- For error messages in general, see wikipedia:Error message.
A game client error message (without the message).
New variant of "Not enough robux" error message.
An Error Message is usually displayed when an unexpected event has happened within a program. This includes errors encountered in Roblox Player, in Roblox Studio and on the website.
There are three types of errors on Roblox: website (HTTP) errors, which prevent a client (user) request from working, program errors (including engine errors), which terminate the program in most cases, and in-game errors (including Lua errors), which happen within a place and do not terminate the program. In-game errors are different from glitches as glitches usually do not cause an error message to be displayed and are harder to troubleshoot.
If an error has occurred within a game (separate from the program itself), rather than terminating the program, a grey box will appear displaying the information about what happened, prevents any further gameplay in most cases, and will give the player a Leave option, which will bring the player to the website, and a Reconnect option if possible. There are many in-game error messages that can be encountered, each of which is associated with an error code number. Generally, 2xx error codes indicate connection issues, 5xx error codes indicate player-related error, the error code 610 indicates HTTP issues and 7xx error codes indicate place teleportation error.
Different request error pages on the website can be accessed through "https://www.roblox.com/request-error?code=" followed by an error code (such as 400, 403, 404 or 500).
In Lua, error messages are displayed in the output in Roblox Studio, and in the in-game Developer Console. The error function can be used to generate an error message, which will also stop the thread that called the function from continuing.
Website errors
| Error | Description | Images | |

| Maintenance |
Displayed when the administrators have locked down the site to fix something that went wrong in the background. This screen is also used when the site is closed for maintenance. This is what the test websites currently lead to. The buttons spelling out Roblox and the text box are used when the administrators need to enter a password to start making changes to the website. Google Chrome sees this error as a soft-503 error. The error message may not always have the password text box depending on the 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 |

  |

  |
| 260 |

| 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/banned 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 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. This error also appears if a user rejoins a game too quickly, or sometimes when a server completely crashes, |
    |
| 266 |

| 271 |
|
      |
| 272 |
Displayed when the user attempts to join the game while an exploit is loaded. |
    |
| 273 |
Identical to error 264, however, this error occurs when a user is in-game while warned, banned or terminated. The user is kicked from the server and their page reloads, which then shows the user the ban/warn. In most cases when pressing reconnect upon being banned with code 273, error code 769 or 773 will show. But it may also happen if the same account launches a game. The same Error Code and Reconnection aftermath can occur if a user presses ''log out from all other sessions'' in the security Tab while in-game. |
    |
| 274 |
Displayed when a developer manually closes a game server (usually when updating the game) or when a private server owner shuts down the private server. Reconnecting will sometimes display error code 773. |

Displayed when Roblox closes a game server for maintenance or if a game is deleted by a Roblox staff member while being played. Rarely displays when the private server owner disables "Allow Joining" in the private server settings |
    |
| 277 |
This is usually displayed when the client has one of many different internet issues while connected to a game, including dropped connection, IP address change, disconnecting/connecting to a VPN, or if the player turns off their wi-fi. Can also occur if Roblox disconnects the server automatically, and attempting to rejoin will often show 279. 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. |

  |
| 284 |

  |
| 292 |
Displayed when Roblox detects low to near insufficient memory to run Roblox. This warning is similar to error code 286, although players who encounter this warning have the choice to keep playing the game or to leave the game.

  |
| 517 |
Displayed when a client attempts to join a server that is in the process of closing, or when a player attempts to rejoin a server before Roblox disconnects them from their previous visit (ID 17/279 may happen too) |

Trivia
This section is a trivia section. Please relocate any relevant information into other sections of the article.
- Error 273 is one of the only errors with a message that is unrelated to the reason, with the reason for the error being due to a user receiving a moderation action in game, while the message is 'Same account launched from different device'. Getting this error for the first time could confuse the player, and make them try to reconnect, before leaving the game to try to resolve the issue, thus showing them the Moderation Notice screen.
