Can't launch session since new update!!

beam_74 · February 22, 2025, 1:57am

Summary

Hi,
Ever since today’s Fortnite update, I’ve been unable to launch a session in UEFN. This issue is only affecting one specific project—my other projects are working fine. When I try to launch a session, I’m just stuck in the UEFN lobby, and after about 5 minutes, I receive errors.

Everything was functioning perfectly before the update. I have already tried restarting my PC, restarting Fortnite & UEFN, disabling revision control, and testing different snapshots of the project. I even tried deleting all assets and actors, but unfortunately, nothing has resolved the issue.

If anyone has any suggestions or solutions, I would truly appreciate your help, as I’d love to avoid losing all the hard work that has gone into this project.

Below is my output log for reference:

FORT-864635 has been created and its status is ‘Unconfirmed’. This is now in a queue to be reproduced and confirmed.

Yes I’ve been having the same issue fora while without any type of fix, @Flak this is the most up to date information and the problem is same as mine, unable to do anything at all with my project!

Hardcawcanary · February 22, 2025, 8:15am

I have a project that often won’t launch after a UEFN update unless I rebuild HLODs for it

Craxii · February 22, 2025, 8:16am

Is it similar error? Because the thing is even if I try remove everything or revert back to old snapshots from revision control where this issue wasn’t present, it does nothing other than show the same problem

I even attempted deleting HLODs

Quick Update:
I tried building HLODs again, it didn’t seem to fix the problem at all, thank you for your answer although

Hardcawcanary · February 22, 2025, 9:26am

I can’t remember the errors thrown, but your lucky if it actually points out a problem other than a sync failure
But if youve built HLODs before launching then I guess thats not the issue.

Have you done a Build Landscape (ignore all yellow warnings and deselect them with the Show button) to see if you have any Red errors ?

If there is a problem in the HLOD and it’s holding old obsolete references, the Delete HLODs from the build menu seems to miss these and making a totally new HLOD layer works.
From trial and error, the best way to Delete HLODs, IF they are corrupted

This is how I replace HLOD Layer (pasted from a text file)

Close Fortnite Edit/Play Mode if its running
Check-in Changes and make a snapshot with URC for backup
Make a new HLOD Layer in Content Browser - Right Click>World>HLOD Layer
Delete existing HLOD Layer - Replace References to the new one - DON’T Save - When it asks, otherwise it will keep the bad references in the HLOD
Double Click on Level Thumbnail in Content Browser to reload map, can save if prompted
Do a Build Landscape - ignore Yellow Warnings - use drop down filter to deselect them - deal with any Red Errors
Double Click your Level Thumbnail again, Save.
Build HLODs
Try to launch session

If the build is successful but the launch is a failure, then I think you can rule out HLODs as the issue.

Hardcawcanary · February 22, 2025, 9:29am

Yeah it must not be HLOD related…

If your errors the same, maybe you can find out what you have in common, it would be a good place to start troubleshooting.

Sequencers, AI, Foilage, using Custom assets ?

We are also experiencing this issue on our project since the update. “Failed to create module version. Connect to the server failed.”

The issue seems to be fixed! Everyone go check your projects
