[CRITICAL] Connection TIMED OUT.

General Issues and Bug Reporting

Summary

Our team is struggling with this issue and can’t find a solution.

Previously, we had around 60k actors and 94k memory usage, and we were at least sometimes able to launch a session. After reworking our logic, optimizing code, reducing actor count, and even commenting out everything in OnBegin in Verse, we are now completely unable to launch a session.

Current state:

~45k actors
Spatial loading is enabled
~80k memory in the center
~90k at the highest point

We don’t understand how this is possible. I’ve spent over 10 hours trying to launch a session, and nothing helps.

At this point, we would really appreciate assistance from a technician to determine whether this is an issue on our side or something else.

I saw that Epic had server issues and marked them as fixed 4 hours ago, but nothing has been fixed for our map. It’s impossible to launch a session, test, debug, and so on. Our workflow is completely stalled.

29k actors. 73k memory. 2 hours of trying lunch session… Nothing.
I need to delete hole project to start session?

5 GB streaming will take a while to load!, this would take 17 minutes to load on my laptop with Wi-Fi 6

Something to do IMHO

Before deleting anything

  1. Now 40.20 is available go to ANOTHER PC do a fresh installation of Fortnite/UEFN.

  2. Restore the project using Unreal Revision Control “sync” function to put a clean version of project on PC use URC selector in the new version where you can select BEFORE the problem occurred.

Cant find the new documentation for URC 2, but its in a posting somewhere and maybe there is documentation.

  1. Next try using an Alternate Epic account in the same team make a new account in the Team

The logs show all your assets are successful validation.

  1. Backup the main project with Zip/Rar and call it something and try loading it onto the new PC.
  2. Check your firewall settings and network settings in past a provider has changed the amount of usage called throttling.

Try to publish a private island get a private island code. set “show in Creative account” using the UEFN Publish function. See what errors you get Memory of Assets will be checked.

Ultimately publishing the island is what development is about

Are you on a 1GB fibre unlimited usage?

WAIT FOR EPIC SUPPORT before deleting anything

if you do delete make a backup first and delete stuff on the backup first
