Error

An error is a piece of information displayed when an unexpected event occurs. Error messages are used when user intervention is required, to indicate that a desired operation has failed, or to relay important warnings (such as warning a computer user that they are almost out of hard disk space). Error messages are seen widely throughout Roblox and are part of every Roblox version.

In Roblox, if an error has occurred in the game, a dialog box will show up with a message, usually requiring the player to rejoin, causing the game's background to blur.

When on the website, most error messages will be the only content shown on-screen besides the header and footer.

Common website errors are:
 * Unknown error
 * 403 error
 * 404 error
 * 500 error
 * 400 error
 * Bad Request

 * Client Crash
 * Client Crash

A generic error message is displayed if the client has crashed. Can also happen if the client runs out of memory, it can also happen when the player joins with an exploit. This can also be caused by very heavy lag in the game (Over 200 Thousand ms). "An error occurred while starting Roblox; Details: ... Error Code: 6"

It might also happen if the Local Internet or a Government blocks Roblox (extremely rare, since Error Code 610 could appear instead). This error also appears when your internet connection is down or you get banned while playing. As of recent, this has started to occur randomly, even when the connection is not lost. This is something Roblox has yet to fix. Sometimes, when it does this, it gives no warning (no lag of any sorts), and it just (Unluckily) crashes.
