[UEFN] Publish Error: Timeout(30000ms), unknown_http_500, Can't Publish Project

Hi Epic Dev Team,

I’m experiencing a consistent error when trying to publish my UEFN project via the Creator Portal. Here are the full details:

:small_blue_diamond: Error:
Internal server error, Timeout(30000ms)
SentryEventId: 54fb6d8a80436739eabb5d7d1d416c
Error Code: errors.com.epicgames.creator-portal-api.unknown_http_500

:small_blue_diamond: Project Details:

  • Project Name: gungame1
  • Version ID: 9319-4889-5418
  • Creator: CREATIVE_RTCC
  • Attempted Publish Time: July 4, 2025 @ ~17:30 BST

:small_blue_diamond: What I’ve Already Tried:

  • Restarted UEFN and Epic Launcher
  • Tried different browsers (including Incognito)
  • Created a new private version with small edits
  • Waited and retried multiple times
  • Cleared Unreal DerivedDataCache
  • Verified UEFN installation via Epic Games Launcher
  • Support told me to post here after saying they can’t help directly

:small_blue_diamond: Validation Status:

  • :cross_mark: Download Size: Failed
  • :cross_mark: Memory Usage: Failed
  • :cross_mark: Asset Status: Failed
  • :white_check_mark: Verse Path: OK
  • :white_check_mark: Version Type: OK
  • :white_check_mark: Verse Persistence: OK

I also created a brand new private version to see if it would publish, and I’m getting the same timeout error. This seems like a backend issue.

Would appreciate any help or confirmation from the UEFN dev team or anyone else experiencing this. btw this happens to previous versions of this project that went all green before, i havent published any yet though. also its not the whole creator portal because other old projects work fine.

Thanks in advance!
