Error Description
When launching Roblox through Delta Executor, the game displays "Error Code: 280 — Your version of Roblox may be out of date. Please update Roblox and try again." The game kicks you to the home screen or closes.
Why This Happens
- 1Delta Executor version is outdated — the version embedded in Delta no longer matches the Roblox server's minimum client requirement
- 2Roblox client on your device is not updated — the local installation is behind the server-enforced version
- 3Corrupted local cache files are providing stale version information during the handshake
- 4Unstable network connection causing the version verification handshake to time out, returning Error 280 as a fallback
- 5Incorrect system time or timezone — TLS certificate validation fails, which Roblox interprets as a version mismatch
- 6Custom DNS or active VPN/proxy blocking Roblox's update verification endpoint
- 7Roblox server-side issue — occasionally Roblox pushes intermediate builds that temporarily trigger 280 for all users
Quick Fix — Try This First
These 3 steps resolve the issue for most users. If they don't work, continue to the detailed platform-specific guide below.
Update Roblox to the latest version from the Play Store (Android) or Microsoft Store (PC)
Download the latest Delta Executor from deltaexecutor.co/download and do a clean install
Clear Roblox cache: Android: Settings → Apps → Roblox → Storage → Clear Cache. PC: delete %LocalAppData%\Roblox\http folder
How to Fix on Android
6 steps — follow in order until the issue is resolved.
Update Roblox from the Play Store
Open Google Play Store → search "Roblox" → tap "Update". If no update is available, uninstall Roblox and reinstall it — the fresh install will pull the latest version from the server. Error 280 is specifically about version mismatch, so this is always the first thing to check.
Update Delta Executor
Go to deltaexecutor.co/download/android, download the latest APK. Uninstall your current Delta first, then install the new version. The Delta team releases patches within hours of Roblox updates — if your Delta is even one version behind, Error 280 can appear.
Clear Roblox Cache and Data
Go to Settings → Apps → Roblox → Storage → Clear Cache, then Clear Data. This forces Roblox to re-download the correct version metadata on next launch. You will need to log in again after clearing data. Launch Roblox once before attempting to use Delta.
Correct Your Device Time
Go to Settings → System → Date & Time → enable "Automatic date & time" and "Automatic time zone". Incorrect time causes TLS handshake failures that Roblox reports as Error 280. Even a few minutes off can trigger this.
Switch Network Connection
Try switching from Wi-Fi to mobile data (or vice versa). If you are behind a school or work network, the network may be blocking Roblox update endpoints. Using a different network often resolves Error 280 when other fixes do not.
Disable VPN and Reset DNS
If you use a VPN, disable it and try again. Custom DNS (like Pi-hole or NextDNS with game filters) can block Roblox version checks. Switch your DNS to Google (8.8.8.8) or Cloudflare (1.1.1.1) temporarily in your Wi-Fi settings.
How to Fix on PC (Windows)
4 steps — start with Step 1 (most common fix).
Update Roblox Client
If using Microsoft Store: open Store → Library → Update Roblox. If using the standalone launcher: delete the Versions folder inside %LocalAppData%\Roblox, then relaunch — Roblox will re-download the latest client automatically.
Update Delta Executor for PC
Download the latest version from deltaexecutor.co/download/pc. Replace the old executable. If the error persists, delete the entire Delta folder and extract a fresh copy.
Clear Roblox Local Cache
Press Win+R, type %LocalAppData%\Roblox and press Enter. Delete the "http" and "logs" folders. These contain cached version data that may be stale. Do NOT delete the "Versions" folder. Restart Roblox.
Flush DNS and Reset Network
Open Command Prompt as administrator and run: ipconfig /flushdns followed by netsh winsock reset. Restart your PC. This clears any DNS cache that might be pointing to old Roblox endpoints.
How to Fix on iOS
2 steps for iPhone and iPad.
Update Roblox from the App Store
Open App Store → search Roblox → tap Update. iOS enforces app updates strictly, so if an update is available and not installed, Error 280 will appear.
Re-sideload Delta Executor
Download the latest IPA from deltaexecutor.co/download/ios and re-sideload it. The old build may reference a Roblox version that no longer exists on the server.
How to Prevent This Issue
Enable auto-updates for Roblox in your app store to stay on the latest version at all times
Update Delta Executor as soon as a new version is available — enable notifications in the app
Clear Roblox cache once a week to prevent stale version metadata from accumulating
Use automatic time settings on your device — manual time can cause cryptographic verification failures
Avoid using VPNs or custom DNS filters that may block Roblox update endpoints
Frequently Asked Questions
Error Code 280 means "Your version of Roblox may be out of date." It is a server-side version check — Roblox compares your client version against the minimum required version and rejects the connection if there is a mismatch. When using Delta Executor, this usually means either Roblox or Delta needs to be updated.
Delta Executor modifies the Roblox client behavior during injection. When Roblox updates, the internal version signature changes, and the modified client may report an incorrect version to the server. Updating both Roblox and Delta to their latest versions resolves this in almost all cases.
Go to deltaexecutor.co/download and download the latest version for your platform. On Android, uninstall the old APK first, then install the new one. On PC, replace the old .exe file. On iOS, re-sideload the latest IPA.
Yes. An unstable connection can cause the version verification handshake to fail or time out. Roblox then falls back to Error 280. Switching from Wi-Fi to mobile data (or vice versa) often resolves this. Also check that your VPN or custom DNS is not blocking Roblox endpoints.
No. Error 280 is a version mismatch issue, not a permanent incompatibility. The Delta team typically patches this within hours of a Roblox update. Check our status page (deltaexecutor.co/status) to see if a patch is in progress.
Android: Settings → Apps → Roblox → Storage → Clear Cache. PC: press Win+R, type %LocalAppData%\Roblox, delete the "http" and "logs" folders. Do not delete the "Versions" folder on PC. After clearing, restart Roblox and try Delta again.
