What is the difference between error 277 and error 279?

Error 279 is a failure to connect to a game — it happens before you join. Error 277 is a mid-game disconnect — it happens after you have already joined and are playing. Both are network related but occur at different stages of the connection.

Does error 277 cause me to lose game progress?

Yes. Error 277 disconnects you mid-game which means any unsaved progress in that session is lost. Most Roblox games do not have a reconnect with save feature. This is one of the most frustrating aspects of this error.

Why does error 277 happen randomly during gameplay?

Random mid-game disconnects are usually caused by WiFi instability, background downloads consuming bandwidth, or brief ISP interruptions. Use Ethernet and close background apps to minimise random 277 errors.

Can the Roblox server cause error 277?

Yes. If the specific game server you are connected to crashes or restarts everyone in that session gets error 277. In this case there is nothing to fix on your end — simply rejoin the game on a new server instance.
