How to Fix Roblox Error 268 (Kicked for Unexpected Client Behavior)

By FixMyError · Updated October 13, 2026 · 7 min read

What error 268 means

Error 268 is Roblox's way of saying its anti-cheat didn't like something it saw on your machine. The full message reads "You have been kicked due to unexpected client behavior," and it lands in the middle of a session — sometimes seconds after joining, sometimes mid-game. Unlike a connection error, your internet can be perfectly fine while this happens; the problem is on your device, not the network.

Roblox runs a client-side anti-cheat that watches for signs of tampering: injected code, memory edits, speed hacks, and any software that hooks into the game process. When it detects behavior it doesn't expect — whether that's an actual exploit or a legitimate program that looks like one — it errs on the side of caution and kicks you. The good news is that error 268 is a kick, not a ban: you can rejoin right away. The catch is that it will keep happening until you find and remove whatever triggered the detection.

Common causes

• Cheat tools or exploits: any third-party cheat software, script executors, or exploit loaders — even ones running in the background — will trigger 268.
• Legitimate interfering software: game overlays, screen recorders, macro tools, and some RGB or FPS-boosting utilities hook into the client and can be flagged.
• Corrupted game files: damaged or mismatched Roblox client files behave "unexpectedly" from the anti-cheat's point of view.
• Corrupted cache or DNS data: stale or damaged cached files and bad DNS entries can corrupt the client's connection handshake.
• Antivirus or firewall interference: security software that inspects or blocks Roblox's traffic can make the client's behavior look abnormal.
• Outdated client or drivers: an old Roblox client version or outdated graphics drivers can produce glitches the anti-cheat misreads.

How to fix error 268 — step by step

Work through these fixes in order. Try joining a game after each step to see whether the kicks stop.

1. Close interfering software. This is the number-one cause, so start here. If you have any cheat tools, script executors, or exploits installed, uninstall them completely — running error 268 away while they exist won't work. Then close legitimate programs that hook into games: Discord and GeForce overlays, screen recorders, macro/autoclicker tools, and FPS-boosting utilities. Open Task Manager (Ctrl + Shift + Esc), look for anything suspicious or unnecessary under Processes, and end those tasks. Restart your PC to make sure nothing lingers.
2. Restart Roblox completely. A fresh session can clear temporary glitches. Close the Roblox window, then open Task Manager and make sure no RobloxPlayerBeta.exe or RobloxStudioBeta.exe processes are still running — end them if they are. Wait a few seconds, then launch Roblox again from the official website or app, sign in, and join a game.
3. Flush your DNS cache. Damaged DNS data is a classic trigger for 268. Press the Windows key, type Command Prompt, right-click it, and choose Run as administrator. Type ipconfig /flushdns and press Enter — you should see a confirmation that the cache was flushed. Then type ipconfig /release followed by ipconfig /renew and press Enter after each. Restart your computer, then launch Roblox.
4. Clear Roblox's cached data. Close Roblox fully. Press Win + R, type %localappdata%\Roblox, and press Enter. Delete the contents of the logs and downloads folders, and clear out %temp%\Roblox as well. On mobile, open your device settings, find Roblox in the app list, and clear its cache (not its data, so you stay signed in). Relaunch Roblox and test.
5. Check antivirus and firewall. Security software can block or inspect Roblox's traffic in ways the anti-cheat flags. Open Windows Security, go to Firewall & network protection, then "Allow an app through firewall," and make sure Roblox is checked for both Private and Public networks. Then go to Virus & threat protection, then Manage settings, then Exclusions, and add the Roblox player folder as an exclusion. Restart Roblox and try again.
6. Reinstall Roblox. If nothing else worked, the client files themselves may be damaged. Uninstall Roblox from Settings, then Apps, then Installed apps. Delete any leftover Roblox folders in %localappdata%, restart your device, and download a fresh copy from roblox.com or your device's app store. Sign back in and test — a clean install replaces every file the anti-cheat was suspicious of.

Did this fix it? Quick checklist

• You can join games and play without getting kicked
• No cheat tools, overlays, or macro software are running in the background
• The error doesn't follow you to other devices on the same network
• A fresh reinstall produces a clean, fully updated client

If error 268 persists after all six steps, check Roblox's official status page to rule out a wider issue, and make sure your graphics drivers and Windows are up to date. As a last resort, submit a ticket to Roblox Support describing the error, your device, and every fix you've already tried — they can check whether your account was flagged and clear it on their end.
