Are you logged into the editor?

4

Running into the same issue

5

I’m logged into the editor and epic games and I’m online, I tried switching off revision control as well. :frowning: @wouter

@LukaTheGameDev could you ZIP your entire Logs directory at C:\Users\wouter.burgers\AppData\Local\UnrealEditorFortnite\Saved\Logsand ZIP up your entire UEFN project that isn’t working and share them with me via Discord? epic.wobu

any update on this?

this bug is super weird, sometimes i can get into session, and then sometimes i cant, its a on and off type of thing. the main issue is
[LogHotfixManager] /Game/Athena/Balance/DataTables/CashPricingItemDef.CashPricingItemDef: Duplicate row name ‘/DrivingNebula/Gameplay/WID_DrivingNebula.WID_DrivingNebula’.

Hi sorry couldn’t get back

Was busy

10

@Wouter I can’t rn because my account for some reason got banned on discord and im sending a message to tech support, although i think its a problem with UEFN and not the project because this happens on all projects and even on blank ones

11

@CletusEsquire I think the main problem is:

LogVkScratchRepository: Error: [7b9692fc-1d83-4a8b-8ad1-243db9fb2773][Create] creating repository on server: code: ‘The request does not have valid authentication credentials’, message: “authorization header required”

However i’m not sure how to get valid authorization

13

I haven’t been able to test this fix multiple times yet, but so far verifying Unreal Editor’s game files and restarting the Epic Games Launcher has fixed this issue for me.

15

Hi, I randomely edited a project

  1. Placed a Accolades device

2)clicked on compile verse

3)Clicked on start session and it worked.

I’m not sure what happened but the problem fixed itself. @CletusEsquire I don’t know what you should do and if the problem persists you can make a new bug report like this one. Thanks for all the help everyone but I think this should still get accesed as it is happening to other poeple. NOTE: I have tried this solution before and multiple others but all of them failed till know. @wouter @eemBee @Bug-Reporter

I have chosen to keep the forum up becuase other poeple are experencing this issue and it would be nice if it got fixed, if you wish for me to close this forum please tell me.

Sometimes I start session but fortnite doesn’t start leaving it waiting for client but the client isn’t being launched or sometimes it takes too long to download so it stops starting session

FORT-1162625 is ‘Closed’ as ‘Fixed’. The issue will be addressed in .
