Roblox Disconnect Errors: How to Fix Error Codes 277, 279, and 267

#troubleshooting

Getting disconnected in the middle of a Roblox raid, a competitive match, or a high-stakes trade is incredibly frustrating.

When that dreaded disconnect screen pops up, it usually displays one of three error codes: 277, 279, or 267.

The mistake most people make is trying random "fixes" they found on a forum without knowing what they’re actually fixing. These three errors look similar on the surface, but they stem from completely different parts of your system. One is a network drop, one is a firewall block, and one is an intentional kick from the game itself.

Let’s break down exactly what each code means and how to fix it properly.

The Quick Diagnostic Cheat Sheet

Before you start digging into settings, match your error message to its actual cause:

  • Error 277: "Please check your internet connection..." The Cause: Your PC lost contact with the Roblox server for more than 10 seconds. This is usually a Wi-Fi packet drop or a router glitch.
  • Error 279 (ID=17): "Failed to connect to the Game..." The Cause: A handshake timeout. Your Windows Firewall or router is blocking Roblox from talking to the server, or your DNS is failing to resolve the address.
  • Error 267: "You have been kicked from the game..." The Cause: This is not a network error. A script written by the game developer intentionally kicked you.

Part 1: How to Fix Error Code 277 (The Connection Drop)

Error 277 happens when your computer and the Roblox server stop exchanging "heartbeat" packets. It’s a transport layer failure.

Instead of restarting your router five times, start by clearing out stale network data on your PC. Old routing tables can sometimes send your game traffic to the wrong place.

The Fix: Reset your network stack

  1. Click the Start menu, type cmd, right-click Command Prompt, and select Run as Administrator.
  2. Type the following commands one by one, pressing Enter after each: 
   ipconfig /flushdns
   netsh int ip reset
   netsh winsock reset
Enter fullscreen mode Exit fullscreen mode
  1. Restart your computer and try joining the game again.

If you’re on Wi-Fi, also try moving closer to your router or switching to a wired Ethernet connection. Wi-Fi is notorious for micro-drops that trigger this exact error.

Part 2: How to Fix Error Code 279 (The Firewall Block)

Error 279 (often accompanied by ID=17) means your game client is trying to connect, but something is standing in the way. Nine times out of ten, that something is Windows Defender Firewall.

When Roblox updates, the firewall sometimes treats the new executable file as an unknown threat and blocks its outgoing connections.

The Fix: Allow Roblox through the Firewall

  1. Press the Windows key, type Windows Defender Firewall, and open it.
  2. On the left sidebar, click Allow an app or feature through Windows Defender Firewall.
  3. Click the Change settings button at the top (you may need admin rights).
  4. Scroll down the list and look for Roblox or Roblox Player.
  5. Make sure the checkboxes for both Private and Public are ticked.
  6. Click OK and restart Roblox.

Note: If you use a third-party antivirus (like Norton or McAfee), you will need to find the firewall settings within that specific app and add Roblox to its exception list.

Part 3: How to Fix Error Code 267 (The Script Kick)

This is the most misunderstood error. Error 267 is not your internet’s fault. It means the game’s code actively executed a player:Kick() command against your account.

To fix this, you have to read the fine print. Look at the secondary message right below the error code. It usually tells you exactly why you were kicked.

Common reasons for a 267 kick:

  • Account Age Restrictions: Many trading or competitive games automatically kick accounts that are less than 7, 30, or 60 days old to prevent botting and alt-account abuse. The only fix here is to wait until your account ages up.
  • Anti-Cheat False Positives: If your game suddenly lagged, froze, or you experienced a massive FPS drop, the server might have registered your character teleporting across the map. The anti-cheat script interprets this as "speed hacking" or "noclip" and kicks you. Fixing your Roblox FPS drops usually solves this.
  • VPN or Proxy Usage: Many developers use IP reputation tools that instantly kick players connecting from known commercial VPN data centers. If you’re using a VPN, turn it off and try again.

The Bottom Line

Troubleshooting is just process of elimination.

If you see 277, reset your network stack.

If you see 279, check your firewall.

If you see 267, read the kick message and check your account status or VPN.

Stop guessing and start targeting the actual root cause. It saves time, and it gets you back in the game a lot faster.
