Why does error 264 happen on one device?

Error 264 can appear on a single device if you have multiple browser tabs open with Roblox, or if a previous game session did not close properly. The Roblox session from your last game may still be registered as active on the servers.

Can someone else trigger error 264 on my account?

Yes. If someone else is using your Roblox account on another device at the same time you will both get error 264. If this is happening without your knowledge change your password immediately and enable 2-step verification.

How is error 264 different from error 273?

They are very similar. Error 264 specifically refers to the same account being launched in a new game session while already active. Error 273 more broadly indicates the account is being used on another device. In practice the fixes are identical.

Will signing out of all sessions fix error 264?

Yes. Go to roblox.com, click Settings, then Security, then Sign out of all other sessions. This terminates every active session on your account. Wait 30 seconds then try launching Roblox again.
