Error Code 277

“Lost connection to the game server, please reconnect”

Last Updated: June 2026

There are few things in Roblox more annoying than getting kicked out in the middle of a boss fight or right before you cash in your rewards.

That is exactly what Error Code 277 does. The game freezes for a moment, then a Disconnected box pops up with the caption “Lost connection to the game server, please reconnect. (Error Code: 277)” and all your progress in that round is suddenly at risk.

Unlike join errors that block you at the loading screen, this one strikes while you are already playing. Your device and the game server stopped talking to each other long enough that Roblox gave up and dropped the session.

The Reconnect button works sometimes, but if you keep landing back in the same Disconnected box, something on your device or network needs fixing first.

Well, before you press Reconnect for the tenth time, run through our list of common causes below. One of these is almost certainly behind your random disconnects.

What Causes Error Code 277?

Common Causes:

Unstable internet connection – Short Wi-Fi dropouts and packet loss break the live link between you and the server, even if your speed test looks fine.
VPN or proxy interference – Routing your game traffic through a VPN adds delay and random hiccups that the Roblox connection cannot survive.
Corrupted Roblox cache – Old temporary files pile up over months of playing and can crash the connection mid-session.
Outdated Roblox app – An old version of the Roblox app can also trigger this kind of error due to missing files or incomplete update status of the game.
Roblox server problems – When a game server crashes or Roblox is having an outage, everyone in the lobby gets the same disconnect at the same time.

How to Fix This Error

Stabilize your internet connection

Because Error Code 277 is a mid-game disconnect, the usual suspect is a connection that keeps dropping for a second or two. A speed test will not always show this, so focus on stability instead of speed.

– Restart your router and let it fully reconnect before launching Roblox

– Switch from Wi-Fi to a wired connection if you can, it removes most random dropouts

– Close downloads, streams, and cloud backups running in the background

– If you are on mobile data, move to a spot with a stronger signal or switch to Wi-Fi

Turn off your VPN or proxy

VPNs are great for privacy but terrible for live game connections. The extra hop between you and the Roblox server adds lag spikes that end in the Disconnected box.

Disconnect your VPN or proxy completely, restart Roblox, and play for a while. If the disconnects stop, you found your culprit.

Clear the Roblox cache

Roblox stores temporary files on your device to load games faster, and over time some of those files go bad. Clearing them forces Roblox to download fresh copies.

– Close Roblox completely

– Press Windows key + R, type %localappdata%\Roblox and hit Enter

– Delete everything inside the folder except the Versions folder

– Relaunch Roblox and join a game to rebuild the cache

Update the Roblox app

An outdated Roblox app can cause unusual behavior and unexpected system errors that can also trigger Error Code 277 to occur. To resolve the issue, install the pending updates of the Roblox app to add more files of the latest version to prevent any interruptions while accessing the game.

Check the Roblox server status

If everyone in your server got kicked at the same moment, the problem is on Roblox’s side, not yours. Visit status.roblox.com and check for an ongoing outage before touching any settings.

Join errors behave the same way during outages. If you cannot even get back into a game, our guide on Error Code 279 covers the connection problems that block you at the loading screen.

Re-install the Roblox app

If none of the five troubleshooting methods work, you may consider re-installing the Roblox app to replace any damaged files with a clean copy.

– Uninstall your current Roblox app then restart your PC

– Open your browser and download Roblox

– Once the game is already installed, log in to your account and see if it works

Random disconnects are one of the most common problems on the platform, and every player deals with them eventually. With the fixes above you can rule out your own setup in a few minutes and get back to playing instead of staring at the Reconnect button.
