Common Causes

   • Blocked ports required by the game.
   • Incorrect Universal Plug and Play (UPnP) or NAT settings.

Top Fixes for Error Code 770

1. Check EA Server Status

Start by ensuring that EA’s servers are operational. Visit EA’s official server status page to confirm whether the issue is on their end. If there is scheduled maintenance or unexpected downtime, you may need to wait.

2. Restart Your Network Devices

Unplug your router and modem for at least 5 minutes. This allows your network devices to reset and clear potential connection issues. Once done, reconnect your console or PC and attempt to play the game again.

3. Switch to a Wired Connection

Wireless connections can be unstable, especially during online gaming. If possible, use an Ethernet cable to connect your console or PC directly to the router for a stronger and more consistent connection.

4. Configure Port Forwarding

Some ports need to be open for Battlefront 2 to connect to EA’s servers. Log into your router’s admin panel and forward the following ports:

• PC:
  • TCP: 80, 443, 3478-3480
  • UDP: 3659, 3478-3479
• Xbox:
  • TCP: 3074
  • UDP: 88, 500, 3074, 3544, 4500
• PS4:
  • TCP: 3478-3480
  • UDP: 3074

Save the settings, restart your router, and try connecting to the game again.

5. Enable DMZ (Demilitarized Zone)

DMZ removes restrictions on your device’s connection, ensuring all ports are open. This is particularly helpful for consoles. To enable DMZ:

1. Access your router’s settings.
2. Locate the DMZ option and enable it.
3. Enter your console’s IP address.
4. Save the settings and restart your router.

Note: DMZ can expose your device to potential security risks, especially on PC, so proceed with caution.

6. Whitelist Battlefront 2 and Origin in Your Firewall

On PC, ensure that your firewall isn’t blocking Battlefront 2 or Origin. To check:

1. Open the Windows Start menu and type “firewall.”
2. Select Allow an app through Windows Firewall.
3. Ensure that both Battlefront 2 and Origin are on the allowed list for public and private networks.
4. If they aren’t listed, click Allow another app and add them manually.

7. Assign a Static IP Address

Using a static IP address ensures a more stable connection. Here’s how to set it up on Windows:

1. Open Settings and navigate to Network & Internet.
2. Click Wi-Fi or Ethernet, depending on your connection.
3. Select Edit IP settings and toggle Manual.
4. Enable IPv4 and enter your IP address and preferred DNS.

8. Clear Game Cache and Save Data

Corrupt game files can also cause connectivity issues. On consoles, clear the save data for Battlefront 2 (it will sync from the cloud when you log in). On PC, follow these steps to clear the cache:

• Restart your PC and launch Origin to test the game.
• Close Origin completely.
• Press Windows + R to open the Run dialog box.
• Type %ProgramData%\Origin and press Enter.

• In the folder that opens, delete all files and folders except for LocalContent (do not delete this folder).
• Press Windows + R again, type %AppData% and press Enter.
• Delete the Origin folder.
• In the address bar, click AppData to go back one step, then open the Local folder.
• Delete the Origin folder located there.

9. Test with an Alternate Network

If possible, connect your PC or console to a different network (such as a mobile hotspot). This can help identify whether the issue lies with your ISP or router.

10. Reinstall the Game or Update Drivers

If none of the above works, reinstall Battlefront 2 to replace any corrupted files. Additionally, ensure your network and graphics drivers are up to date.

Why Does Error Code 770 Occur?

Error 770 often arises due to conflicts in your network setup or blocked connections between your device and EA’s servers. In some cases, it may simply be an EA server outage. However, by following the steps above, you can identify and resolve most of these issues.
