Check Epic Games and Patreon Server Status

Sign Out and Back Into the Epic Games Launcher

Unlink and Re-Link Your Patreon Account

Reinstall the Epic Games Launcher
Back up any game save data that is stored locally (not cloud-synced) before reinstalling. Check each game's save location in the launcher before proceeding.

When to Call a Professional
If you have completed all steps above — including relinking accounts, clearing the cache, and reinstalling the launcher — and error IS-PT01 continues to appear, the issue is likely on the server side or involves a deeper account-level problem. Contact Epic Games Support at epicgames.com/help and file a support ticket referencing error code IS-PT01. Also contact Patreon Support at support.patreon.com if the issue appears to be on Patreon's end (for example, if you cannot authorize the Epic Games connection from within your Patreon account settings). Both support teams can investigate server-side sync failures and account linking errors that cannot be fixed by end users.Frequently Asked Questions
What does Epic Games error code IS-PT01 mean?
IS-PT01 means the Epic Games Launcher attempted to sync with Patreon's partner integration system but failed. This sync is used to connect Patreon membership benefits to your Epic Games account. The error is usually caused by an expired authentication token, a broken account link, or a temporary server issue on either Epic Games' or Patreon's side.
Will error IS-PT01 stop me from playing my games?
In most cases, no. Error IS-PT01 is specifically related to the Patreon partner sync feature and should not prevent you from launching or playing games you already own. However, any in-game benefits or content tied to your Patreon membership may be unavailable until the sync issue is resolved.
How do I unlink Patreon from my Epic Games account?
Log in to your Epic Games account at epicgames.com/account/connections. Find the Patreon entry under 'Connected Accounts' and click 'Disconnect.' You should also remove the Epic Games connection from your Patreon account by going to patreon.com, navigating to Settings > Apps & Connections, and revoking Epic Games' access. After doing both, wait a minute and then re-link the accounts.
Is IS-PT01 an Epic Games server problem or a problem on my end?
It can be either. Start by checking epicgames.com/status and status.patreon.com for any reported outages. If both services show as fully operational and other users are not reporting the same error, the issue is most likely on your end — typically an expired token or corrupted cache — and the steps in this guide should fix it.
How long does it take for Patreon benefits to sync with Epic Games after relinking?
After successfully relinking your Patreon account to Epic Games, the sync usually completes within a few minutes. In some cases it may take up to 24 hours for all benefits and entitlements to appear in your Epic Games account. If benefits do not appear after 24 hours and the IS-PT01 error is gone, contact Epic Games Support with your account details.
