There is another error code, Error Code 1017, that is simply another variation of Error Code 721, so if you are encountering Error Code 1017 this guide will apply to you as well. Error Code 721 affects Playstation 4, Xbox One, and PC users alike so there is no system or console immunity to this error code.
Causes of Star Wars Battlefront 2 Error Code 721
There are a number of potential causes for Error Code 721 and not all of them are fixable. For instance, if the root of the error code is DDOS (Distributed Denial of Service) attack on EA then there is nothing that you can except sit and wait until EA software engineers resolve the situation. To know for sure that this is the cause, check with other users to see if they are encountering the same issue.
If they are, then your only solution is to wait. However, if this is not the case, then the cause of this issue is fixable. This error code has been known to be caused by issues such as cached data breaking the online functionality of the game, an unstable default DNS, Universal Plug and Play (UPnP) being enabled, or corrupt installation of the game on your PC. To resolve any of these issues, refer to the associated solution guide in the section below.
How to Fix Star Wars Battlefront 2 Error Code 721
With four distinct, fixable causes of Star Wars Battlefront 2 Error Code 721 comes four unique solutions. Although the unfixable cause, a DDOS attack, is fairly common, there are several other causes that are just as common and might be worth troubleshooting while you are waiting for EA software engineers to fix their servers anyway.
Let us start with the console-related issues and work our way down to PC-related issues, so if you are playing Star Wars Battlefront 2 on a PC I recommend scrolling down to the bottom of this section.
Step 1: Power Cycling Your Console
If you are playing on a Playstation 4 or Xbox One and EA Servers are not experiencing a DDOS attack, it is likely that your issue is stemming from cached data breaking the online functionality of the game. To resolve this issue, you will have to power cycle your console which can be done by performing a hard reset.
To hard reset a PS4, follow these four steps.
On your Dualshock4 controller, press and hold the PS button to bring up the power options menu.
From the list of available power options, select the ‘Turn off PS4’ icon and press the ‘X’ button (make sure you are NOT selecting the ‘Rest mode’ icon).
Once the console completely shuts down, unplug the console’s power cable and wait for at least ten seconds.
Plug the power cable back into your console and turn it back on.
To hard reset, an Xbox One, follow these three steps.
Press and hold the Xbox One power button for at least ten seconds.
When the console is completely shut down, unplug the console’s power cable and wait for at least ten seconds.
Once ten seconds have elapsed, plug the power cable back into your console and turn it back on.
2. Disabling UPnP
While Universal Plug and Play (UPnP) is a feature meant to stabilize online multiplayer connection, the feature has an adverse effect on Star Wars Battlefront 2. There have been many reports of people resolving Error Code 721, or 1017, by disabling UPnP. If you believe this might be your issue, to disable UPnP follow these five steps.
Make sure that your computer/console is connected to your router or modem.
Open your default browser and type in one of the following addresses (192.168.0.1 or 192.168.1.1) and press ‘Enter’.
Insert your credentials at the login page. (Many manufacturers use default usernames and passwords like “admin” or “1234”)
Once you gain access to your router settings, open ‘Advanced (Expert)’ settings and look for a ‘Nat Forwarding’ sub-tab. Access is and makes sure that UPnP is enabled.
Adjust the toggle next to UPnP to disable it, then restart your router.
3. Change Default DNS to Google DNS
A possible solution for console and PC users is to change your default DNS addresses to Google’s DNS addresses. However, there is a different method of doing this for PS4, Xbox One, and PC users alike so we will go over each method in an individual guide.
For PS4 users, follow these five steps.
From your dashboard, go to ‘Settings’ then ‘Network’ then ‘Set up Internet Connection’.
Choose Wi-Fi or LAN depending on which one you are using.
Choose ‘Custom’, then set the IP address to ‘Automatic’.
Set the ‘DHCP Host Name’ to ‘Do Not Specify’.
Then, set the ‘DNS Settings’ to ‘Manual’, set the ‘Primary DNS’ to ‘126.96.36.199’, and set the ‘Secondary DNS’ to ‘188.8.131.52’.
For Xbox One users, follow these three steps.
From the Xbox One menu, go to ‘Settings’ then ‘Network’ then ‘Advanced Settings’.
Choose ‘DNS Settings’ and select ‘Manual’.
Then, enter ‘184.108.40.206’ for the ‘Primary DNS’ and ‘220.127.116.11’ for the ‘Secondary DNS’.
For PC users, follow these six steps.
Press ‘Windows’ + ‘R’ to open up a Run dialog box. Type ‘ncpa.cpl’ into the text box and press ‘Enter’ to open up the ‘Network Connections’ window.
Select the connection that you want to configure the Google Public DNS.
Inside the ‘Wi-Fi/Ethernet Properties’ screen, go to the ‘Networking’ tab and go to the settings box under ‘This connection uses the following items’. Select ‘Internet Protocol Version 4’ and click the ‘Properties’ icon.
Go to the ‘General’ tab, select the toggle associated with ‘Use the following DNS server address’ and replace the ‘Preferred DNS Server’ with ‘18.104.22.168’ and the ‘Alternate DNS Server’ with ‘22.214.171.124’.
Repeat steps 3 and 4 with ‘Internet Protocol Version 6’, but use ‘2001:4860:4860:8888’ for ‘Preferred DNS Server’ and ‘2001:4860:4860:8844’ for ‘Alternate DNS Server’.
Restart your network connection.
4. Reinstall Star Wars Battlefront 2 (PC Only)
Some people have reported success in resolving the issue after reinstalling the game due to a faulty installation the first time. To reinstall Star Wars Battlefront 2 on your PC, follow these three steps.
‘Windows’ + ‘R’ to open up Run dialog box. Type ‘appwiz.cpl’ and press ‘Enter’ to open up the Programs and Features window.
Right-click on Star Wars Battlefront 2 and choose ‘uninstall’.
Re-download the game from Origins or Steam.
Hopefully one of the troubleshooting methods listed above comes in handy the next time you run into this error code. Unfortunately, if the issue at hand is a DDOS attack, there is no method we can offer other than sitting and waiting and maybe angry tweeting at EA customer support.
