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 the game, usually on another server. Like an in-game ban, the player will also get disconnected from the game they are playing and may have to close the Roblox game client if the "rejoin" button is grayed out. Prior to the introduction of dialog boxes, a red banner would appear on the screen alongside disconnecting the player.

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
