506. Failure connecting to the Rockstar Games Launcher! (ExitCode = 506)

FiveM Client Support

What is the issue you’re having?

Every time I launch FiveM, I get the error “506. Failure connecting to the Rockstar Games Launcher! (ExitCode = 506)”. GTA V Legacy launches normally through Steam and the Rockstar Games Launcher, but FiveM always fails with ExitCode 506. I have already reinstalled GTA V, Rockstar Games Launcher, and FiveM, cleared the FiveM cache, verified the game files, and repaired Windows system files, but the issue still persists.

What have you tried already to fix the issue?

I have already tried:

Reinstalling GTA V Legacy (Steam)
Reinstalling Rockstar Games Launcher
Reinstalling FiveM
Clearing the FiveM cache
Verifying the GTA V game files through Steam
Running sfc /scannow to repair Windows system files
Restarting my PC multiple times
Launching GTA V through the Rockstar Games Launcher before opening FiveM
Running both Rockstar Games Launcher and FiveM as Administrator

Despite all of these steps, FiveM still shows “506. Failure connecting to the Rockstar Games Launcher! (ExitCode = 506)” every time I launch it.

What server did you get this issue on?

None. The error occurs before I can join any server.
