Direct answer

LS-0021 is usually a launcher-to-service connection problem. Check Epic's live status first, then refresh the launcher session and local connection.

Before you start

Close Epic Games Launcher from the system tray, then restart the PC once. Confirm the Fortnite install drive is connected before using Verify.

Platform note

On Windows, use the launcher’s Verify option before deleting folders or reinstalling. Verification is the least destructive repair step.

Fix it step by step

Follow these steps in order. Stop when the code clears; deleting files or resetting accounts should never be the first response.

  1. 1

    Open the FortRift status page and check Epic services.

  2. 2

    Restart Epic Games Launcher.

  3. 3

    Sign out and back in once.

  4. 4

    Restart the router if other online services are also failing.

If the code still appears

  1. Take a screenshot that includes the full code and the moment it appears.
  2. Note your platform, Fortnite version, connection type and the steps already completed.
  3. Check the live Fortnite status one more time.
  4. Use Epic Player Support with those details if the problem remains while services are operational.
