecraft may fail to connect to the server.
• ISP restrictions: Some internet service providers block certain ports or apply network policies that interfere with online gaming to maintain bandwidth and reduce the demands on the network at peak times.
• Incorrect server details: A small typo in the server IP address or port number of a server is enough to trigger a connection timeout. Minecraft Java Edition uses TCP port 25565 and any mismatch here will prevent a connection from being established.

Preliminary Troubleshooting Steps for Connection Timed Out in Minecraft

Before you start changing your network settings, it’s worth running through a few simpler checks first. These steps are less technical, but one of them might solve the problem before you need to dig into your network settings.

1. Check Your Internet Connection 

A weak or unstable internet connection is one of the most common reasons Minecraft fails to connect. If your connection drops or fluctuates while the game is trying to establish a session, you’ll get a timeout error.

Try opening a browser and loading a few different websites to confirm whether your internet is working. 

If pages are loading slowly or not at all, it’s likely that this is your issue. Restart your router by unplugging it for 30 seconds and plugging it back in, then try Minecraft again once it’s reconnected.

If your internet is still slow and Minecraft is still timing out, contact your ISP or use its status report webpage to determine if there’s a fault.

2. Check Minecraft Server Status 

If your internet is working fine, the problem might not be on your end. Mojang’s authentication servers occasionally go offline for maintenance, preventing players from connecting to multiplayer servers or Realms even when everything else is working perfectly.

You can check the current status of Minecraft’s servers via Downdetector or by checking the r/Minecraft subreddit, as players typically report outages quickly. 

If you’re connecting to a specific multiplayer server rather than Realms, also double-check that you’re using the correct IP address and port. For local servers, make sure you’re using localhost rather than an external IP.

Unfortunately, this isn’t a problem that you can solve yourself. If servers are down, all you can do is wait for Mojang to bring them back up.

3. Adjust Your Computer’s Date and Time

This one catches a lot of people off guard. Minecraft relies on secure connections that use your computer’s system clock to validate security certificates and authentication tokens. If your system date or time is incorrect, those certificates can appear expired or not yet valid, causing the connection handshake to fail and triggering a getsockopt error.

Setting your clock to update automatically fixes the mismatch and restores proper server communication. Here’s how to do it:

• Right-click on the clock in the bottom right corner of your taskbar.
• Select Adjust date and time.
• Ensure Set time zone automatically and Set time automatically are both toggled on.
• Below Additional settings, click Sync now.

4. Update or Reinstall Java

Minecraft Java Edition requires a specific version of Java to run correctly, and using an outdated version can cause network instability and connection failures. 

The official Minecraft Launcher automatically installs and manages the correct version of Java for you, but if you’re running a third-party launcher, you’ll need to manually install the correct version of Java.

Minecraft Java Edition 1.20.5 and above require Java 21. Earlier Minecraft versions, between 1.18 and 1.20.4, require Java 17. Game versions between 1.17 and 1.17.1 need Java 16.

5. Restart Your Computer and Router

It’s worth restarting your computer after every troubleshooting step you try to give your actions the best chances of success. 

Restarting your computer clears temporary files, resets network connections, and gives your computer a clean slate to work from. Restarting your router refreshes your connection to your ISP and clears any cached routing information that might be interfering with your connection.

To restart your router, simply unplug it from the power source, wait at least 30 seconds, then plug it back in. Wait for it to fully reconnect before launching Minecraft again.

6. Check for Minecraft Launcher Updates

An outdated Minecraft launcher can sometimes cause connection issues, as older versions may struggle to communicate properly with Mojang’s servers. 

The official Minecraft Launcher typically updates automatically, but it’s worth double-checking before diving into more complex fixes. To do this, simply open the Minecraft Launcher and check for any pending updates. If an update is available, install it and restart the launcher before trying to connect again.

7. Check Your Antivirus Software

Third-party antivirus software like Norton, McAfee, and AVG can block Minecraft’s connection independently of Windows Defender Firewall. 

If you’re running antivirus software, check its settings to see whether Minecraft or javaw.exe has been flagged or blocked, and add them to the exceptions list if so. The exact steps for doing this will vary depending on which antivirus program you’re using, so it’s best to refer to your software’s documentation if you’re unsure where to find these settings.

How to Fix Getsockopt in Minecraft

There isn’t a single fix-all action for when your connection timed out on Minecraft. What works will depend on what’s causing it in your specific setup. Go through the solutions below one at a time, and restart your computer after each one before testing your connection again.

1. Add Minecraft to Windows Defender Firewall Exceptions

Windows’ built-in security safety net, Windows Defender Firewall is designed to protect your computer by blocking applications it doesn’t recognise or trust. Sometimes it flags Minecraft’s Java executable and blocks it from accessing the internet without you knowing – especially after a game update. 

