How to Fix Roblox Error Code 279 / ID 17
Source-checked About 10 minutes
Answer
Error Code 279 / ID 17 means Roblox could not establish the connection needed to join an experience. Try another experience and a different trusted internet connection first; if the code follows the device, use Roblox's platform-specific reinstall or app refresh below, then verify that the experience reaches its loading screen.
Confirm the failed initial connection
Read the complete dialog and confirm it says Error Code 279 or ID 17 while joining, before the experience loads. If you were already playing and then disconnected, use the Error 277 workflow instead.
Separate an experience issue from a device issue
Try one different known-working experience, then connect the same device to a different trusted internet source. If only one experience fails, report it to its creator; if the alternate connection works, contact the original internet provider.
Reinstall on Windows
On Windows 11, search for Control Panel, open Programs > Programs and Features, right-click Roblox, and choose Uninstall or Uninstall/Change. Reinstall the official app, then select Play on the same experience and confirm it begins loading.
Reinstall and check permission on Mac
In Applications, move Roblox to Trash or select it and press Command-Delete, then reinstall Roblox. If macOS blocks it, open Apple menu > System Settings > Privacy & Security and allow the Roblox app before testing Play again.
Refresh Roblox on iPhone or Android
Force-close Roblox from the device's recent-apps view and reopen it. If Code 279 remains, remove Roblox and reinstall it from the App Store or Google Play, confirm the device date and time are correct, then retry the experience.
Use the matching Fire OS or ChromeOS reset
On Fire OS, open Settings > Apps & Games > Manage All Applications > Roblox and choose Force Stop, then retry the initial join before reinstalling from Amazon. On ChromeOS, update ChromeOS, end Roblox in Task Manager, reboot, and reinstall through Google Play only if the experience still never begins loading.
Verify or escalate the result
Success means the same experience passes its loading screen without Code 279. If it still fails on multiple experiences and trusted networks, record the code, device, OS, experience, time, and network tests for Roblox Support.

If it does not work
- If another trusted network fixes Code 279, return to the original network and contact its provider or administrator; do not disable device security or install a connection fixer.
- If only one experience fails while others load, reinstalling the app repeatedly is unlikely to help; send the experience creator the exact code and timestamp.
- On Windows, Roblox also documents clearing local app data after uninstalling, but that deletes cached local data; use the official article or Roblox Support before taking that broader step.
Sources and verification
Checked against official documentation on . Scope: Windows, macOS, iOS, Android, Fire OS, ChromeOS.
Roblox documents Error 279 / ID 17 as failure to establish a game connection and provides separate recovery by operating system. The retained video is supplementary and may show older or Windows-only controls; use the written platform branch.
