If you are trying to figure out how to fix roblox error code 264 same account because you just got booted from a game, you are definitely not alone. It usually happens right when you're in the middle of something important, and suddenly a grey box pops up telling you that you've been disconnected. The message basically says "Same account launched game from different device," which is pretty self-explanatory, but that doesn't make it any less annoying when you know for a fact you aren't playing on two screens at once.
Most of the time, this is just a little glitch where Roblox thinks a previous session is still active. Maybe you left the game open on your phone, or perhaps your PC didn't tell the servers you actually quit five minutes ago. Whatever the reason, we can get it sorted out pretty quickly so you can get back to your games without the constant interruptions.
What exactly is Error 264?
Before we jump into the fixes, it helps to understand what the servers are thinking. Error 264 triggers when the Roblox servers detect that your specific account is trying to join a game while another session is already live. Roblox doesn't allow one account to be in two places at the same time—it's a security thing and a way to prevent people from farming stats or items unfairly.
The problem is that the "session" doesn't always close instantly. If your internet flickered or if you just slammed your laptop shut, the server might still think you're standing there in the game world. When you try to log back in from another device (or even the same one), the server sees a duplicate and shuts the new connection down.
The fastest way to fix the "Same Account" error
The most common way to fix this is the simplest: just log out of everything. If you have Roblox on your phone, your iPad, and your computer, there is a high chance one of them is "ghosting" your account.
Go to your Roblox settings on a browser. Head over to the Security tab. If you scroll all the way to the bottom, you'll see an option that says "Sign Out of All Other Sessions." Click that. It's like a giant reset button for your account's presence online. Once you do that, wait about thirty seconds, then try logging back into the device you actually want to play on. This usually clears the error 90% of the time because it forces the servers to realize you aren't actually active anywhere else.
Clearing your Roblox cache data
Sometimes the issue isn't on the server's end; it's stuck in the temporary files on your computer. Your PC stores little bits of data to help the game load faster, but if that data gets corrupted or stuck, it can keep sending the wrong "status" to Roblox.
To clear this out, you'll want to perform a bit of "digital spring cleaning." Press the Windows Key + R on your keyboard to open the Run box. Type in %localappdata% and hit enter. This opens up a folder filled with app data. Look for the folder named "Roblox." Don't worry, deleting this stuff won't delete your account or your progress; it just clears out the temporary cache.
Once you're in the Roblox folder, highlight everything and delete it. After that, empty your recycle bin for good measure. When you launch Roblox again, it will take a second longer to load because it has to fetch fresh data, but this often clears that persistent 264 error that refuses to go away.
Check your mobile devices
We've all done it—you're playing a quick game on your phone while waiting for something, then you just lock your phone and put it in your pocket. The thing is, many mobile devices keep apps running in the background to make it easier to jump back in. Roblox might still be "heartbeating" to the server from your pocket.
If you're getting the 264 error on your PC, grab your phone or tablet. Don't just close the app; actually go into the app switcher and swipe Roblox away so it's completely shut down. It sounds almost too simple to work, but background processes are a huge culprit for this specific error code.
Dealing with browser cookies and site data
If you play Roblox through a web browser rather than the standalone desktop app, your browser might be holding onto some old login "tokens." These tokens tell the website who you are, but if they get tangled up, they can cause the "same account" conflict.
Try logging out of the Roblox website entirely. After that, clear your browser's cookies and cache. In Chrome, you can do this by hitting Ctrl + Shift + Delete. Choose to clear "Cookies and other site data." Once that's done, log back in. It's a bit of a hassle to type your password again, but it ensures your browser is sending a fresh, clean request to the Roblox servers.
Is someone else using your account?
This is the part nobody wants to talk about, but it's a possibility. If you've tried logging out, clearing your cache, and checking your phone, and the error still pops up immediately after you join a game, someone else might have your login info.
If a "hacker" or even just a friend you shared your password with logs into your account while you're playing, you'll get kicked with Error 264. If you suspect this is the case, change your password immediately.
While you're at it, make sure you have Two-Factor Authentication (2FA) turned on. It's a lifesaver. Even if someone gets your password, they won't be able to log in without the code sent to your email or an authenticator app. This stops the "same account" conflict from happening because someone else is trying to sneak onto your profile.
The "Wait and See" approach
I know, waiting is the worst. But sometimes the Roblox servers are just having a bad day. If there's a massive update or if the servers are under a lot of stress, the communication between your game and the main database can lag.
If you've tried the fixes and nothing is working, give it fifteen minutes. Go grab a snack, walk around, and let the server-side session "time out" on its own. Often, the system just needs a moment to realize the other device isn't actually there anymore.
Using the Roblox App vs. The Website
Lately, Roblox has been pushing players toward their Windows App rather than launching through the website. Sometimes, having both the website open in Chrome and the Roblox App running can cause a weird feedback loop where the app thinks the website is a separate session.
If you're using the app, try closing your browser entirely before you hit play. Conversely, if you're a die-hard browser user, make sure the background Roblox process isn't running in your Task Manager. Hit Ctrl + Shift + Esc to check. If you see "Roblox" or "Roblox Game Client" in the list, end the task and try again.
A quick summary of the fix list
To keep things easy, here is the shorthand version of what you should do if this keeps happening: 1. Log out of all other sessions in your account security settings. 2. Force-close the app on your phone or tablet. 3. Clear the %localappdata% Roblox folder on your PC. 4. Refresh your browser or clear your cookies. 5. Change your password if you think your account isn't secure.
Dealing with how to fix roblox error code 264 same account isn't usually a sign of a broken computer or a dead account—it's just a digital hiccup. Most players find that the "Sign Out of All Sessions" trick is the silver bullet that fixes it instantly. Just remember to keep your account details private and give the servers a second to breathe if things get glitchy. You'll be back to your favorite hobby in no time.
