Bug Report: UEFN Stuck on "Connecting..." – Cannot Launch Any Session

Summary UEFN is completely unable to launch a session. On any project — including brand new, empty projects — clicking Launch Session causes the editor to hang indefinitely on “Connecting…”.

This fixed it for me:

1. Logged into a different Epic account in UEFN.,

2. Logged back into my main account.,

3. Went to Epic Account Settings → Password & Security → clicked “Sign Out Everywhere.”,

Sessions now launch normally.

In addition to troubleshooting steps metioned previously:

• At the time, reinstalling the Epic Games Launcher didn’t work

I was half way through trying a clean install on a different drive (the integrity of my drives were fine btw, sfc /scannow returned nothing) when the tuesday update happened.

Mine works 100% of the time now (I’m in OCE servers).

I suspect it had something to do with the FortniteStatus twitter account investigation, or the update.
