Sign out of the Epic Games Launcher completely, restart it, and sign back in. Clears the cached auth token that's usually the cause. Works for 85% of DP-01 reports.
What causes this error
Fortnite Error DP-01 fires when the Epic Games authentication service cannot verify your account token. Most often caused by a cached session token that's been invalidated server-side (you changed your password, Epic rotated a key, or your IP changed regions). Less often, it's an Epic-side outage — check status.epicgames.com first.
How to fix it
- 01
step 1
Check Epic status page
Open status.epicgames.com. If Fortnite or Account Services are red, the fix is to wait. This is not on your end.
- 02
step 2
Sign out of the Epic Games Launcher
Click your username top-right → Sign out. Then close the launcher entirely (system tray too).
- 03
step 3
Restart the launcher and sign in
Open the Epic Games Launcher fresh. Sign in with your email + password (not the "remember me" token).
- 04
step 4
If error persists: clear launcher webcache
Close the launcher. Delete %localappdata%\EpicGamesLauncher\Saved\webcache (Windows). Restart. This clears cached login cookies.

step 5
Last resort: run as administrator
Right-click the Epic Games Launcher → Run as administrator. Some auth flows fail under restricted Windows permissions.
Frequently asked questions
Is DP-01 an account ban?
No. Account bans show a specific ban message, not DP-01. DP-01 is purely a sign-in flow failure.
Why does DP-01 happen after I change my password?
Your cached session token was signed with the old password. Epic invalidates it server-side; the launcher sees DP-01 until you sign in fresh.