Adding Minecraft and Java to the list of firewall exceptions tells Windows to allow the connection:

1. Open the Start menu and search Windows Defender.
2. Open Windows Defender and click Windows Defender Firewall.
3. In the left-hand menu, click Allow an app or feature through Windows Defender Firewall.
4. In the menu, click Change settings.
5. Scroll through the list and look for Minecraft, Minecraft Launcher, and any entries for java, javaw, or javaw.exe.
6. For each entry you find, make sure both the Private and Public checkboxes are ticked.
7. Click OK to save your changes, then relaunch Minecraft and try connecting again

If you can’t find javaw.exe in the list, click Allow another app, then browse to your Java installation directory and add it manually.

2. Turn Windows Defender Firewall Off 

Turning your firewall off entirely helps you to test whether it’s the root cause of the problem. That said, doing this removes an important layer of protection from your computer and leaves it vulnerable to threats from the network.

Here’s how to turn your firewall off:

1. Open Windows Defender Firewall.
2. In the left-hand menu, click Turn Windows Defender Firewall on or off.
3. Under both Private network settings and Public network settings, select Turn off Windows Defender Firewall (not recommended).
4. Click OK to save your changes.

If turning off your firewall does resolve the connection issue, you might want to use a VPN while your firewall is disabled. It will encrypt your internet traffic and route it through a secure server, which adds back some of the protection you lose by disabling your firewall. 

Remember to turn your firewall back on again once you’re done playing.

3. Change Network Adapter Settings

If your firewall isn’t the issue, the problem might lie with your DNS settings. By default, your computer uses your ISP’s DNS servers, which can sometimes be slow, unreliable, or misconfigured. 

Switching to Google’s public DNS servers (8.8.8.8 and 8.8.4.4) gives your computer a faster and more reliable way to resolve server addresses, which can be enough to get Minecraft connecting again.

1. Open the Start menu and search for the Control Panel.
2. Click Network and Internet, then Network and Sharing Center.
3. In the left-hand menu, click Change adapter settings.
4. Right-click on your active Wi-Fi or Ethernet connection and select Properties.
5. Select Internet Protocol Version 4 (TCP/IPv4) from the list and click Properties.
6. Select Use the following DNS server addresses.
7. Enter 8.8.8.8 as the Preferred DNS server and 8.8.4.4 as the Alternate DNS server.
8. Click OK to save your changes.

4. Flush Your DNS

Even after switching to a new DNS server, your computer may still be holding onto outdated or corrupted DNS records in its cache. 

Flushing your DNS clears these stored records and forces your computer to look up server addresses fresh, which can resolve connection issues that persist even after changing your DNS settings.

1. Open the Start menu and search for Command Prompt, right-click on it and select Run as administrator.
2. In the window, type “ipconfig /flushdns” after C:\Windows\System32> and press Enter.
3. You should see the following confirmation messages: “Windows IP Configuration” and “Successfully flushed the DNS Resolver Cache”.
4. Type “exit” and press Enter to close the Command Prompt.

5. Reset Your IP Configuration

If flushing your DNS didn’t do the trick, resetting your IP configuration is the next step. This releases your current IP address and requests a fresh one from your router, which can resolve connection issues caused by an outdated or conflicting IP assignment.

Here’s how to do it:

1. Open Command Prompt as administrator (see the section above).
2. Type “ipconfig /release” and press Enter. You’ll see several messages noting that certain network adapters are disconnected.
3. Next, type “ipconfig /renew” and press Enter. Again, you may see similar messages about disconnected adapters.
4. Type “exit” and press Enter to close the Command Prompt.

6. Perform a Winsock Reset

The Windows Socket API (Winsock) is the component of Windows that handles communication between your computer and network services. If it becomes corrupted or misconfigured, which can happen after a failed network connection or a software update, it can prevent Minecraft from establishing a connection altogether. 

Resetting it restores Winsock to its default settings. This often resolves persistent connection issues that other solutions haven’t been able to fix:

1. Open Command Prompt as administrator (see section 4).
2. Type “netsh winsock reset” and press Enter. You should see the following confirmation message: Successfully reset the Winsock Catalog. You must restart the computer in order to complete the reset.
3. Type “exit” and press Enter to close the Command Prompt.
4. Restart your computer to complete the reset.

7. Check Your Port Forwarding Settings

If you’re hosting your own Minecraft server and other players are struggling to connect, the issue may be with your port forwarding settings. 

Port forwarding tells your router to direct incoming traffic on a specific port to the correct device on your network. Without it, connection requests from other players may never reach your server.

Minecraft Java Edition uses TCP port 25565 by default. If this port isn’t forwarded correctly in your router or VPN settings, players outside your local network won’t be able to connect. The exact steps for setting up port forwarding vary depending on the router or VPN you’re using, so it’s best to refer to your device or application’s documentation for specific instructions.
