Roblox Error Code 277: How to Fix the Disconnection Error

Error Code 277 shows up as “Lost connection to the game server, please reconnect” — and it’s one of the most common disconnects on Roblox. It’s a catch-all for a broken link between your device and the game server, and in most cases it’s genuinely fixable in a few minutes.

What Does Roblox Error Code 277 Mean?

Error 277 means your device was connected to a Roblox game server and then lost that connection mid-session. It’s a general-purpose disconnect code, which is why it can be triggered by several different things — a shaky home network, a corrupted local cache, or even a problem on Roblox’s end.

Common Causes

• Unstable Wi-Fi — especially on the crowded 2.4GHz band, which is more prone to interference from other devices.
• Corrupted temporary files in Roblox’s cache or your device’s temp folder.
• Router issues — a router that’s been running for weeks without a restart can develop routing errors.
• A Roblox server-side outage — if it’s affecting everyone at once, there’s nothing to fix locally except wait.

How to Fix Roblox Error Code 277

Roblox’s own support team specifically recommends reinstalling the app, checking your system date and time, and testing a different internet connection. Beyond that:

1. Power-cycle your router and modem. Unplug both for a full 60 seconds, plug the modem back in first, wait for it to come online, then the router.
2. Switch to Ethernet if you can, or move to the 5GHz Wi-Fi band — it’s less crowded and drops fewer packets than 2.4GHz.
3. Clear Roblox’s cache (delete the contents of %localappdata%Roblox on Windows) so the client rebuilds its files clean.
4. Check Roblox’s server status before troubleshooting further — if it’s a platform-wide outage, nothing on your end will help until Roblox fixes it.
5. Verify your system clock is set to automatic/correct — an incorrect date can break the secure connection Roblox needs to authenticate you.

Still Disconnecting?

If 277 keeps happening on every network and every device, it’s worth ruling out account-side causes too — see our guide to general Roblox connection problems for the full troubleshooting path, including when the fix is actually on Roblox’s end.

Frequently Asked Questions

Does Error 277 mean I’m banned?
No. It’s a connection error, not an account restriction. Bans show different, more specific error codes.

Why does it happen mid-game and not at login?
Because it’s a dropped connection, not a failed login — it can happen at any point once you’re already inside a game server.
