Got an error code and no idea what it means? This guide covers every common Roblox error code with a plain-English explanation and step-by-step fix.

Before You Start: Universal Fixes

These steps fix the majority of Roblox errors regardless of the specific code. Try these first before looking up your specific error:

  1. Check if Roblox is down — visit our Is Roblox Down? page. If the servers are having issues, waiting is the only fix.
  2. Restart Roblox — close completely and reopen
  3. Restart your device
  4. Check your internet connection — run a speed test or try loading another website
  5. Clear Roblox cache — in the Roblox app settings, or delete the Roblox AppData folder on Windows
  6. Reinstall Roblox — uninstall completely, download fresh from roblox.com

Connection and Network Errors

Error 277 — “Disconnected from Game”

What it means: You lost connection to the game server mid-session.

How to fix:

  • Check your internet connection
  • Move closer to your router if on Wi-Fi
  • Switch from Wi-Fi to a wired ethernet connection if possible
  • Restart your router
  • Check if your internet provider is having issues

Error 279 — “Failed to Connect to Game”

What it means: Roblox can't establish a connection to the game server in the first place.

How to fix:

  • Check your firewall — Roblox needs ports 49152–65535 open
  • Disable any VPN — VPNs frequently cause connection failures
  • Temporarily disable antivirus software and try again
  • Try a different network (mobile hotspot to test)
  • Flush your DNS: open Command Prompt and type ipconfig /flushdns

Error 503 — “Game Unavailable”

What it means: The specific game's servers are full or temporarily unavailable.

How to fix:

  • Wait a few minutes and try again
  • Try joining a different server within the same game
  • Check if the game itself has been taken down by its developer

Error 769 — “Teleport Failed”

What it means: A teleport between places within a game failed.

How to fix:

  • Rejoin the game from the beginning
  • Check your internet connection
  • If it happens consistently in one game, the game may have a developer bug — try a different game

Login and Account Errors

Error 403 — “Access Denied” / “Forbidden”

What it means: You don't have permission to access this page or feature. Often happens when trying to access age-restricted content or pages you're not supposed to see.

How to fix:

  • Make sure you're logged in
  • If you're under 13, certain features are restricted — this may be intentional
  • Clear your browser cookies and cache, then log in again
  • Try a different browser

Error 400 — “Bad Request”

What it means: Something went wrong with the request your browser sent to Roblox.

How to fix:

  • Refresh the page
  • Clear your browser cache
  • Try in an incognito/private browser window
  • Try a different browser

Error 500 — “Internal Server Error”

What it means: A problem on Roblox's end, not yours.

How to fix:

  • Wait and try again — this is usually temporary
  • Check roblox.com/status to confirm it's a server-side issue

Game Join and Loading Errors

Error 267 — “Kicked from Game”

What it means: You were removed from the game, usually by an anti-cheat system or a game admin.

How to fix:

  • If you weren't cheating, the anti-cheat may have triggered incorrectly — try rejoining
  • If you were using exploits or cheats, stop — Roblox can ban accounts for this
  • Make sure no unauthorized third-party software is running

Error 524 — “Not Authorized to Join This Game”

What it means: You don't have access to join the game. Either it's private, VIP-only, or requires Roblox Premium.

How to fix:

  • Check if the game requires Roblox Premium — you may need to subscribe
  • Check if the game is private — you may need an invite from the owner
  • Some games use VIP servers — you need to be invited or pay for access

Error 901 — “App Not Installed” or Store Error

What it means: Roblox can't communicate with the device's app store (usually on mobile).

How to fix:

  • Update Roblox to the latest version
  • Update your device's operating system
  • Uninstall and reinstall Roblox

Windows-Specific Errors

“Roblox Has Crashed”

How to fix:

  • Update your graphics drivers
  • Lower Roblox graphics settings (in-game Settings → Graphics Quality → drag left)
  • Run Roblox as administrator
  • Check if your PC meets minimum requirements: Windows 7 or later, 1GB RAM minimum (4GB recommended)

“Roblox Won't Launch” / No Error Code

How to fix:

  1. Press Win + R, type %localappdata%\Roblox and press Enter
  2. Delete everything in this folder
  3. Reinstall Roblox from roblox.com
  4. Make sure your antivirus isn't blocking Roblox — add it to your whitelist

“DirectX / Graphics Error”

How to fix:

  • Update DirectX (download from Microsoft's website)
  • Update your graphics card drivers
  • Switch Roblox to OpenGL mode: in Roblox Settings, change renderer to OpenGL

  1. Go to System Preferences → Security & Privacy
  2. Click Open Anyway next to the Roblox message
  3. If the button isn't there, try right-clicking the Roblox app and choosing Open

“Failed to Install Roblox” on Mac

How to fix:

  • Make sure you're running macOS 10.13 or later

Still Not Fixed?

If none of the above worked:

  1. Search the exact error code on the Roblox Developer Forum (devforum.roblox.com) — developers often post about specific game errors there
  2. Contact Roblox Support at roblox.com/support — include your username, the error code, what you were doing when it happened, and your device/OS
  3. Check our Is Roblox Down page — sometimes widespread errors are server-side and you just need to wait

FAQs

Q: Why does Roblox keep disconnecting me?
Most disconnections are network-related (Error 277). Check your connection stability, move closer to your router, or switch to ethernet.

Q: Error 267 — was I banned?
Not necessarily. Error 267 means you were kicked from a specific game, not banned from Roblox. You should still be able to play other games. If you can't log in at all, that would be an account ban — check your email for a notice from Roblox.

Q: My error code isn't on this list.
Search for the code at roblox.com/support or the Roblox Developer Forum. New codes are added occasionally.
