When I launch UEFN, the session is disconnected immediately.

I’m getting the error message (“Session has expired. Please log in again.”) when I try to launch UEFN.
I have tried:

  • Logging in/out of Epic Games Launcher
  • Reinstalling UEFN and the Launcher
  • Restarting my PC
  • Changing my network

But the issue is still there.
Does anyone know how to fix this or has experienced the same problem?
