Satisfactory AMP Instance Crashes on World Creation – Signal 6 Exit

OS Name/Version: Debian 12

Product Name/Version: (Always use the full version number - not ‘Latest’)

Problem Description:

I’m running AMP in a fresh LXC container on Proxmox (Debian 12 base), and installed a new Satisfactory instance. When attempting to create a new world or upload an existing .sav, the server crashes during map load.

The crash occurs consistently, with the server exiting unexpectedly after this log output:

Other important context:

  • I have tried this on a fresh VM install (using proxmox), and even created a new LXC container specifically to get a completely fresh install with JUST Satisfactory on it
  • My original implementation was not using Docker, but the fresh container I made WAS installed using Docker, just to test, same issue.
  • I have firewall rule sin place for ports 7777, 150000, and 15777
  • I’ve been troubleshooting with a friend who has the exact same setup (Proxmox, using Docker) - he was able to spin up a server just fine. When he connects to mine, he goes to create a game, and it fails, bringing him back to the “Create Game” screen - same thing happens for me.

Log from when I try to create a game:

LogNet: Browse: /Game/FactoryGame/Map/GameLevel01/Persistent_Level...
LogGame: Waiting for level streaming...
CrashReportCoreLog: Final state (Receiver) = Unknown UploadState value
LogCore: Engine exit requested (reason: CrashReportClientApp RequestExit)
LogExit: Preparing to exit.
LogExit: Object subsystem successfully closed.
LogExit: Exiting.
Engine crash handling finished; re-raising signal 6 for the default handler. Good bye.

Steps to reproduce:

  • Create a fresh instance
  • Add the server to Server Manager, connect, and accept the fingerprint
  • Go to “Create Game”
  • Click Start, server says Preparing game, then crashes back to “Create Game” menu

Actions taken to resolve so far:

  • Created a brand new LXC container with a clean install of AMP and Satisfactory
  • Open up multiple other ports
  • Confirmed AMP instance has the correct permissions
  • Attempted to upload save files and load into them

I get a similar error when trying to load into a save I created in single player first:

LogWorld: BeginTearingDown for /Game/FactoryGame/Map/DedicatedserverEntry
LogNet: World NetDriver shutdown FGDSIpNetDriver_2147482283 [GameNetDriver]
LogExit: GameNetDriver FGDSIpNetDriver_2147482283 shut down
...
CrashReportCoreLog: Final state (Receiver) = Unknown UploadState value
LogCore: Engine exit requested (reason: CrashReportClientApp RequestExit)
Engine crash handling finished; re-raising signal 6 for the default handler. Good bye.
