Description

During nemoclaw onboard on WSL2, after the sandbox container is created and the dashboard is confirmed live, the onboard output prints a warning: ! No active forward found for port 18789. Onboarding completes successfully despite the warning, but the port forward state is unclear and may affect external dashboard access.

Environment

Device:        Windows PC (x86_64) + WSL2 Ubuntu 24.04.4 LTS
OS:            Ubuntu 24.04.4 LTS (Noble Numbat), WSL2
Architecture:  x86_64
Node.js:       v22.22.2
npm:           10.9.7
Docker:        Docker version 29.4.3, build 055a478 (docker-ce)
OpenShell CLI: openshell 0.0.39
NemoClaw:      v0.0.47
OpenClaw:      2026.4.24

Steps to Reproduce

1. Install NemoClaw v0.0.47 on WSL2 Ubuntu 24.04:

   curl -fsSL https://www.nvidia.com/nemoclaw.sh | bash

2. Run onboard:

   nemoclaw onboard --no-gpu

3. Complete all 8 onboard steps (inference, messaging, sandbox build, policy).
4. Observe terminal output after sandbox creation in step [6/8].

Expected Result

No port forward warnings printed during onboard. Dashboard port 18789 is accessible after onboarding completes.

Actual Result

  ✓ Sandbox 'my-assistant' created
