Roblox Error Code 277: Meaning, 279 Difference, and Safe First Check
Roblox describes Error Code 277 as losing the connection to the game server, or the client failing to establish a network connection, after you were already joining or playing an experience.
Quick answer
A 277 appears when the session started and then the game-server connection dropped. That is different from Error 279, where the connection never establishes. The useful answer is to isolate whether the disconnect follows Roblox service status, one experience, your network, or a single device before reinstalling anything.
Why players search it
- They want to know what the "lost connection" message actually means.
- They need to tell a 277 disconnect apart from a 279 join failure.
- They want the safe first check before reinstalling Roblox or changing security settings.
Quick facts
- Best read as
- Lost connection to the game server after joining

- Low for meaning; live status changes hourly
Search scenarios behind this query
- A player is disconnected part-way through an experience and sees "Lost connection to the game server, please reconnect".
- One experience keeps dropping while other experiences stay stable on the same device.
- A disconnect happens on one network but not on a second trusted network.
How to verify what you are seeing
- Check the official Roblox Status page for a games or joining incident before changing the device.
- Join a second well-known experience; if only one experience drops, preserve that clue instead of reinstalling.
- Compare another device on the same network, then another trusted network on the same device, to place the fault.
Quick checks before you trust a guide
- Did the session start first and then drop (277) rather than never connect (279)?
- Does the official status page show a current games or joining incident?
- Does the disconnect follow one experience, one device, or one network?
Player workflow
What to do next
- Read the message and confirm it is a lost-connection 277, not a 279 join failure.
- Check the official Roblox Status page for a games or joining incident and wait for a timestamped recovery during an outage.
- Join a second well-known experience, then compare another device and another trusted network to place the fault.
- Only after those checks, follow the official device-specific repair path for your platform instead of third-party fixers.
Common mistakes
- Treating 277 and 279 as identical when one is a disconnect and the other is a failed connect.
- Reinstalling Roblox during an outage before checking official status.
- Installing an executor, modified client, or unofficial "277 fixer" that asks for credentials.
