summary: "Troubleshoot node pairing, foreground requirements, permissions, and tool failures"
read_when:
- Node is connected but camera/canvas/screen/exec tools fail
- You need the node pairing versus approvals mental model
title: "Node Troubleshooting"

# Node troubleshooting
Use this page when a node is visible in status but node tools fail.
## Command ladder
```bash
openclaw status
openclaw gateway status
openclaw logs --follow
openclaw doctor
openclaw channels status --probe
```
Then run node specific checks:
```bash
openclaw nodes status
openclaw nodes describe --node <idOrNameOrIp>
openclaw approvals get --node <idOrNameOrIp>
```
Healthy signals:
- Node is connected and paired for role `node`.
- `nodes describe` includes the capability you are calling.
- Exec approvals show expected mode/allowlist.
## Foreground requirements
`canvas.*`, `camera.*`, and `screen.*` are foreground only on iOS/Android nodes.
Quick check and fix:
```bash
openclaw nodes describe --node <idOrNameOrIp>
openclaw nodes canvas snapshot --node <idOrNameOrIp>
openclaw logs --follow
```
If you see `NODE_BACKGROUND_UNAVAILABLE`, bring the node app to the foreground and retry.
## Permissions matrix
| Capability | iOS | Android | macOS node app | Typical failure code |
| ---------------------------- | --------------------------------------- | -------------------------------------------- | ----------------------------- | ------------------------------ |
| `camera.snap`, `camera.clip` | Camera (+ mic for clip audio) | Camera (+ mic for clip audio) | Camera (+ mic for clip audio) | `*_PERMISSION_REQUIRED` |
| `screen.record` | Screen Recording (+ mic optional) | Screen capture prompt (+ mic optional) | Screen Recording | `*_PERMISSION_REQUIRED` |
| `location.get` | While Using or Always (depends on mode) | Foreground/Background location based on mode | Location permission | `LOCATION_PERMISSION_REQUIRED` |
| `system.run` | n/a (node host path) | n/a (node host path) | Exec approvals required | `SYSTEM_RUN_DENIED` |
## Pairing versus approvals
These are different gates:
1. **Device pairing**: can this node connect to the gateway?
2. **Exec approvals**: can this node run a specific shell command?
Quick checks:
```bash
openclaw devices list
openclaw nodes status
openclaw approvals get --node <idOrNameOrIp>
openclaw approvals allowlist add --node <idOrNameOrIp> "/usr/bin/uname"
```
If pairing is missing, approve the node device first.
If pairing is fine but `system.run` fails, fix exec approvals/allowlist.
## Common node error codes
- `NODE_BACKGROUND_UNAVAILABLE` → app is backgrounded; bring it foreground.
- `CAMERA_DISABLED` → camera toggle disabled in node settings.
- `*_PERMISSION_REQUIRED` → OS permission missing/denied.
- `LOCATION_DISABLED` → location mode is off.
- `LOCATION_PERMISSION_REQUIRED` → requested location mode not granted.
- `LOCATION_BACKGROUND_UNAVAILABLE` → app is backgrounded but only While Using permission exists.
- `SYSTEM_RUN_DENIED: approval required` → exec request needs explicit approval.
- `SYSTEM_RUN_DENIED: allowlist miss` → command blocked by allowlist mode.
## Fast recovery loop
```bash
openclaw nodes status
openclaw nodes describe --node <idOrNameOrIp>
openclaw approvals get --node <idOrNameOrIp>
openclaw logs --follow
```
If still stuck:
- Re-approve device pairing.
- Re-open node app (foreground).
- Re-grant OS permissions.
- Recreate/adjust exec approval policy.
