Roblox Error 301 indicates an anti-cheat system kicked your session. Developer-implemented anti-cheat scripts monitor player behavior for patterns consistent with exploiting. Legitimate players can occasionally trigger false positives, particularly if a third-party program was detected interfering with Roblox's memory.

False positives
Overlay software (Discord, GeForce Experience, screen recorders), modded game files, or programs that monitor memory can trigger developer anti-cheat scripts even if you are not exploiting. Close background software and retry.
Roblox's own detection
If Roblox's platform-level detection kicked you, and you were not using any unauthorized software, contact Roblox support at roblox.com/support to review the kick.
How to fix step by step
- 1Close all background software (overlay apps, screen recorders, performance monitors) before launching Roblox
- 2Verify your Roblox installation is unmodified — uninstall and reinstall if in doubt
- 3If the kick was from a specific experience's anti-cheat, try other experiences to confirm the issue is experience-specific
- 4Contact Roblox support if you believe it was a false positive from Roblox's own detection
How 301 differs from related codes
- Error 403: Roblox refused access to the requested resource or experience. (server or client)

- Error 6: Roblox was unable to establish a connection to the game server. The client timed out before a session could be created. (server or client)
