| OpenClaw dashboard URL not loading | Gateway not running or wrong host/port | Restart the OpenClaw gateway so it reloads ~/.openclaw/openclaw.json. Verify: Check that the gateway process is running with pgrep -f openclaw or ps aux | grep openclaw. Find URL/token: Check the original installer output (scroll up in your terminal) or look in gateway logs (typically ~/.openclaw/logs/) for the dashboard URL and access token |
| "Connection refused" to model (e.g. localhost:8000) | vLLM server not running, still loading, or wrong port | Confirm the vLLM container is up and finished loading (curl http://localhost:8000/v1/models lists the model) and that baseUrl in openclaw.json is http://localhost:8000/v1 |
| OpenClaw says no model available | Provider not configured or model handle mismatch | Add the vllm provider to ~/.openclaw/openclaw.json and ensure id/name exactly match the served handle (nvidia/Qwen3.6-35B-A3B-NVFP4) |
| Out-of-memory or very slow inference on DGX Spark | Model too large for available GPU memory or other GPU workloads | Lower --gpu-memory-utilization or --max-model-len when launching vLLM, free GPU memory (close other apps), or check usage with nvidia-smi |
| Install script fails or dependencies missing | Missing system packages on Linux | Install curl and any required build tools; see OpenClaw documentation for current requirements |
| Config changes not applied | Gateway not reloaded | Restart the OpenClaw gateway so it reloads ~/.openclaw/openclaw.json |
