Same here. It’s definitely a server issue.

Same error here!

Potential solution that just allowed me to launch a session:

  1. Remove all Fab content from project files and outliner.
  2. Disable Unreal Revision Control.
  3. Launch session.

Or maybe Epic just fixed the server issue that was causing this issue

in fortnite status supposedly they fixed it but it is still giving me problems.
