Don't worry if you've encountered error 264 in Roblox, with the message "Same account launched game from different device." Fixing your issue is usually as easy as logging out of Roblox on all your devices. But if that doesn't work, there are other simple fixes you can try as well.

What Causes Error 264 on Roblox?

The most common reason you see error 264 in Roblox is that you've logged in to your Roblox account on multiple devices, so the app thinks you're trying to launch the same item on multiple devices.

There are other potential causes of this error as well, though, including a faulty Roblox app cache, an unstable internet connection, and more. We'll show you how to fix all of them.

How to Resolve Error 264 on Roblox

Fixing error 264 in Roblox isn't as difficult as you might think, as you can usually fix it by logging out of your account. If that doesn't work, though, we've given instructions for other potential fixes as well. Be sure to test Roblox works again after each section below—that way you can stop troubleshooting as soon as you've fixed it.

Log Out of Your Roblox Account on Your Other Devices

If you're logged in to your Roblox account on multiple devices, sign yourself out of those devices and see if that resolves your issue. This ensures the app doesn't detect multiple logins, which prevents you using it.

Signing out of Roblox on your devices is as easy as dipping into the settings. For example, if you're using Roblox on a Windows PC, you can log yourself out by clicking the three dots in the left sidebar and choosing "Log Out" on the following page.

If you don't have access to the device where you're logged in to your Roblox account, use the platform's official website to remotely log out of your account on all your devices.

To do that, launch a web browser on your current device, open Roblox.com, sign in to your account if you haven't already, select the gear icon in the top-right corner, and choose Settings > Security.

Here, in the "Where You're Logged In" section, you'll see the devices where you're logged in to your Roblox account. To log out from a specific device, select that device on the list and choose "Log Out of Session."

To sign out of your Roblox account on all your devices at once (except for the website where you're currently logged in), choose "Log Out of All Other Sessions." And that's it.

This probably fixed Roblox for you, but if error 264 pops up again, try out the extra fixes below.

Clear the Roblox Cache on Your Computer

If you're still getting the same error, your Roblox cache files may be corrupted. These files may still be thinking you're logged in on multiple devices, leading to the problem.

You can fix that by clearing your Roblox app's cache. Doing so won't delete your account data, and Roblox will rebuild this cache as you use the app.

To clear the cache on your Windows 11 or Windows 10 PC, open the Run Dialog box by pressing Windows+R, type the following path in the box, and press Enter:

%temp%\Roblox

In the open folder, select all files by pressing Ctrl+A. Right-click a selected file and choose "Delete" (a trash can icon). This will clear Roblox's cache.

If you're a Mac user, then open Finder, select Go > Go to Folder from the menu bar, enter the following in the open box, and press Enter:

~/Library/Caches

Access the folder named "com.roblox.com," select all files in the folder by pressing Command+A, Control-click a selected file, and choose "Move to Trash."

Restart Your Router

If your internet connection isn't working, that may be why you're having problems with Roblox. In this case, give your router a reboot to possibly fix your issue.

How you restart your router depends on the particular router model. Some routers have a Power button that you can use to turn the device off and back on. For other routers, you can unplug the device from the power socket and plug it back in.

When you've rebooted your router, your computer will reconnect to the internet and you can try Roblox again.

Flush Your DNS Cache

Your computer's DNS cache helps internet-enabled apps like Roblox translate domain names to IP addresses. If this cache is corrupted, that may be why you're having trouble using Roblox.

In this case, you can clear your computer's DNS cache to resolve your issue. Your machine will rebuild the cache as you browse various websites.

To clear the DNS cache on a Windows 11 or 10 PC, open the Start Menu, find "Command Prompt", and launch the tool. Then, type the following prompt in the CMD window and press Enter:

ipconfig /flushdns

If you're a Mac user, open a Terminal window and run the following command to clear macOS's DNS cache:

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

Update Roblox on Your Computer

If your Roblox app is outdated, that may be the reason you're getting an error 264 popup. Old app versions often have bugs, which create various random problems. Luckily, you can fix those bugs and other app issues by simply updating your app to the latest version.

Updating Roblox on a Windows PC or Mac is as easy as quitting and re-opening the app. When you relaunch Roblox, it looks for available updates, installs them, and then launches fully.

If you've downloaded Roblox from the Microsoft Store on your Windows PC, update your app by visiting Microsoft Store > Library and selecting "Update" next to Roblox.

And that's how you deal with an error 264 in Roblox on your Windows or Mac computer. Happy gaming!
