Sons of the forest fails

Technical Support
1

OS Name/Version:

Windows 11 Pro 24H2 (Build 26200.8655)

Product Name/Version:

AMP 2.8.0.0 (Proteus) - Mainline/Release

Problem Description:

I performed a completely fresh installation of AMP after removing all previous AMP services, instances, datastore files, Docker containers, and Docker images.

Docker Desktop is installed and working correctly.

I verified my AMP installation by successfully creating and running a Valheim server inside a Docker container. SteamCMD downloaded the server correctly, the game started successfully, and the instance is fully functional.

The issue only occurs with Sons of the Forest.

When creating a Sons of the Forest instance:

  • The Docker container is created successfully.

  • The child AMP instance starts successfully.

  • The AMP webserver starts on port 8082.

  • SteamCMD launches.

  • No game files are downloaded.

  • The instance eventually fails because SonsOfTheForestDS.exe does not exist.

The deployment log shows:

Managed remote instance RedForrest01 at http://127.0.0.1:8082/
LIM - Failure to make API call to RedForrest01: An error occurred while sending the request.

The container itself is healthy:

docker ps -a

CONTAINER ID   IMAGE                            STATUS
faa79ab854e2   cubecoders/ampbase:wine-stable   Up

Container logs show:

Webserver started on http://127.0.0.1:8082

wine: failed to open "./SonsOfTheForestDS.exe"

The application stopped unexpectedly. Exit code 53

I manually entered the container and executed SteamCMD:

cd /AMP/sons-of-the-forest

./steamcmd.sh \
+force_install_dir /AMP/sons-of-the-forest/2465200 \
+login anonymous \
+app_update 2465200 validate \
+quit

SteamCMD returns:

ERROR! Failed to install app '2465200' (Missing configuration)

Afterward I inspected the install directory:

/AMP/sons-of-the-forest/2465200
└── saves/
    └── dedicatedserver.cfg

No game files or SonsOfTheForestDS.exe are ever downloaded.

This appears to indicate either:

  • the Steam AppID being used by the template is incorrect or no longer valid, or

  • the Sons of the Forest deployment template requires updating.

Since Valheim deploys and runs correctly on the same installation, I do not believe this is a Docker or AMP installation problem.

Steps to reproduce:

  1. Fresh install of AMP 2.8.0.0 on Windows 11 with Docker Desktop.

  2. Create a Sons of the Forest instance using the default deployment template.

  3. Start the instance.

  4. SteamCMD reports “Failed to install app ‘2465200’ (Missing configuration)” and no server files are downloaded.

  5. AMP attempts to launch SonsOfTheForestDS.exe, which does not exist, and the instance exits with code 53.

Actions taken to resolve so far:

  • Completely removed AMP and performed a fresh installation.

  • Deleted all AMP services and datastore.

  • Removed all Docker containers and images.

  • Reinstalled Docker Desktop.

  • Verified Docker is functioning correctly.

  • Disabled Host Networking for containers.

  • Corrected Default Auth Server to http://host.docker.internal:8080/.

  • Successfully deployed and started a Valheim server in Docker.

  • Verified Docker networking and AMP child instance communication.

  • Verified the Sons of the Forest container starts correctly.

  • Manually executed SteamCMD inside the container.

  • Confirmed SteamCMD returns ERROR! Failed to install app '2465200' (Missing configuration).

  • Verified the installation directory only contains the saves folder and no game executable.
