You’re sitting there, lightsaber ready, heart set on a massive game of Galactic Assault, and then it hits you. That gray box. The dreaded Star Wars Battlefront 2 error code 721. It’s annoying. Honestly, it’s one of the most frustrating parts of being a Battlefront fan because it usually happens exactly when you have an hour of free time to actually play.
Essentially, error 721 is a connection failure. It means your game client can’t shake hands with the EA servers. While it looks like a total "game over" screen, it’s usually just a temporary hiccup in the digital pipeline. Sometimes it's EA's fault. Sometimes it's your router acting like a grumpy protocol droid.

Let's break down what’s actually happening under the hood.
What causes the Battlefront 2 error code 721 anyway?
Most players assume the game is broken. It’s not. Most of the time, the Battlefront 2 error code 721 pops up because of a handshake timeout. Think of it like a crowded doorway. If too many people try to shove through at once, or if the guy holding the door open drops the handle, nobody gets into the party.
EA’s servers for Battlefront 2 aren't exactly brand new anymore. Since the game transitioned to a "legacy" state with no more major content updates, the server infrastructure occasionally gets moved around or downsized. This leads to instability. You might also see this error if your ISP is throttling your connection or if your DNS settings are routing your traffic through a scenic—but very slow—pathway across the country.
The Role of the EA Account
Sometimes, the issue isn't even the connection. It’s your account. If your EA account password has expired or if you haven't logged into the EA App (formerly Origin) in a while, the game might throw a 721 error instead of just telling you to update your credentials. It’s a bit of a lazy error message, to be honest. It just groups all "failed to connect" instances into one bucket.
First steps to fix the connection
Don't go reinstalling the game yet. That’s a 90GB headache you don’t need.
First, try the "Spam Connect" method. It sounds stupid. It feels like it shouldn't work. But in the Battlefront community, it’s a legendary fix. When you get the 721 error in the main menu, just keep clicking "Connect." Sometimes it takes three tries. Sometimes it takes ten. Often, the server just needs a second nudge to recognize your request.
If that fails, check the server status. Use a site like DownDetector or follow the EA Help Twitter account. If the servers are down for maintenance, no amount of troubleshooting on your end will do anything. You just have to wait it out and maybe go watch The Empire Strikes Back while the engineers do their thing.
Refreshing your local network
Still stuck?
Go to your router. Pull the plug. Count to thirty. It’s a cliché for a reason—it clears the cache and forces a new IP assignment. While your router is rebooting, do a hard restart on your PC or console. This clears out the temporary files that might be gumming up the works.
Changing your DNS settings for a more stable link
If the basic stuff isn't working, it’s time to look at your DNS. Most people use whatever DNS their internet provider gives them. Those are usually slow and prone to timing out during peak gaming hours. Switching to a public DNS like Google’s or Cloudflare’s can drastically reduce the occurrence of Battlefront 2 error code 721.
On a PC or PS5/Xbox, you can manually set your DNS. For Google, use 8.8.8.8 as your primary and 8.8.4.4 as your secondary. For Cloudflare, it’s 1.1.1.1.
I’ve seen this fix the issue for dozens of players who were about to give up on the game. It streamlines the "lookup" process the game uses to find the EA servers. It’s basically like giving your computer a better map to the data center.
Dealing with the EA App and Cache issues
If you are on PC, the EA App is often the culprit. It’s notoriously buggy.
The app stores "App Recovery" data that can become corrupted. If that data is bad, the Battlefront 2 error code 721 will persist no matter how good your internet is.

- Open the EA App.
- Click the three dashes in the top left corner.
- Go to Help.
- Click App Recovery.
- Select Clear Cache.
This will restart the app and force it to re-verify your login status. This is a common fix for players who find they can play other online games but specifically get blocked by Battlefront 2.
UPnP and Port Forwarding
If you’re still seeing the error, your router’s firewall might be blocking the specific ports Battlefront 2 needs. You want to make sure UPnP (Universal Plug and Play) is enabled in your router settings.
If you want to be more precise, you can forward these specific ports for Battlefront 2:
- TCP: 80, 443, 9988, 17502, 20000-20100, 22990, 42127
- UDP: 3659, 14000-14016, 22990, 25200-25300
It sounds technical, but most modern router interfaces make this pretty straightforward.
Why the error persists for some players
Sometimes, the error is regional.
EA uses various data centers globally. If the Virginia server is having a meltdown, players on the US East Coast will see the Battlefront 2 error code 721 while someone in California is playing just fine.
You can actually try to change your "Ping Site" in the game settings under Options > Account. However, if you can't even get past the main menu to see the settings, this isn't helpful. If you can get into the menu but keep getting booted, try switching your ping site to a different region, even if the latency is a bit higher. Sometimes a stable connection to a distant server is better than a broken connection to a nearby one.
Consoles vs. PC
On PlayStation and Xbox, the 721 error is frequently tied to the console’s "Rest Mode." If you leave the game running and put the console to sleep, the connection to EA's servers times out. When you wake the console up, the game tries to resume a session that the server has already closed.
The solution here? Always "Quit" the game completely before turning off your console. Don't rely on Quick Resume or Rest Mode for multiplayer titles. It breaks the handshake almost every single time.
Summary of actionable steps
If you are currently staring at that error screen, here is your checklist to get back into the fight:

- The "Spam" Fix: Hit the "Connect" button repeatedly (up to 10 times). It actually works more often than you'd think.
- Account Refresh: Log out of the EA App or your console profile and log back in to refresh your credentials.
- Clear Cache: Use the EA App Recovery tool or hard-reboot your console to wipe temporary connection data.
- DNS Swap: Change your network settings to use Google (8.8.8.8) or Cloudflare (1.1.1.1) DNS.
- Router Cycle: Unplug your router for 30 seconds to force a fresh connection to your ISP.
- Check Server Status: Verify that the EA servers aren't actually down for maintenance before you spend an hour troubleshooting your own gear.
Dealing with the Battlefront 2 error code 721 is a rite of passage for many players these days. Since the game isn't receiving active patches, the community has become the primary source for these workarounds. Usually, it's just a matter of persistence and clearing out old data. Once you've cleared the cache and refreshed your DNS, you should be back to defending theed or taking down Walkers in no time.
Check your EA account email as well. Rarely, EA might have flagged your account for a security reset, and you won't be able to connect until you've followed the link in their email to verify your identity. It’s a small detail, but it’s caught many veteran players off guard.
