How to Fix Error Code 721 in Battlefront 2

1. Check EA Server Status

Before troubleshooting, verify if EA’s servers are down:

• Power cycle your router: Unplug it for 30 seconds, then reconnect.
• Restart your PC/console to refresh the connection.

3. Update the Game & Platform

On PC (Steam/Origin/Epic Games):

• Verify game files (Steam: Right-click game > Properties > Local Files > Verify Integrity).
• Update the game and launcher.

On Console (PS/Xbox):

• Check for game updates in the store.
• Ensure PlayStation Network or Xbox Live is operational.

4. Change DNS Settings (PC & Console)

Switch to Google DNS to improve connection reliability.

On PC:

1. Go to Network and Sharing Center → Change adapter settings
2. Right-click your active connection → Properties

7. Run the Game as Administrator (PC)

8. Keep Retrying the Connection

Some players report success by:

9. Verify Game Files (PC – Steam/Origin)

Corrupted files can trigger server connection issues.

Final Thoughts

Error Code 721 is usually temporary and caused by server issues or network misconfigurations. If EA’s servers are up but the problem persists, try changing DNS, disabling UPnP, or verifying game files. If all else fails, wait for an official fix from EA.
