OS Name/Version: Ubuntu 20.04.2 LTS

Product Name/Version: AMP (version 2.1.0.6 - originally upgraded from 2.1) - NOTE: I am using Docker for instances.

Problem Description: When attempting to create a new instance for Valheim, the configuration fails:

[08:49:36] [InstanceManager:[redacted] Warning] : Failed to configure new instance Valheim01 - Startup failure: Docker returned error code 1
[08:49:36] [InstanceManager:[redacted] Error] : Configuration Failed: Startup failure: Docker returned error code 1

Steps to reproduce:

• Install AMP (enable Docker for instances)
• Attempt to create Valheim instance

Actions taken to resolve so far:

• Updated all instances using nocache
• Attempted to try without Docker (appears to configure to launch fine outside a container)
