Same here, trying to test updates on a development map and since todays update it has gone through various states of loading until it finally gets to message

“There was an error: network Connection Lost.”

(Takes about 5 mins of loading to then hit this message, so multiple restarts and attempts is making this evening very unproductive!)

Back to doing another restart now!

Actually, on any second attempt it seems to be trying to load it as if it is a published island, with the loading image being a generic edit session lobby and then the 3 bullet points about generic use of UEFN & Verse.

Usually it just goes to the generic lobby without a loading image.

Same here, i cant log in any Creative map, the games when hits the part: Loading, the game just close and thats it, normal matches works just fine but any creative map just crashes my game

New : after working like 1 hour today I launched the first session and get the connection error, then I restarted the editor and launched the session immediatly and it worked once.
So it’s not only after the first session but also after some time.

Same issue here. It was working perfectly yesterday (even after updating the engine). But since this morning I am not able to launch any live edit session from the engine.
It seems it doesn’t impact every member of our team even though we’re all working on a same version of the project.

Thanks all, we’ll get someone to take a look.

I don’t know if it’s related but in my latest island I use the Verse Session stuff from this code :

FindCreativeObjectsWithTag return nothing

haha great, can you try to add a delay before fetching from the NPC maybe ? Otherwise you’ll need to come up with a custom solution like this

But the connection problem wasn’t there before 33.11 update anyway even when using this code.

Maybe too early to tell, but deleting my :
C:\Users[Username]\AppData\Local\FortniteGame
Folder helped me fix launch into session issues (at least fo time being) on 2 of my machines.

Im EU based btw, just in case this is relevant

@Flak i have contents of both folder contents, the old one that crashed and the new one that got regenerated, if thats interesting

EDIT: Thats three times clearing app data folder solved prolem for me once it started happening

CRITICAL - UEFN session not start in Fortnite (map testing not possible !!!)

Thank you. A note for you at this point… I now have a “reasonably working” workaround…: 1.) I start Fortnite first before I start UEFN 2.) When Fortnite has loaded completely, I wait a few minutes and then start UEFN (so I don’t get the login error) 3.) When my UEFN project is fully loaded, I start the editing session IN FORTNITE (I find this under “last played”) 4.) I wait until the loading screen of the editing session appears in Fortnite and then connect the editing session from UEFN at …

maybe this help you
