UEFN - Unable to Play - Validation Failed - SSL or SSH was not OK

I created another forum post, but i managed to fix up my issue

Unable to create new projects, or load existing projects since the update - General / Issues and Bug Reporting - Epic Developer Community Forums (unrealengine.com)

Attempt these at your own risk, but it fixed this issue for me.

  1. Exit UEFN and Epic Games Launcher.
  2. Browse to: C:\Users\YOUR-USERNAME\AppData\Local\Temp\ .net
  3. Backup the “urc” folder to another location
  4. Delete the “urc” original folder
  5. Relaunch UEFN and everything working again.

I found the issue as everything pointed towards Unreal Revision Control being the issue, so I found the urc.exe file in C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\

I ran that urc.exe to see what would happen and got the following message:

From reading that it sounded like something was corrupt in that urc folder, so deleting it and letting UEFN recreate it seemed to work.
