The STAR WARS Battlefront II is a game that has a strong player base. But fans are hit with some server connection issues, along with different error codes such as the error code 721, which can’t let you play online and connect. If you have no clue what’s going on, follow the instructions in this article to troubleshoot the issues and you should be able to go online.

Before getting started

Before jumping into complicated fixes, you can isolate the issue by checking if it’s on the game’s end. It could be possible that the servers are down and it’s under maintenance.

Different EA games run on different servers. Basically, you can check the games’ server status by visiting the EA Help page and choose your game from the list. From your game’s page, there’s a Server Status icon. But for STAR WARS Battlefront II, there is no such an icon. Instead, you can check @EAHelp on Twitter to find out what’s happening, and to get real-time updates.

If there are no reports on the server side, try these fixes:

  1. Restart your router
  2. Update your network adapter driver
  3. Flush your DNS cache
  4. Switch to a different DNS
  5. Use a wired connection

Fix 1: Restart your router

Sometimes your internet connection can drop out. If that happens, restarting your router can make it reconnect faster.

Turn your router off and then unplug it. Wait about a minute then plug it back in, turn it back on, and try connecting again.

Fix 2: Update your network adapter driver

This issue is related to network or server connectivity. So your outdated network adapter driver can be the culprit and make your game unplayable. To fix it, you’re supposed to update your network adapter driver, especially if you can’t remember when was the last time you updated it.

You can manually update your network adapter driver by going to the manufacturer’s official website to download and install the correct network driver for your system.


You can do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct driver for it.

Fix 3: Flush your DNS cache

Not being able to connect to the servers may indicate there’s something wrong with the internet connectivity. To troubleshoot it, you need to clear the DNS cache. Here are the steps you can follow:

1) Press the Windows logo key to open the Start menu. Type cmd. Right-click Command Prompt from the results and select Run as administrator.

2) In the Command Prompt window that appears, type the following command and then press Enter.

ipconfig /flushdns

If successful, the Command Prompt will report back with “Successfully flushed the DNS Resolver Cache.”

Once done, restart your computer and try to launch your game to check if it works.

Fix 4: Switch to a different DNS

Your Internet Service Provider (ISP) translates internet addresses from a human-readable address (like to a computer-readable one (a string of numbers) using a sort of reverse phone-book known as a Domain Name System.

If something goes wrong with the DNS you are using, you can have a terrible time trying to connect to the internet. Switching to a different DNS is a techie trick that can help you. Here we recommend Google DNS, which is one of the free options that are available.

1) In the bottom right corner of your desktop, right-click on the network icon and select Open Network & Internet settings.

Then click OK to save the changes.

After you’ve applied the changes, launch your game and the server connectivity issue should be fixed.

Fix 5: Use a wired connection

If you’re using Wi-Fi or wireless connection on your PC, it’s time for you to see if a wired connection will improve the situation. To do that, use a LAN cable to connect your device to the router and restart the game to check if it resolves your issue.
