Roblox 264 on PC: same account joined from another device
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Roblox shows 264 when the same account tries to join the same game from several devices at once. Close Roblox on the phone, tablet, console or other PC where your session is open and join again from a single device.
Safety first
Stop and check this first
- If none of your devices has Roblox open and 264 keeps appearing, treat it as possible access to your account by someone else and contact Roblox Support from its official website.
- No one from Roblox will ask for your password or verification codes by chat or message: do not install "fixers" or share your account to solve an error code.
Safe checks you can perform
- Other devices with Roblox open
- Clean Roblox reinstall on Windows
- Another internet connection

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

They must show youthe reply to your request with its number.
In writingthe case number, the device and operating system and the checks already ruled out.
Line check by your internet provider

They must show youthe result of their line test.
In writingthe incident number and what was changed.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

- you.
- How:
- check the phone, tablet, console and any other PC where you use your account and close Roblox fully on all of them. Wait a moment and join the game from a single device.

- If you get in:
- another session of the same account was in the same game.
- If it appears anyway with no other session open:
- continue with the reinstall.
- Evidence to keep:
- the list of devices checked and which one had Roblox open.

What it means
Roblox explains that error code 264 occurs when the same account attempts to access the same game from multiple devices simultaneously. It is a check on the account session on Roblox's servers, not a PC fault. If no other session is open, Roblox gives the general steps of its guide: reinstall the app and clear its data on Windows, try another connection and, if it persists, talk to your internet provider. The code does not say which other device holds the session.
