Connection issues can ruin an otherwise thrilling gaming session, especially in games like No Man’s Sky (NMS) where exploration and multiplayer interaction are key components. One of the more frustrating problems gamers often encounter is the “You Have Lost Connection” error message. This usually appears when the game fails to maintain a stable link with the servers, resulting in limited or no multiplayer functionality.
TL;DR
If you’re encountering the “You Have Lost Connection” error in No Man’s Sky, it’s usually related to network problems, outdated files, or in-game server hiccups. Quick fixes include restarting the game, resetting your router, ensuring your ports are open, or verifying game files. A few easy troubleshooting steps can often restore seamless gameplay without delving into complex solutions.
Understanding the Error
The “You Have Lost Connection” error in NMS typically crops up when the game’s connection to its servers is unstable or broken. This can affect multiplayer features, such as joining friends, using the Space Anomaly, or even updating your discoveries to the Universal Atlas.
Before you start changing settings or reinstalling the game, it’s essential to determine whether the issue is local to your setup or caused by Hello Games’ servers.
1. Check the Server Status
Your very first step should always be checking whether the problem is on your end or theirs.
- Visit PlayStation Network Status or Xbox Live Status if you’re using a console.
- For PC players, NMS uses Steam services, so check Steam Status.
- Also, the official Hello Games Twitter account often updates players during outages.
If servers are down, there’s nothing to fix on your end—just sit tight until service is restored.
2. Quick Local Network Resets
Sometimes, all it takes is a simple network refresh to reconnect successfully.
- Restart your game. Close No Man’s Sky completely and reopen it. This alone can fix transient connection issues.
- Power cycle your router/modem. Turn off your networking equipment for 30 seconds, then power it back on.
- Switch from Wi-Fi to Ethernet. A cable connection is generally more stable and can drastically improve network consistency.
3. Check Your NAT Type
NAT (Network Address Translation) settings affect how your console or PC connects to other players. A Strict NAT type can block multiplayer functionality, while a Moderate or Open NAT is more favorable.
- On PC: Use the Xbox Game Bar or type
cmdin Windows and useipconfigfollowed bynetstat -anto check port statuses. - On console: You’ll find your NAT type listed under network settings.
To change your NAT type:
- Enable UPnP in your router settings.
- If that fails, manually open the required ports for NMS:
- UDP: 3074 (common Xbox Live/PlayStation ports)
- TCP/UDP: 27015–27030 (Steam ports)
4. Verify Game Files
Corrupt or outdated game files can also trigger connectivity issues. This step is especially helpful for PC players using Steam or other launchers.
To verify files on Steam:
- Go to your Library.
- Right-click on No Man’s Sky and select Properties.
- Navigate to the Local Files tab and click “Verify Integrity of Game Files…”
Missing or corrupted files will be re-acquired and replaced—sometimes that’s all it takes to resolve the error.
5. Disable Firewalls or Antivirus Temporarily
Your system firewall or antivirus could be blocking the game’s access to the Internet. Temporarily disable them to test if NMS connects properly afterward. Remember to re-enable these protections after testing.
Don’t forget to add NMS as an exception to avoid repeated blocking:
- Windows Firewall: Go to Allow an app through firewall and add No Man’s Sky and its launcher.
- Antivirus Software: Access your antivirus settings and add NMS to its exception list.
6. Try a VPN
Sometimes, rerouting your connection through a VPN can stabilize a flaky connection. This can be especially effective if regional server issues are involved.
Make sure the VPN you choose is fast and trustworthy. Here are a few popular ones that gamers use:
- NordVPN
- ExpressVPN
- ProtonVPN
Note: Check NMS’s terms of service when using a VPN, just to be safe.
7. Reinstall the Game (As a Last Resort)
If all else fails, a complete uninstall and reinstall of the game may fix persistent or hidden configuration problems. This is a time-consuming step, but it refreshes all game files and settings.
Make sure to back up your save files if you’re playing offline or using local saves to avoid losing progress.
Bonus: Platform-Specific Tweaks
PC-Specific Fixes:
- Use Steam Big Picture Mode if using a controller to avoid input interference while testing.
- Launch the game as Administrator—this can help with permission-related connection restrictions.
Console-Specific Fixes:
- Clear your console’s cache by holding the power button for 10 seconds and unplugging the power cable for a minute.
- Rebuild your database (for PlayStation): This can be done in Safe Mode and helps with system-level issues affecting connections.
When to Contact Hello Games Support
If you’ve gone through all these steps and still can’t maintain a connection, it might be time to submit a ticket to Hello Games Support. Provide your system details, NAT type, any error message screenshots, and what you’ve tried so far. The more detailed your ticket, the faster they can assist you.
Final Thoughts
While the “You Have Lost Connection” error in No Man’s Sky can be maddening, most causes are relatively simple to fix with basic troubleshooting. Whether it’s a router hiccup, a firewall issue, or just a temporary server glitch, understanding the most common triggers can help get you back to exploring the multiverse in no time.
With games like NMS that rely heavily on both client and server stability, staying proactive can go a long way. Keep your software updated, use a reliable connection, and don’t be afraid to dive into the settings if something seems off.
