Error code 275 means Roblox shut down the game server you were on, usually for maintenance or a platform update. It can also appear if the experience itself was removed while you were playing. There is nothing wrong with your device or your account.
If 275 appears every time you try one specific experience over several hours, the game may have been taken down by its developer or by Roblox, and no local fix will bring it back. If it appears across all games for a long time, check the status page again, since a longer maintenance window or outage is the likely cause.
How long does error 275 last? Usually only a few minutes, since most maintenance shutdowns are brief. Platform-wide maintenance can take longer, and the status page is the best place to check.
Did I lose my progress when the server shut down? That depends on the game. Most experiences save progress regularly, so only the last few moments may be lost. Games that only save on leaving can lose more.
Is error 275 caused by my internet? No. It means the server itself was closed by Roblox, not that your connection dropped. A connection drop shows a different code, such as 277.
