If you're trying to figure out how to fix roblox error code 264, you've likely just been kicked out of a game with that frustrating message saying "Same account launched from different device." It's one of those bugs that pops up at the worst possible time—usually right when you're about to win a match or finally finish a difficult obby. The good news is that while it looks like a serious technical glitch, it's actually one of the easier problems to solve once you understand why Roblox is throwing a tantrum.
Essentially, this error happens because the Roblox servers think you're trying to play from two places at once. Roblox doesn't allow a single account to be active in two different game sessions simultaneously. Sometimes it's a genuine mistake—maybe you left the app open on your phone while trying to play on your PC—but other times, it's just a "ghost" session where the server hasn't realized you've already logged off.
What Actually Causes Error Code 264?
Before we dive into the nitty-gritty fixes, let's talk about why this keeps happening. The most common culprit is simply multi-device usage. If you were playing on your iPad earlier and then hopped onto your laptop without properly closing the app on the tablet, the server might still think you're "in-game" on the first device.
However, it's not always your fault. Sometimes, Roblox's servers are just a bit slow to update. You might have closed the game perfectly fine, but the server is lagging behind and still registers your account as active. There's also the slightly more stressful possibility that someone else has access to your account, but let's not jump to conclusions just yet. Most of the time, it's just a cache issue or a lingering session that needs to be cleared out.
The Quickest Fix: Log Out of All Sessions
The absolute fastest way to handle this is to force Roblox to realize you aren't playing anywhere else. You don't even need to be at the computer where the "other" session might be running. You can do this from any browser.
- Open your web browser and head over to the official Roblox website.
- Log into your account if you haven't already.
- Click on the Gear icon in the top-right corner and select Settings.
- On the left-hand sidebar, click on the Security tab.
- Scroll all the way to the bottom until you see a button that says "Log Out of All Other Sessions."
Give that button a click. It's like a giant reset switch. It tells Roblox to instantly disconnect every single instance of your account everywhere in the world—except for the browser window you're currently using. After you do this, wait about 30 seconds, then try launching your game again. Nine times out of ten, this clears up error code 264 instantly.
Clearing the Roblox Cache on Your PC
If logging out didn't do the trick, the problem might be living locally on your computer. Your PC stores temporary files (cache) to help Roblox run faster, but sometimes these files get corrupted or stuck. When that happens, the app gets confused and thinks a session is still active when it isn't.
To clear the cache, you'll need to do a little bit of "folder hunting," but it's nothing too scary.
First, make sure the Roblox app is completely closed. Then, press the Windows Key + R on your keyboard to open the Run box. Type in %localappdata% and hit Enter. This will open up a big folder full of app data. Look for the folder named Roblox.
Inside that Roblox folder, you're going to see a few things, but we're looking for the Downloads folder and the Version folder. Honestly, the safest bet is to just delete the contents of the "Logs" folder and "LocalStorage." Don't worry, you aren't deleting your games or your Robux; you're just clearing the "short-term memory" of the app. Once you've emptied those out, restart your computer and try logging back in. It's like giving the app a fresh cup of coffee—it usually wakes up and behaves.
Dealing with the Error on Mobile
If you're a mobile player and you're seeing this error, the process is a little different but still pretty straightforward. Sometimes the app on your iPhone or Android device gets hung up on an old session.
The first thing to try is the classic "Force Stop." On Android, go to your settings, find your apps, tap on Roblox, and hit Force Stop. Then, clear the cache in the storage settings of the app. On iOS, you just need to swipe up and kill the app from your multitasking view.
If that doesn't work, I'd recommend a quick reinstall. It sounds like a hassle, but mobile apps are notorious for holding onto "zombie" data that causes error code 264. Delete the app, restart your phone (seriously, don't skip the restart!), and then download it fresh from the App Store or Play Store.
When You Should Worry About Your Account Security
I don't want to freak you out, but we have to mention the "elephant in the room." If you are 100% sure you haven't logged in on another device, and you've cleared your cache, and you've logged out of all sessions, but the error still keeps popping up it might mean someone else is trying to get into your account.
If you suspect this, don't panic. Just be proactive. Go back into your Security Settings and change your password immediately. Make sure it's something you haven't used before. While you're in there, enable Two-Factor Authentication (2FA). Using an authenticator app or even just email verification makes it way harder for anyone else to trigger error code 264 on your account because they won't be able to get past the login screen.
Once you change your password and hit that "Log Out of All Other Sessions" button again, any unwanted guests will be booted out for good, and you'll have your account back to yourself.
Why Browser Cookies Matter
Believe it or not, your web browser might be the one causing the drama. If you play Roblox through the browser (by clicking play on the website which then launches the app), your browser cookies might be storing old login data that's conflicting with the app.
Try clearing your browser cookies and site data. In Chrome or Edge, you can usually do this by hitting Ctrl + Shift + Delete. Just make sure you select "Cookies and other site data" for "All time." After you clear them, you'll have to log back into the Roblox site, but this often fixes those weird synchronization issues that lead to the 264 error.
A Note on "Ghost" Servers
Sometimes, the issue isn't on your end at all. Roblox servers occasionally go through "hiccups." If a server you were playing on crashes, it might not report back to the main system that you've left. This creates a "ghost" of your character that stays stuck in that crashed server.
If this is the case, no amount of cache clearing will fix it immediately. You just have to wait. Usually, these ghost sessions time out on their own within 10 to 15 minutes. If you've tried everything and it's still not working, go grab a snack, watch a YouTube video, and come back in 20 minutes. Time is a great healer for server-side bugs.
Wrapping Things Up
Knowing how to fix roblox error code 264 really comes down to a few simple steps: logging out of other devices, clearing your temporary files, and making sure your account is secure. It's a pesky interruption, sure, but it's rarely a permanent problem.
Most of the time, that "Log Out of All Other Sessions" button is your best friend. It's the "turn it off and back on again" solution of the Roblox world. Just remember to keep your 2FA turned on so you don't have to worry about anyone else causing this error for you. Now that you've got the fixes under your belt, you can get back into the game and stop worrying about being kicked out by your own "ghost!"
