An error is a piece of information displayed when an unexpected event occurs. It can range from a broken game feature to Roblox shutting down entirely. Error messages are seen widely throughout Roblox and are part of every Roblox platform.
On the game client, if an error has occurred, the error message will appear in the center of the screen in the form of a gray dialog box, which will tell the user what the error is and gives the option to leave or reconnect when applicable. On mobile, the gray error dialog box can be small. There was a bug on mobile where you couldn't see the gray error dialog box whatsoever. In the case of non-in-game errors, the error message will appear in the form of a separate page, typically with a Roblox-themed background to go along with it.
|Type of Error||Description||Images|
|Down For Maintenance||Main article: Maintenance
"We'll Be Back Soon"
"We're making things more awesome. Be back soon."
"This site is currently offline for maintenance and upgrades. Please check back soon!"
The error message may not always have the password text box depending on reason for maintenance.
Even if Roblox isn't offline for maintenance, you can view the new maintenance page at https://www.roblox.com/offline.html
|Too Many Redirects||The message varies depending on the browser:
The page isn’t redirecting properly (Firefox)
This page isn't working; www.roblox.com redirected you too many times (Chrome)
Displayed on accounts with a poison ban. This error occurs because the site tries to redirect to the Membership/CreationDisabled.aspx page, but when banned, all pages redirect back to Membership/NotApproved.aspx, creating an infinite redirect loop.
|Updating Avatar Error||"Items you don't own in this outfit: (X)"|
|Something went wrong||"Error | An unexpected error occurred. Please try again later."
Displayed when changing the error number in the error page URL to a non-existent error number.
|Bad Request||"400 | There was a problem with your request"
Displayed when the web request made by a device is invalid or otherwise incorrect. It may also happen when searching inventories of completely wiped accounts too (e.g. noli - ID 31042685).
This error is also caused when changing the code in the address bar, or when the Roblox site is experiencing problems.
"403 | You don't have permission to view this page."

|Roblox outage||"The request could not be satisfied."
Also known as a hard 503 error. Displayed when ROBLOX is having downtime or outages, but not for maintenance. Alternatively, entering the URL roblox.com/request-error?code=503 doesn't make this page pop up, instead showing the "bad request" or "Something went wrong" error.
|Connection timed out.||This message varies depending on browser
"This page isn't working: roblox.com took too long to respond." (Chrome)
HTTP 504. Displayed during a web-host timeout, which can be caused by Roblox maintenance/server downtime or by a poor internet connection.

|Invalid Parameter||"Invalid arguments."

Happens when the player tries to friend a user that already has the maximum of friends allowed on Roblox.

|1 (retired)||"Roblox cannot startup. User code = 0x1"|
|2||"Initialization error 2"
This was similar to error code 4.
|4||"Initialization error 4"
Displayed when the launcher cannot initialize properly.
|6||"An error occurred while starting Roblox; Details: ... Error Code: 6"
Displayed when the launcher times out while downloading a new version or launching a game, which can be caused by the faulty internet connection or anti-virus detections.
|"Developer has shut down all game servers or game server has shut down for other reasons, please reconnect (Error Code: 256)"
"The experience's developer has temporarily shut down the experience server. Please try again. (Error Code: 274)"
Displayed when a developer manually closes a game server (usually when updating the game), when a private server owner shuts down the private server, or when a player is banned while in-game.
|260||"There was a problem receiving data, please reconnect. (Error Code: 260)"
Displayed when no data is being received by the Roblox web servers.
|261||"Error while receiving data, please reconnect. (Error Code: 261)"
"There was a problem streaming data, please reconnect. (Error Code: 261)"
Displayed when the server fails to send feedback for data requests, which can be caused by a poor internet connection, Roblox downtime, or other issues.

Displayed when a game cannot load after data fails to send.
|264||"Same account launched game from different device. Reconnect if you prefer to use this device (Error Code: 264)"
"You are already playing a game. Please shut down the other game and try again. (Error Code: 264)"
Displayed when a client starts while another client is already playing a game. This error can indicate an unknown/unwanted user on an account. This error can also occur if the player is warned in-game, but that error code has been replaced with 273 instead of 264. If no internet issues are occurring with the account, this is likely due to the account being compromised and someone else is trying to start a game while the original account owner is already playing a game. When Error 273 occurs, the reconnect button will appear on the right of the Leave Button.
|266||"Your connection timed out. Check your internet connection and try again. (Error Code: 266)"
Displayed when the connection was timed out. This happens when the client's connection lags a lot or has not responded for a long time. It usually appears during a game timeout, which can be caused by a weak internet connection, high ping, or a slow computer.
|267||"You were kicked from this experience: You have been kicked from the game (Error Code: 267)"
"You were kicked from this game: [Reason] (Error Code: 267)"
Also unlike other errors, a custom message can be given in the error message box depending on how you were kicked (not always however; if no reason is given then the game will simply display the default text).
"This game has shut down"
An old version of "You were kicked from this experience" was used from 2006 to 2018/early 2019.
|268||"You have been kicked by the server. Please close and rejoin another game (Error Code: 268)"
"You have been kicked due to unexpected client behavior. (Error Code: 268)"
Displayed when a user is kicked from the game and is forced to join another server. This can occur from general connection issues, and in some cases when using exploits or for having a lot of lag. This error can also occur when using a compatibility layer such as Wine to play the game on Linux.
|271||There are three variations of this error:
|272||"Disconnected due to the Security Key Mismatch (Error Code: 272)

|273||"Disconnected from the game, possibly due to the game joined from another device (Error Code: 273)"
"Same account launched experience from different device. Reconnect if you prefer to use this device. (Error Code: 273)" Identical to error 264, however this error occurs when a user is in-game while warned or banned. The user is kicked from the server and their page reloads, which then shows the user the ban/warn.
|275||"Roblox has shut down the server for maintenance. Please try again. (Error Code: 275)"
"Roblox has shut down this game server for maintenance (Error Code: 275)"
Displayed when Roblox closes a game server for maintenance or if a game is deleted by a Roblox staff member while being played.

This is also the typical error for when the server the player is connected to is getting overloaded and crashing (Attempting to reconnect in this case often results in a code 279 error).
Old versions of this include "You have lost the connection to the game" and "Lost connection to the game server, please reconnect" which were used from 2006 to 2018/early 2019.
