To Fix the Roblox Error 280, Clear your browser and app-data cache or Go to your device’s settings, find the Date & Time section, and ensure it is set correctly.
What is Roblox Error Code 280?
The official Roblox support page states that Error Code 280 appears when your version of Roblox may be out of date.
But “out of date” is a bit broader: it can also be caused by corrupt cache files, network configuration issues, incorrect system time, firewall/antivirus interference, or even Roblox server-side problems.
So even if your client appears updated, one of the other issues might be preventing Roblox from verifying or updating properly.
Fixes that tend to work
Here’s a checklist of fixes you can try, usually in this order. Try one, test, then move to the next if the issue persists.
⚠️ Make sure to back up any custom stuff (e.g. settings) before deleting files.
Fix | Steps / Notes |
|---|---|
| 1. Restart Roblox / your device | – Close Roblox completely (make sure no background processes remain) – Restart your computer / phone / console – Launch Roblox again and see if it auto‑updates. |
| 2. Sync system date & time | If your system clock is wrong, Roblox might reject update checks. – On PC: set the time to automatic, or manually correct it if “automatic” is wrong – On mobile: enable automatic date/time – Some guides note that wrong date/time is a frequent reason for 280. |
| 3. Clear Roblox cache or residual files | Corrupted cache is a common cause. – On Windows: Use Win + R → %localappdata% → find “Roblox” folders (or %temp%\Roblox) and rename, delete, or clear them.– On Mac: delete Roblox cache in ~/Library/Caches/ or corresponding directories.– On mobile: clear cache/data (on Android) or uninstall & reinstall (on iOS) |
| 4. Reset network settings / flush DNS | If your network is blocking or misrouting Roblox’s update servers, this helps. On Windows:netsh winsock resetnetsh int ip resetipconfig /releaseipconfig /renewipconfig /flushdnsThen reboot. Also power‑cycle your router (turn off, wait a bit, then turn on). |
| 5. Disable or configure firewall / antivirus / security software | Sometimes the security software blocks update access or file writes. – Temporarily disable real-time protection or firewall – If Roblox works, add Roblox (or RobloxPlayer/RobloxStudio) as an exception/whitelist – Be careful: only do this temporarily and restore protections afterward. |
| 6. Disable VPN / proxy | A VPN or proxy can interfere with how Roblox verifies or fetches updates. Turn it off (or bypass it) and try again. |
| 7. Update network driver | An out-of-date or corrupt network driver might break communication. Go to Device Manager → Network Adapters → update driver. |
| 8. Uninstall Roblox completely & reinstall | This is often the “nuclear” fix. – Uninstall Roblox via your system’s uninstall tool – Remove leftover folders (e.g. %localappdata%\Roblox, %appdata%\Roblox, or equivalent on Mac)– Reboot your system – Download and install Roblox again from the official website or store – Launch via the Roblox launcher / client (not via old shortcuts) – Some guides also suggest installing from the Microsoft Store (if on Windows) as an alternative. |
| 9. Use “Repair / Reset” (if applicable) | On Windows, if you got Roblox via Microsoft Store, sometimes you have “Repair” or “Reset” options under Apps & Features. |
| 10. Check Roblox server status / wait it out | If Roblox’s update servers are down or experiencing issues, even a correct client may not get recognized. Use sites like Downdetector or Roblox’s official status page. |
| 11. Advanced / fallback | – On Windows, you can run sfc /scannow to check for corrupt system files that might interfere.– As a last resort, some users have done a clean OS reinstall (that’s extreme). – Also, some Reddit users report that renaming or deleting the Roblox folder before reinstalling is crucial — just uninstalling alone didn’t always fix it. |

What many users report worked for them
On Reddit, numerous users confirm that uninstalling Roblox, deleting Roblox cache (especially
%LocalAppData%/Roblox), restarting the PC, then reinstalling Roblox resolved Error Code 280.Some say that not clearing the cache properly before reinstalling caused the error to persist even after reinstall.
A few users also mention that switching to the Microsoft Store version of Roblox (if on Windows) solved the problem when the web-installer version failed.
Example: Step-by-step for Windows PC
Here’s a sample step-by-step procedure you can try if you’re on Windows:
Close Roblox completely (check Task Manager for any lingering Roblox processes).
Open Date & Time settings → enable “Set time automatically” (or manually correct).
Press
Win + R, type%localappdata%, go to the Roblox folder and rename it (e.g. toRoblox.old) or delete it.Press
Win + R, typecmd, run as administrator, then run:Reboot your PC.
Uninstall Roblox via Settings → Apps (or Control Panel).
Remove leftover Roblox folders (if still present) from
%appdata%,%localappdata%, etc.Turn off firewall / antivirus temporarily.
Visit the official Roblox site, download the installer, and install Roblox.
Launch Roblox via the official app/launcher (not via old shortcuts).
If it works with firewall disabled, add Roblox to exception/whitelist and re-enable protection.
If it’s still not fixed, it may be something deeper — system file corruption, OS interference, or a rare OS-level restriction.
