[Eli_H]

OS Name/Version:

Microsoft Windows 11 Pro
OS Version: 10.0.26100 N/A Build 26100

Product Name/Version: 2.6.5 - 20260114.3

Problem Description:

I am not able to run Docker based instances, I have tried creating Terraria (vanilla) and Tshock servers and I get the following error:

Unable to complete task

This task could not be completed: Starting Instance - Starting T Server Docker (TServerDocker01)... - State: 3.

Startup failure: Docker returned error code 125. Please check the AMP Logs for further info.

I went through this guide to setup Docker containers

Here is the related Deployment log

Run 'docker run --help' for more information

On Docker desktop, I can see that the container has been created:

So it appears that Docker containers and instances are created, but I am not able to start them on AMP.

Steps to reproduce:

• Followed these instructions to enable Docker container deployment.
• Navigate to AMP instance manager and create a new Terraria Server or Tshock Terraria server
• Instance is created, but fails to run it→ this is were I get the Unable to complete task error

Actions taken to resolve so far:

• Restarted PC
• Updated Docker & AMP
• Reviewed guide
• Deleted Docker container and recreated another instance.
