Error Code 6000.80
Last Updated: September 18, 2025
Question: What can I do about the following error when trying to sign in to the Rockstar Games Launcher?
Online sign in failed. We attempted to fallback to offline sign in but that also failed. The username or password may be wrong or the account may not exist on this machine. Offline play is only available for accounts that have previously signed in on this machine (with “Remember me” ticked) while connected to the Internet and while Rockstar Games Services are available.
Answer: Error Code 6000.80 occurs whenever the Rockstar Games Launcher cannot communicate with Rockstar Games Services. Depending on the cause, one of the following methods should resolve the error:
Verify your account credentials
Check to make sure the username and password for the Rockstar Games account you are signing in to are entered correctly
If you are attempting to sign in using offline mode, try signing in online with “Remember Me” ticked before switching to signing in offline
