The action-adventure game Sea of Thieves provides interesting sailing mechanics but it also has a lot of critics for its issues. The connection problem is one of these issues.

It’s very vexing when your internet connection is working perfectly and nothing wrong with your bandwidth and net speed but the game told you “Connection to server has been lost. Please check your connection and try again.” Feel frustrating huh? Don’t worry, you’re not alone.

Try these fixes:

There’re 5 fixes that have been proved useful by other users. You don’t have to try them all; just work your way down the list until you find the one that works for you.

  1. Update your network adapter driver
  2. Change the proxy settings
  3. Use Netsh.exe tool
  4. Allow Sea of Thieves run in the background
  5. Disable your firewall

Fix 1: Update your network adapter driver

One common reason for the connection issue is that your network adapter driver is out of date or wrong. Windows 10 doesn’t always give you the latest version. But with outdated or wrong drivers, you may encounter the connection issue or other problems. So it’s really important to keep your drivers updated to receive better user experience.

There are two ways you can update your driver: manually and automatically.

Option 1 – Manually– You’ll need some computer skills and patience to update your drivers this way, because you need to find exactly the right the driver online, download it and install it step by step.


Option 2 – Automatically (Recommended)– This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.

Option 1 – Download and install the driver manually 

You can download network adapter drivers from the manufacturer official website. Search for the model you have and find the correct driver that suits your specific operating system. Then download the driver manually.

Option 2 – Automatically update drivers

If you don’t have time or patience to manually update your network adapter drivers, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click the Update button next to the flagged driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version). 
    Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)   
  4. Relaunch the game and check whether it will freeze or not.

Fix 2: Change the proxy settings

  1. Press the Windows logo key + R together to open Run box.
  2. Type inetcpl.cpl and click OK.
  3. Click the Connection tab.
  4. Click LAN settings.
  5. Untick everything except Automatically detect settings.
  6. Reboot Sea of Thieves.

Fix 3: Use Netsh.exe tool

One possible fix for the connection issue is using the Netsh.exe tool to remove the old proxy server and configure direct access to the internet.

  1. Press the Windows logo key + R together to open Run box.
  2. Type cmd and click OK.
  3. Type netsh winhttp reset proxy and press the Enter key.
  4. Launch the game to check.

Fix 4: Allow Sea of Thieves run in the background

Check your Windows permission, if the app was not allowed running in background entirely, that’s the cause of your game deny internet access when you alt-tabbed.

  1. Press the Windows key + I together.
  2. Click Privacy.
  3. In the left pane, click Background apps.
  4. Make sure the button beside Sea of Thieve is on.
  5. Restart the game.

Fix 5: Disable your firewall

If the above fixes don’t help, you could give this fix a try. The presumption is that your firewall may block some features from Sea of Thieves so the problem appears.

Disable your firewall and launch the game. If it works fine, you can try to re-enable your firewall.

NOTE: Please be careful searching or downloading stuffs from internet when your firewall was disabled.
